“Heavy” .25acp? Isn’t that a contradiction??

Last year Buffalo Bore came out with two loadings of what they called HEAVY 25 ACP Pistol and Handgun Ammo, saying that it was standard pressure but heavy-for-caliber and which met the FBI penetration criteria. We got some, and decided to do an informal test recently to see if it performed as promised.

First off, .25acp is not my preferred choice for a self-defense round out of any platform. When we tested the cartridge, the available SD ammo all came in at between 60 and 70 ft/lbs of muzzle energy (M.E.) That’s … not much. And penetration tests others had conducted were unimpressive. Sure, a .25 can kill, and Vasily Blokhin executed thousands of prisoners with one (well, several), but that hardly qualifies as self defense. Given the options, I’d almost always pick something better for protection.

But sometimes, you gotta go with what you got. And if all you have is a .25acp, at least you want the best ammo for it. That’s why BB came out with these two new loadings.

Since this was just an informal test, we only had a radar chronograph, and these two handguns to try:

That’s a Beretta 21A Bobcat on top, and a Bernadelli Baby .25 below it. The Beretta has a 2.4″ barrel, the Bernadelli a 2.0″ one. The Beretta is small, but the Bernadelli is tiny — I could only get my middle finger on the grip, holding the gun between that and my thumb with my index finger on the trigger.

Here’s the ammo:

That’s BB’s 60 gr. Hard Cast FN and the 50 gr. FMJ-RN loads, and you’ll find Buffalo Bore’s claims on those pages for how the loads performed out of four different handguns, including a Beretta Bobcat.

So, how did it go? Pretty well. Here are my data notes:

That’s an average of 841fps for the Hard Cast out of the Beretta, and 758fps out of the Bernadelli. The FMJ was 871fps out of the Beretta and 807fps from the Bernadelli. That’s right in the ballpark of what Buffalo Bore claims. Unsurprising, since Buffalo Bore has consistently performed as claimed, in my experience.

It’s also important to note that both loadings seem to meet the FBI’s penetration protocol. This indicates that it should be lethal if shot placement is good.

.25acp still wouldn’t be my choice for self defense. But particularly with the Buffalo Bore ammo, you could do worse.

Goodbye Tavor TS12, Hello KS7.

Two years ago, I closed a blog post with this:

Overall, I’m very happy with the Tavor TS12. Altogether I ran about 75 shells through it in an hour, half the light target loads, the other half full-power, high-brass slugs and 00Buck. It’s been decades since I shot a 12 gauge that much in that short a period of time, and my shoulder isn’t the slightest bit sore.

Yeah, the TS12 is a keeper.

Well, it was, up until this week.

Why? What happened?

This:

That’s a friend’s brand-new Kel Tec KS7.

Let me explain: one of the other BBTI guys got this, and brought it out to try … specifically, with 12ga minishells. Both Aguila slugs and Federal 4B defensive loads.

We ran a BUNCH of minishells through it. Not one single misfire, mis-feed, or problem. It just ate ’em all and asked for more. At 25 yards, we shot the sh!t out of targets for the better part of an hour.

And here’s the thing: with the minishells, the gun held 12+1 rounds (12 in the tube, one in the chamber). Recoil was modest, operation was simple and intuitive (as is the case with most pump shotguns), and the basic fiber-optic sight was more than adequate for the distances we were shooting (and for any expected use I would have).

By the time we were done, I knew I wanted one of these, if for no other reason than it would be much easier for my Good Lady Wife to handle if need arose. She had shot the Tavor, but never really took to it, and it was heavier and a little more for her to wrangle than she was really comfortable with.

Now, don’t get me wrong — I like the Tavor TS12. A lot. I still think that it is a hell of a gun, and it handles the full-power, full size 12ga rounds with aplomb. So I had zero qualms about offering it to an old friend, at a decent price, and then rolling that sale over into this:

I could have just kept the Tavor, of course, but I tend to have guns for specific uses, and the 12 shot KS7 filled the same niche as the 15 shot Tavor: home defense. I’ll probably put a light on it, but no optic — it’s just not needed with the standard fiber optic sight — though I may change my mind on that as time goes on. We’ll see.

In looking over reviews of the KS7 before I made the final purchase, one of the things that I read was that while using minishells was fine, loading minishells was a little more tricky than loading standard-sized shells, particularly under stress. And I think that’s a perfectly fair point; loading the slugs in particular was a little tricky.

So my solution will be to load the gun with minishells, but keep standard sized shells in a bandoleer for reloads (if they’re needed). It’s exactly what I planned for the Tavor if I ever needed it, so it’s no change at all for me.

One last thing: why not just get a KSG? That’s the double-tube 12ga predecessor from Kel Tec.

I’ve shot the KSG. Nice gun. But fully loaded, the KSG is closer to the Tavor in terms of weight and overall size. The real advantage of the KS7 is that it is thin, light, and basic. But I think it does come down to personal preference and intended use. YMMV.

ETA: got a request for pics of the sight on the KS7. Here ya go:

An informal .32 H&R Magnum test, and a lesson relearned.

