Consolidated List of Boberg Compatible .45 Ammunition

Consolidated List of Boberg Compatible .45 Ammunition  

Boberg's patented loading design is great and fits a longer barrel into a smaller package but some ammo that isn't manufactured up to specs may cause problems. This isn't a flaw of the gun but rather a flaw in the ammo - You can't expect to put cheap tires on a Ferrari and still expect it to go 0 to 60 in 3 seconds.

The problem has been separation of the bullet from the casing because of inadequate crimping by the bullet manufacturer (remember most guns PUSH the next round into the barrel and thus don't have problems with bad crimps. The Boberg PULLS then PUSHES the next round into place.) Plated ammunition is generally not able to be crimped very well. The lead is too soft for the case mouth to get any decent tension on the bullet. Full metal jacket or hollowpoint ammo, however, has a solid foundation for the case mouth to create tension during crimping.

The list will be updated as people post their experiences - please try to be as specific as possible regarding manufacturer, model, grain, FMJ/JHP, flat/round nose, etc. Manufacturers are constantly updating procedures when they identify deficiencies. For failed ammo, if you can identify roughly when ammo was purchased, the info will be posted for reference. 

Ammo with any reproducible issues is placed in the incompatible list but may still be usable for practice or by swapping the trigger spring for a heavier one. Most people will avoid regularly shooting ammo that separates because it is a pain to clean out, and the loose gunpowder flies right into your face. 

Disclaimer: Boberg Arms does not officially recommend any type of ammunition, nor does it guarantee the performance of any particular type of ammunition since we do not control the manufacturing of ammunition. We highly recommend that you test-fire ammunition at the range before carrying it for self-defense.

I got another chance to go to the range today and put another 100 rounds through my XR45-S.  Everything has worked well except for DoubleTap 160gr Barnes TAC-XP MANN (reduced load).  My first time at the range, I had two instances where a round got pulled partially out of the magazine and jammed just under the barrel, locking the slide open (IIRC, it was the 3d round in the magazine on both occasions).  In another instance, a round failed to feed from the magazine.  I did not have any jams today, but I di have another instance where the round did not load from the magazine.  

The results from everything else I have tried is reflected in the list above, in each case at least 20 rounds were fired. 

Here's a message by Luke Gardner copied from another thread with relevant information:

Shooting PMC Brass in my XR45-S, last Sunday I had very serious Feed/Eject issues. Pretty much every third round in most magazines I shot was getting kicked out live, most often down range. Picking up on Mark's thread almost immediately above where he discusses minute cartridge separations in the 147 Grain 9mm rounds triggering the same problem I was experiencing, I went back to the range today and shot the following ammo as a test to see if I could replicate the issue I was having with PMC Brass in 230 grain loads. 1) Sellier & Bellot 230 grain, 2) Winchester White Box, 230 grain, Remington UMC 230 grain.

First, a little background on this pistol:

It is a low serialed Onyx model XR45-S. The 4 magazines I have now contain the new shorter mag spring. Prior to shooting today I had about 200 - 225 rounds through the barrel. Accordingly, this pistol still has at the very least another 250 rounds to go before one can call it broken in.

Here are the results:

First Round

S&B 230 Grain. Due to very hard primers, S&B ammo is entirely incompatible with the XR45. I shot six rounds and gave up on the S&B. Out of the six rounds, 1 shot on the first strike, 4 shots on the second strike, and 1 shot on the 3rd strike. I also had three failures to feed and or go into full battery. My strong suggestion is DO NOT USE this ammo in an XR45.

Winchester White Box 230 Grain: Three Magazines, 6 rounds each. Zero failures in all 18 rounds.

Remington UMC 230 Grain: Three Magazines, 6 rounds each. Light strike on the first round only, thereafter no failure incidents.

Second Round

Winchester White Box 230 Grain, 28 Rounds, continuous shooting, re load and shoot again. 3 Failures to Feed, 1 Live round eject. The failures happened toward the end of the round in a very hot gun. I attribute the failures primarily to metal expansion due to hot internal mechanisms and an increasingly fouled gun.

Following the series, I removed the slide and allowed the internals to cool for about 5 minutes before re-assembling and shooting again.

Remington UMC 230 Grain: 29 Rounds, continuous shooting, re load and shoot again. Again, 3 Failures to Feed, 1 live round ejection. Again, the failures happened toward the end of the round in a very hot gun. Once again I attribute the failures primarily to metal expansion due to hot internal mechanisms and an increasingly fouled gun.

To sum up: My XR45 has between 250 rounds and 750 rounds to go before she is broken in. Based on my experience with both the XR9-S and the XR9-L, I am inclined to call it a 1000 round break-in period.

