With a little luck in about two months we’ll be doing the formal chop tests of .45 Super, .450 SMC, and some additional .45 ACP loads. We’ve now got all the ammo on hand, and it’ll be a fun (but tiring) weekend. I thought I would share what actual ammo we will be testing, with the manufacturer’s velocity data:
45acp Low Recoil Std P 185gr FMJ-FN 850fps
45acp Std P 230gr FMJ-RN 850fps
45acp +P 185gr JHP 1150fps
45acp +P 230gr JHP 950fps
45 Super 185gr JHP 1300fps
45 Super 200gr JHP 1200fps
45 Super 230gr FMJ 1100fps
45 Super 230gr JHP 1100fps
45 Super 255gr Hard Cast 1075fps
45acp +P 160gr Barnes TAC-XP 1200fps from 5” 1075fps from 3.5”
450 SMC 185gr JHP 1310fps from 5” 1911
450 SMC 185gr Bonded Defense JHP 1310fps from 5” 1911
450 SMC 230gr Bonded Defense JHP 1135fps from 5” 1911
Critical Defense 45acp Std P 185gr FTX Muzzle 1000fps
Critical Duty 45acp +P 220gr Flexlock Muzzle 941fps
45 Super 170gr CF 1250fps
45 Super 185gr XTP JHP 1300fps
45 Super 230gr GD JHP 1100fps
In addition to the first data for both the .45 Super and .450 SMC cartridges, this will also almost double the number of .45 ACP loads we’ve tested. We’re looking forward to it!
Well, we’re having another delightful warm spell here in mid-Missouri, so yesterday afternoon I took advantage of it and went out to the range to give the little guy a try.
As I noted before, I have actually shot this particular gun a couple of times previously, and just loved it. But it had been a while, and I couldn’t remember specifically what ammo types we had used. So I packed up what variety of 9mm loads I had on hand, along with my chrono, and went to see whether anything had changed.
Because of the way they operate, the Boberg pistols have a tendency to be very particular about what ammo they like. Ammo which doesn’t have a sufficient crimp is prone to separate (the case being jerked away from the bullet). It’s an issue which is well known, and there’s a list of compatible ammo for both the XR9 and the XR45. But while those crowd-sourced lists are useful, the final word is always what specific ammo your particular gun will handle. For me, that’s particularly something I want to determine for any self-defense pistol before I will carry it.
Full details to follow, but for those who just want the short version: oh baby! The XR9 ate everything I fed it without a problem. Including my standard 9mm reloads. No mis-feeds. No bullet separation. No problems. And it was a real joy to shoot, which isn’t something I normally say about a pocket pistol handling full-power SD loads.
OK, for those want the details …
Below are informal* chrono numbers for seven different ammo types I had. These are all for the Boberg. But I also ran a few through my Steyr S9 for comparison, which usually just had an advantage of about 10 fps over the Boberg (the barrel on the Steyr is about a quarter of an inch longer). If that much.
- Buffalo Bore 124gr JHP +P+ 1,230 fps
- Federal 124gr Hydra Shok JHP 1,025 fps
- Reloads. (4.4gr HP-38, 124gr Rainier FMJ bullet) 1,020 fps
- Remington 124gr FMJ 1,040 fps
- Speer GDHP 115gr JHP 1,210 fps
- Speer GDHP 124gr JHP 1,100 fps
- Speer GDHP 124gr JHP +P ‘Short barrel’ 1,150 fps
As you can see, all pretty respectable numbers. And in keeping with both the claims of the manufacturer as well as what we had tested previously (where there’s overlap). I wouldn’t have any qualms carrying any of the Speer ammo, but my preferred SD ammo is currently the Buffalo Bore. Happily, the Boberg shot all of them without a glitch. And after getting my chrono numbers, I ran several magazines worth through the gun doing some quick shooting at cans, was getting excellent accuracy from it at about 15 yards.
I brought it home, stripped and cleaned it, and now consider it reliable enough to carry. Of course, I will continue to practice with it regularly, and keep a close on on how it performs with my reloads, and occasionally run a mag of carry ammo through it, but I don’t expect any problems. It’s a nice little gun.
*By ‘informal’, I mean just using one chrono and without the lighting rig we now use for formal testing. And I would just run a magazine of ammo through, mentally noting the numbers in a running tally, then writing them down for that particular ammo, so they are necessarily just ‘ballpark’ figures. But since they jibe well with our previous numbers and what the mfg claims (which I only discovered when I sat down to write this), I think they’re pretty good.
As Frank said on Facebook this afternoon:
I knew when you got the 45 you wanted the 9mm too. It was only a matter of time.
Guilty as charged. Look what followed me home today:
Yup, a Boberg XR9-S: a new little brother for my XR45-S. As I did in that post, I thought I’d put up some comparison pix to give a sense of just how small this gun is, even though it really doesn’t feel like it when you hold it or shoot it.
