Ammo shortage? What ammo shortage??

Oh — THAT — ammo shortage.

Yeah, the beginning of January I wrote that we were finally moving forward with the testing of polygonal vs. traditional rifling; the so-called “Glock Tests“, and outlined how we were planning on conducting a bit of an experiment in asking for suggested ammo loads to include in the tests, and then seeing what kind of support there was for a slate of different choices by allowing pledges to help purchase ammo.

But, as someone who wrote me put it: where did we think we were going to *find* any such ammo?

Initially, I thought that the shortage we were seeing would be a fairly temporary problem, and that by the time spring rolled around we’d be able to locate sufficient quantities for our testing (we need about 350 rounds of each type).

Yeah, so much for that idea. Now you know why I don’t play the stock market or bet on races.

The ammo shortage has just continued to deepen. It’s to the point where people are having a hard time finding enough of any kind of ammo just to keep in practice with a trip to the range once or twice a month.  I’m damned glad I reload my practice ammo, and have a decent store of most components.

But that doesn’t do a damned thing for our testing. The whole idea is to test factory ammo, not some cobbled-together handload version of factory ammo.

So we’re putting off the “Glock Tests” again, until the situation gets better. Keep an eye here and elsewhere for news about when this will change.

One good bit of news, however: we already had a decent selection and sufficient quantity of each ammo type to do the .22WMR (.22Magnum) tests.  So we’re going to go ahead and do that sequence of tests here this spring — sometime soon!

Sorry for the bad news, everyone — really. These tests have been delayed several times for one (good) reason or another, and we’re just as frustrated by that as everyone else.  But when ammo supplies start to become more available, we’ll be sure to try and get them done as soon as we can.

Cheers!

Now, about those “Glock” tests…

As mentioned previously, for some time we’ve been planning on doing a series of inch-by-inch chop tests on the Glock-style polygonal barrels  (Glock was unable to supply 18″ barrels, so we’ll be using 6 grove poly and 6 land traditional barrels from Lothar Walther).  We’ve run into a number of unexpected delays, but now have the barrels we need, and are planning on doing the series of tests sometime later this year, hopefully in spring/early summer. For testing purposes, we’ll be conducting traditional ‘land & groove’ barrels in the same calibers at the same time, so that we have direct head-to-head comparisons. Because we’re expecting a fairly subtle difference in performance, we’re going to do 10 (ten) shots for each inch of barrel for both style barrels. And to keep the scope of the project manageable, we’re only going to test two cartridges/calibers: 9mm (9×19) and .45 ACP.

In order to do the tests this way, we’ll need a minimum of 340 rounds of each ammo to test. Add in “real world guns” and allowing for errors/glitches which mean extra shots, we’re planning on getting 400 rounds of each ammo to be tested. Figure an average of about $1 per round for premium self-defense ammunition, and we’re looking at about $400 for each ammo selected for testing. There are some specific ammunition types/loads we’ve tested previously that we want to revisit for comparison purposes, but our selection is hardly comprehensive — time and money are limited.

So we’d like to try an experiment: do Kickstarter-style crowdfunding to see what ammunition types/loads people want to have us test. This will allow two things:

  1. To let people help support the project by offsetting our costs.
  2. To help us find new ammunition types/loads.

Now, Kickstarter itself isn’t firearm-friendly. And that’s OK — we can do this on our own, just using our own site. What we’ll do is put up a list of different ammo types/loads, and solicit donations targeted for each during a specific time frame. When pledges are made, we’ll keep a running tally total for each ammo, and once it crosses a certain threshold, then that specific type/load will be added to our testing list.

But first we need to create our list of ammo. So, for the next two weeks, either add a comment to this blog post or send an email to info@ballisticsbytheinch.com with one specific 9mm ammunition type/load you would like to see us test. Please, just one type/load per comment or email, and just five or six such entries per person. I’m going to have to collate these myself, so help make it a little easier on me. Just sending in a selected ammo doesn’t obligate you to support that ammo with $ in the second phase of this test, but it’s probably a good idea to only recommend ammo you would be willing to actually support, and ones you think you can get others to support. And remember, keep your recommendations limited to factory mass-produced ammo; handloads or artisanal ammo which the average person doesn’t have access to will not be selected for inclusion in the tests. Also: we’re only accepting recommendations and donations from individuals, not ammo manufacturers.

You can see all the 9mm ammo we’ve tested previously here: 9mm Luger Results.

As I said, this is an experiment. If it works for selecting 9mm ammo to test, we may extend it to the .45 ACP tests, and then see about using a similar approach for other testing. We hope that this will be a way we can expand our research and make it more responsive to what data the firearms-enthusiast community wants to see. You can help by sending in your suggestions, but in also spreading the word on the different forums/blogs where our data may be used.

Thanks, everyone, for your ongoing interest and support!

