More testing of more calibers coming.

Hey everyone,

Well, in less than two weeks we’ve seen over 200,000 hits to the site, and the news of our project propagate widely through the gun community and even beyond. There’s been a lot of discussion about our efforts, almost uniformly positive, and this is really good to see. Over 700 people have downloaded the data spreadsheets, and almost 100 have downloaded the emails documenting the project from start to finish.

This response, and the comments we have seen around the web, have prompted us to plan to do another round of testing this next spring. Sorry for the delay, but we need some lead time to have the custom barrels made and to plan our schedules.

After discussion, we’ve decided to test the following calibers:

.327 Federal Magnum
.41 Magnum
10mm

We feel that these help fill out the other calibers we’ve already tested, extending the coverage of the most common handgun calibers actually carried (with the exception of the .327 mag – we just want to see how that actually performs).

So, something to look forward to in the new year!

Cheers –

Jim D.

What about .22LR and .22 Mag? Both are commonly chambered in pistols.

Well, yes, they are. So are a number of centerfire rifle rounds. And we’ve kicked around doing all of these, perhaps somewhere down the line. But for now we’ve decided to concentrate on those calibers more commonly carried as self-defense weapons – an admittedly arbitrary decision on our part.

But *anyone else* is more than welcome to spend the time and money and conduct their own tests. Our deciding to do these, and only these (for now), in no way limits anyone else. They can do so, and put their data out there as we have – we’d even be willing to consider hosting it on our site with full credit to those who did the testing, if it seems to have been done in a rigorous way.

Cheers!

Just found the site, looking for ballistics for the .41 Mag. out of a carbine-length barrel.

Great site! Hope your “time off” helped–looking forward to the upcoming tests.

Thanks.

Thanks, Paul! Got word that the barrels are ready, and the ammo is starting to arrive. Probably sometime late next month we’ll see about scheduling the actual tests. Give us a couple of weeks to crunch the numbers after and get the info posted, and you’ll have whatever data we gather.

[…] sporadic (hmm – sounds like a weather forecast) this week. We’re going to be starting the next round of ballistics testing on Thursday, and I have a lot of work to get done before […]

Your site is amazing and the data priceless. I can’t believe that this hasent been done before. But as with most genious ideas no one thought of it but every one wishes they did. As a bit of an amature balistics number cruncher my self i have fallen in love with the 10mm and with the Glock 20 have finaly found an appropriate platform from which to launch it. since you guys are going to do further testing could i recommend the callibur (9×25 Dillon) and some ammo from (ww.doubletapammo.com)? I’m dieing to see how these things screem out of a long barrel. the (50-GI)would also be a verry interesting test to see if it reached usable velositys from a longer barrel. Both calliburs are conversions for my Glock 20 and both verry interesting as is the (Mech tech CCU)

Thanks for the feedback, and the comment! I can certainly understand why you like the 10mm – it’s quite the cartridge. I’m not sure there are enough people using the 9 x 25 or the .50 GI yet, but we do plan on revisiting all the handgun cartridges in a few years, after we have tested some other things, and maybe we’ll pick those up then.

Again, thanks – happy shooting!

thank you for the timely reply you guys rock. I figgured it was a long shot on 9X25 and 50-GI but you dont know how happy I am that 10mm is becomming main stream enough to make the cut.

Thanks again and keep up the awesome work,
Big Jon