I’m not a fan of the .32acp for self-defense. But the .32 H&R mag or the .327 Federal mag are both respectable options, even out of a short barrel revolver. Since the 100gr Buffalo Bore Heavy 32 H&R Magnum +P ammo load wasn’t available when we did the .32 H&R tests, we weren’t sure how it would perform. And we decided to do some informal testing to find out, learning another lesson in the process that I thought I’d share.

We had both 5 shot and 6 shot versions of the Charter Arms Undercoverette snub nose:

Charter Arms sometimes has “hit or miss” quality control, but generally they seem to work just fine.

Anyway, we did chrono ammo out of both guns, and it performed in accord with the Buffalo Bore claims on their website:

  • 1,054 fps – Taurus Ultra Light 2-inch barrel

That’s right at 250 ft/pounds of muzzle energy. Like I said, respectable. I sure as hell wouldn’t want to be shot by it.

However …

Take a close look at the primers.

Here’s another pic:

See how the primers stick up above the base of the case?

Yeah. Those are from the 5 shot version of the revolver. And each time, the primer protruded enough to lock up the cylinder, making the nice little revolver into a single-shot gun. And it happened every time.

It did not, however, happen with the 6 shot version. Same ammo. Same box. Completely different results. Oh, they chrono’d the same. But in one gun they rendered the firearm completely non-functional after the first shot.

So, the lesson: ALWAYS TEST YOUR CARRY AMMO IN YOUR CARRY GUN.

Yeah, I know you probably know this. I certainly know it, and always tell people to do it. But I’ve rarely seen such a clear object lesson showing it.

Why the difference? I don’t know. Could be that the recoil impulse in the 12oz version (the 5 shot) is just that much more powerful than in the 15oz version. That’s about the only thing I can think of.

Review: M&P FPC.

Sometimes, smaller *is* better:

Yup, that’s the new Smith & Wesson M&P FPC (Folding Pistol Carbine), which I got to shoot recently.

I’m a big fan of Pistol Caliber Carbines, and am on record loving my Kel Tec Sub2000 folding carbine in 9mm. That gun has served me well for the last 20 years or so, and I’m not ready to get rid of it.

But the new M&P FPC is tempting. And if I didn’t already have my Sub2k already tricked-out/upgraded to my personal preferences, I’d jump on getting one immediately.

OK, so there’s my bottom line. Now, let’s talk about what I like particularly about the M&P FPC, and how it compares to the Sub2k.

The M&P FPC is something of an extension of the M&P line of pistols. It can use the same magazines as both the original version and the 2.0 version. The fire controls are the same, as are the grip modules. Anyone familiar with the M&P pistols will find themselves at home with this new carbine.

As is typically the case with Smith & Wesson products, everything is well made, and fit & finish are fine. We had no problems with the gun right out of the box. The gun folds and unfolds quickly, and even a novice user gets the hang of that mechanism after one or two tries. Location of the charging handle and folding release are logical and easy to use.

We slapped a basic Sig Sauer Romeo red dot on it and sighted it in. After that, it was easy to shoot out the bullseye of a target at 25 yards (max distance on the range we used). Seriously, all three of us shooting it could basically make one ragged hole when shooting supported, and do almost as well shooting unsupported while standing. The ergonomics are great on this PCC.

Recoil was also better than I expected. Both guns use a direct-blowback action, but the FPC has a nice recoil buffer built in, making it a soft-shooting gun that will please even someone who is recoil shy. That’s one regard in which it is better than my Sub2000.

Also, since the gun folds horizontally (off to the left), rather than flipping up like the Sub2000, you can mount an optic on it and not worry about it getting in the way (or being knocked off zero). Another improvement over the Kel Tec.

The bolt holds open after the last round. My Sub2k doesn’t.

The charging handle on the FPC doesn’t reciprocate, so there’s less of a chance to snag clothing (or beards!). My Sub2000 charging handle rarely snags, but it can (and has) on occasion.

There’s a clever mag holder on the FPC that holds two additional mags in the buttstock, and it is easy to remove a new mag and load it into the gun. My Sub2k has no such holder.

The trigger is good on the M&P. I had to upgrade the trigger on my Sub2000 with an after-market product.

As I mentioned, it’s easy to shoot well, and the ergonomics are good. I had no problems getting a good sight picture while wearing earmuffs, while that is still a problem with my Kel Tec. And while the Sub2000 still feels short in my hands (after adding a stock extension), the M&P felt fine.

The M&P FPC is wider than the Kel Tec Sub2000, due to the folding mechanism. The difference is 2.5″ for the M&P, 1.75″ for the Sub2k, so it’s not insignificant. The M&P is also slightly heavier bare, and significantly so with two additional fully-loaded 23 round magazines. But the weight is well balanced.

And the M&P comes in a nice, nondescript padded carrying case.

It’s a great little carbine. If I didn’t already have my Sub2000 operating just as I like, I’d be tempted. And to be honest, I’m tempted nonetheless.