And once again…

…I am reminded of how happy I am to not have to deal with the public day in and day out.

As I said two months ago:

People really will always find something to bitch about, won’t they? Even if it is free & unencumbered research data that they can’t get elsewhere.

This time I got a complaint from someone about our having excluded a particular make of handgun. No “Hey, thanks for the data, I wonder why you haven’t tested This Brand?” Or “I love the site, but is there a reason why you’ve not included This Brand?” Just an email with the header “WHY NO GLOCKS TESTED?” Yeah, all caps. Nothing else other than the question repeated in the body.

I actually get some variation of this  question just about every week. Let me rephrase that: at least every week. Which is why that question is at the top of the FAQ on the BBTI site.

I responded, as I usually do, with that link and some variation of: “we didn’t include them because we hate them” (which is joking off of what the FAQ says). Usually this takes care of the issue.

But sometimes people either don’t go look at the FAQ, or are too dense/sarcasm-impaired to “get” my response. That was the case with the current querent. After a couple more exchanged emails I finally convinced him that we don’t actually hate Glocks.

But the truth is, we *have* intentionally excluded Glocks so far. As I told my querent in my final email:

There are a lot of different factors which go into the selection of the guns we include in our tests. Glocks have a different barrel structure, so comparing them with the ‘standard’ rifling tends to skew results. For this reason we’ve so far avoided including them.

I say “so far” because we’re presently in the process of finalizing a test sequence where we do the formal inch-by-inch chop tests on Glock polygonal barrels. It’s taken us two years to be able to get the necessary 18″ blanks to do this properly. Having that data will allow us to do head-to-head comparisons with the ‘standard’ rifling results, and so give everyone data which actually is useful rather than just anecdotal. And yes, as part of that sequence we will be testing actual Glocks in different calibers and with different barrel lengths. We hope to be able to conduct these tests yet this fall, but are waiting on the gunsmithing work to be done.

This isn’t actually “news” – I hinted at it in June on the BBTI Facebook page (which you should “Like” if you’re on FB, so you see these things sooner), but it is the first I’ve mentioned it here or on any forums.

Anyway, yeah, I’m glad I don’t have to deal with the public on a daily basis any longer. My blood pressure problems would be a lot worse than they actually are.

Great new resource.

The folks over at LuckyGunner.com have started a blog, and the first post up is some really solid data from their testing of the differences between 5.56 NATO and .223 Remmington. From the post:

The differences between .223 Remington and 5.56mm NATO have been hashed out many times on the internet. Unfortunately, many of the “facts” that are often thrown around are simply what someone has heard from someone else, leading to a lot of misinformation being accepted as gospel.

In order to create this article, I temporarily set aside all of my previous knowledge and opinions while several months’ worth of new research and experimentation on the topic was undertaken. In addition, extensive discussions with gunsmiths, ballisticians, and laboratory technicians were conducted.

My findings, and the opinions of many experts in the industry who deal with the topic every day, were not exactly what some might expect. In fact, many of them had already discovered what I am reporting, although my research was conducted independently.

It’s a long, and really solid piece of research. If this is going to be typical of their stuff (and I think it will be — I know one of the guys involved with this, and respect his intelligence & commitment a lot), then this will be one hell of a great resource for those of us who are looking for good information that we can trust.

Check it out!

June? Already?

Yeah, seems to be. So here’s the numbers & info for the last month, plus a little look ahead:

We had 19,937 visitors to the BBTI homepage in May. We’ve added a number of additional review links to the list of Real World Guns. Followers for both Twitter and Facebook have also seen a nice uptick this last month.

Back in March I reported on how Google Adsense had screwed us over. Well, after looking at a number of options and being realistic about what kind of revenue advertising could generate, we’ve pretty much decided to just give up on advertising — with one small exception for now: you’ll note that some of the BBTI pages have a small ad promotion my novel. It is proving to be very popular, and the reviews for it have been quite positive — check it out. Of course, we’re still happy to accept donations to help offset expenses associated with BBTI — and thanks to those who have donated!

Happy & safe shooting, everyone!

…bring May flowers.

Well – I see that I didn’t post stats last month for March. Sorry about that – a combination of being busy promoting my novel as well as getting together with some of the other BBTI guys to do some fun shooting (and to try out a .460 Rowland conversion kit for a Glock 21!).

So, first things first: March had a total of 21,499 visitors, and April had 19,918 visitors. Just a bit of a slow period there.

Next, remember that we’re now linking from the BBTI page on Real World Guns to reviews of said guns I’ve written for Guns.com. There are usually a couple new each week, so check back often!

And here is the first of some additional reviews from my shooting expedition the beginning of April: Wise Lite Arms Sterling 9mm. Coming weeks should see more than a dozen other reviews of handguns and PCCs (pistol caliber carbines).