Here it is again with the XR45:
And here’s the view that shows the thickness of both:
Yeah, there’s a difference. Here’s the XR9 with a Springfield EMP (also 9mm, 3″ barrel – the XR9 has a 3.35″ barrel):
And with my J-frame in .38 Special:
For grins, here it is on top of the J-frame:
OK, but how about in comparison to the classic premium pocket 9mm, the Rohrbaugh R9? Here ya go:
The R9 *is* a fantastic little gun, and I love it. I don’t love shooting it, though. The XR9 wins in that category. It will also handle +P ammo and holds one more round (7+1) than the Rohrbaugh. But it is a bit bigger:
Lastly, here it is with a Bond Arms derringer — a great little gun, with a variety of different barrels available. But there’s still just two shots in the derringer, and it actually weighs about 3 ounces more.
While I have shot this gun (it belonged to a good friend), and know it to be dependable, I do still want to make sure that it will be able to reliably digest my preferred SD loads. So more on that to come!
First, I want to share a couple of things I discovered in getting the Boberg out of the box, taken apart, and cleaned. This wasn’t strictly necessary, of course, because it came from the factory properly cleaned and lubed. But I’m very much a hands-on learner, and wanted to see what I was dealing with.
The gun is very user-friendly. To take it down for field stripping, you just rack the slide back, turn a lever, then move the slide forward. You don’t need any special tools, or an extra hand, or the strength of the pure. In that sense, it is very much in the modern design, as easy as a Glock. BUT without the need to dry-fire the gun first (which always makes me twitch, and may be the only thing I really dislike about the Glock design.)
Once the slide comes away from the frame, there are only 4 parts which come apart (other than the slide itself). There are no little fiddly bits to get lost or to spring out of sight when you’re not looking. You don’t have to disassemble the gun in a paper bag so that you don’t lose anything. It’s easy, obvious, and once you’ve done it following the owner’s manual, I doubt you’ll ever need to refer to the manual again. You can’t ask for more than that.
So, dis-assembly, cleaning, and re-assembly is all a breeze. Nice!
Having done so, I went through my box of misc. holsters to see what the Boberg might fit into. Because the XR45 is so new there are damned few holster-makers out there who have a holster listed to fit it. And I discovered something VERY interesting: the slide has almost the exact same dimensions as the Glock 21 (and similar Glock models). I first found this out in trying it in this little plastic holster: Glock Sport Combat Holster. I got out my calipers and did some measuring, and found that there was less than a millimeter difference in the width of the slide on the Glock 21 and the Boberg. They also have very similar profiles. And if you measure from the deepest pocket on the backstrap of either gun (where the web of your hand settles in) to the front of the trigger guard, there is less than 2 millimeters difference. Meaning that the Boberg fits almost perfectly into an open-muzzle holster for a Glock 21. Good to know!
OK, so what about going out shooting with the Boberg today?
Overall, I was very happy with how it performed on a first outing. I had a couple of minor glitches with improper feeding and ejection, but I am going to hold off on making any decisions about that until I give it at least another range session to break in. It does seem to fling spent cases somewhere into the next county, and I’m going to have to get used to that since I like to recover those cases and reload them. My very mild reloads wouldn’t cycle properly (the ones I took out are *really* mild), so I learned to take somewhat hotter loads. And the trigger is really l o n g … longer than either J-frame I own, and about like the little DAO Rohrbaugh I have. The gun seems to shoot a little to the left for me, but I won’t adjust the sights until I’m more familiar with it. Even so, I was able to consistently ding a 6″ spinner at 10 yards, which is all I expect from a pocket pistol.
How did it handle the different ammos I tried? Quite well, all in all.
I took my Glock 21 (5″ barrel) along for comparison, and shot over a single chronograph. Here are the average numbers:
Glock 21 Boberg
CorBon DPX 185gr +P 1060FPS 1030FPS
Winchester SXZ Training 230gr 850FPS 795FPS
Speer GDHP 230gr 840FPS 760FPS
CorBon JHP 230gr +P 980FPS 900FPS
The CorBon ammo is in line with what we tested formally. So that was good to see.
All together, I put about 100 rounds through the Boberg this afternoon, and wasn’t experiencing any real soreness or tiredness from all that shooting, which is unusual for such a small gun and full power loads. And just for comparison, I shot my .38Sp J-frame with 158gr LSWCHP +P from Buffalo Bore, which is my preferred SD loading for that gun, and the recoil was worse than with the Boberg. That’s for a ME comparison of 386 ft/lbs for the J-frame to 436 ft/labs for the Boberg with the 185gr CorBon loading.
So, that’s that. Already, the Boberg is equal to the J-frame, in my eyes. I shoot it as well. It has the same, or greater, amount of power. Reloading is faster. And it holds 6+1 to start. I still want to put it through its paces before I trust it as a carry gun, and there will be times when I still prefer to have the revolver, but already I can see that the Boberg is going to be a very nice addition to my collection.