A quick note that things with my novel have been going great, and so far some 14,000 people have downloaded the Kindle edition. If you enjoy my reviews and articles, then you may want to check out the book – it’s been getting a lot of really good discussion and reviews.

Now linked to reviews.

Good afternoon!

Just wanted to let folks know that we’ve updated the BBTI “Real World Guns” page to include links to all the reviews I’ve done of those guns for Guns.com (where I am a writer). Currently that includes over 40 different reviews, and we’ll be adding more periodically as they run at Guns.com.

This is convenient for two reasons: it gives everyone a chance to see and learn about the guns we’ve used, and it gathers together in one place a lot of my reviews for reference. Of course, you can also just check my profile on Guns.com if you want to see *all* of my reviews and articles.

Cheers!

.22 article is now up.

As most know, one of my sidelines is as a feature writer and reviewer over at Guns.com. I don’t cross-promote all my articles or reviews here, but if you’re interested you can find them under my profile there.

Anyway, there’s a new article up there about our .22 tests and the resultant data. Check it out:

A little chat.

Here’s something for the .460 Rowland fans and those curious: Dear Santa: I want a .460 Rowland AR Upper

Had a bit of fun with that. Though admittedly, I have an offbeat sense of humor…

Naming names.

I mentioned the other day that we are offering brass from the recent Cylinder Gap tests as a ‘premium’ thank-you for donations received.

Well, that info, as well as recognizing those who have made a donation to BBTI, are now listed on a new page for donations on the site. Of course, only those who wish to have their name listed do – others who prefer to remain anonymous can (and have) done so.

So far I’ve sent out 1,000 cases of .357 brass. I still have something like 1,100 of that cartridge remaining. And about 500 cases each of .38 Short, .38 Long Colt, and over 2,000 cases of .38 Special. I’d love to find homes for all of it.

Bullets of light. And the other sort.

Wow: a milimeter-long pulse of laser light caught with a camera taking images at a trillion frames per second.

Description from the site:

Volumetric Propagation: The pulse of light is less than a milimeter long. Between each frame, the pulse travels less than half a milimeter. Light travels a foot in a nanosecond and the duration of travel through a one foot long bottle is barely one nanosecond (one billiongth of a second).

There’s complete description of how they do this, along with other videos and images of this effect, there at the MIT site. To see a bunch of great high speed video of actual bullets, check out the work done by Brass Fetcher.

Got brass in pocket?*

Edited 2/3/2012 to add: Thanks for the response! All the once-shot brass has now been spoken for.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

OK, as everyone knows, we’ve just put up a whole bunch of new data, most of which was generated during the early part of this past summer.

The bulk of that was generated during the Cylinder Gap tests, shooting .38 Shorts, .38 Longs, .38 Specials, and .357 Magnum rounds. And as a result we had two five-gallon buckets filled with spent brass.

Over the weekend I started doing some re-arranging of my reloading stuff, and it was time to tackle all that brass. I sorted it all. Then started cleaning it. So far I’ve run about 3000 .38 Special cases through the tumbler. And there’s a whole bunch (like 1600) .357 Magnum cases up next. Then the .38 Shorts and the Long Colt cases. This is more brass than I’d use in a couple of lifetimes (and I already have a couple thousand cases from previous tests and my general shooting).

So, here’s the deal: make a donation to BBTI, get some cleaned brass. Yup. For each $10.00, you get 100 cases of your choice (so long as supplies last, postage-paid in the US). This is all premium, brand-name brass, fired once. You can reload it. Or trade it. Or just keep it as proof of your support of our project. Frame it, for all I care.

So, help me out – take some of this brass off my hands.

8 million hits in the naked city.

Hey everyone -

Long time, no posts. Sorry about that. The summer and fall were filled with a lot of different high-intensity projects. But I have several things to share this morning…

One, we broke 8 million hits to the BBTI website about a week ago. That’s in just under 3 years time. Congrats to one an all, and thanks.

Two, barring unforeseen complications and general catastrophe, *tomorrow* we’ll launch the completely revamped BBTI. It will contain all the data that you know and love, but there will be a lot more. Like:

  • Data on our .22 chop tests this summer – 10 different ammos, and also 20 ‘real world’ .22 guns.
  • Data on our .460 Rowland chop tests last spring – an impressive cartridge!
  • Data on our .223 chop tests this last spring – Yup, it is definitely a rifle cartridge.
  • Data on our HUGE ‘Cylinder Gap’ tests this last spring, involving over 6,000 rounds fired. Some very interesting results.
  • Revised means of navigating the site, to reflect the way people have been using it, in order to make it faster and easier.
  • A comprehensive list of the 99 different ‘real world’ guns we’ve tested so far.
  • A bunch of new graphs and charts and data sets for your inner ballistic geek.
  • Some new links and other goodies.

So, get the champagne on ice, find your party hats – there’s gonna be a celebration tomorrow as we launch this new ship!