Incompatible:

PMC BRASS: FTFs FTEs and Live round ejections, likely caused by minor bullet pullout due to lightly crimped cartridges.

SELLIER & BELLOT: Multi-hammer strikes due to very hard primers, failures to go into full battery.

Compatible

Remington UMC 230 Grain

Winchester White Box 230 Grain

Hornaday Critical Duty 220 Grain FlexLock (On a previous range trip, I had shot 20 rounds of this entirely without incident)

Posted by "Jim" on December 3 @ +/- 3:00 PM E.T. in "Who Recv'd their XR45 and what #?"

I just got back from the first trip to the range with my XR45-S Onyx.  Remington 230 grain JHP will NOT load & will NOT cycle.  Changed to Federal 230 grain FMJ RN & had one fail to feed & then all the rest (30 rounds) of the Federal FMJ were ok. I now see that the XR45-S does not stay open after last round.  I am happy with the light(er) recoil due to the design. My groups were very good for 30 feet, but were low due to my own problem of dropping point of aim before trigger released.

Hey Jim:

Thanks for posting your results.  I am not familiar with the Remington 230 JHP. Is it a wide throat JHP bullet?

The reason I ask is that my and many other's experience with the XR45-S' 9mm siblings has been that they do not digest wide throat JHPs very well, although some owners have had no issues with them. I also remember reading somewhere (probably in the 9mm compatible ammo forum) that wide-throat JHPs become well tolerated once the gun is fully broken in. That is all to say that your mileage with them may vary.

Here is a list of ammunition that has worked in my XR45's

   -Federal HST 230 gr HST

   -Speer Lawman 185 gr TMJ

   -Speer Gold Dot 200 gr +P GDHP

   -Liberty Civil Defense 78gr 

   -Winchester White Box 230 gr FMJ 

I have had no separations and no problems with these once I got my magazine problems solved.

Luke,

I am not familiar with the term "wide throat JHP". I'll have to read up on that. These are the white & green Remington boxes. Mine were the Walmart value pack of 100 rounds, marked 45 AUTOMATIC 230 GR. JHP. It was such a deal I got 3 boxes ($57.77 each + tax).

I went through my ammo box and I see I left off this in my last post.

   -Federal 230 gr HST +P

Great Deal @ 57.77/Each??? Geee, I think I could do better here in CT.

My groups were very good for 30 feet, but were low due to my own problem of dropping point of aim before trigger released.

I was able to get to the range again last week, and did some measurements to see what kind of bullet movement was happening.  My process for this was to measure the OAL and find a group of representative rounds that had the same OAL.  I would then (1) fire 1, eject one, fire one, eject one, (2) re-measure the OAL, then (3) fire the previously loaded rounds.  I started with a gun that already had ~100 rounds through it, and fired a couple of magazines for warm-up.  After that, I alternated firing the XR45-S and a 1911, so the XR45-S never got super hot, but it was very dirty by the end, having close to 200 rounds through it without cleaning.  The numbers below show the average measurement of the pullout for  3 rounds:

American Eagle 230g RN - .012

DoubleTap 160g +P - .011

Liberty Civil Defense 78g +P - .001

DoubleTap 160g MANN (reduced) load - .015

  * one of the rounds had .040 pullout, the others were less than .010

Magtech 165g +P - .010

Hornday Critical Defense 185g FTX - .014

Winchester 230g PDX-1 JHP - .0233

  *although I had previously run several magazines of this ammunition through without any problems, I had 2 live rounds ejected; at this point, the gun was very dirty and fairly warm.  

Corbon  185gr DPX +P - .031

  * one of the rounds separated to 1.286 OAL (.050 longer than it started).  When I attempted to run that round through a second time, it separated.  Not surpsing, since it was pulled out quite a lot initially and was over spec for any .45 ACP

I've listed these in the order that they were done.  Since the 2 negative results I got were the last tests, it's possible the state of the gun (warm and very dirty) had a negative effect.  However, I did fire a few more rounds of other ammunition through the XR45-S after the last tests without any issues.  

Based on the higher pullout measurement and the ejections of the Corbon 185g DPX +P and the Winchester 230g PDX1 JHP, I'm inclined to move them to the incompatible list, although I also think there is a good chance they would work fine  90% of the time.

Thanks Art, good to know.

I have tested Federal 230 HST and had from .008" to .015" pull on 5 rounds.  

Speer Lawman 185 gr TMJ - .001" on 5 rounds tested.

My question is what is acceptable and what is not?

Today I was finally able to get back out to the range with my XR45. A mixed bag of results.

On today's ammo menu are two relatively new offerings from SIG Sauer and DoubleTap

First up was Sig Sauer's new Elite Performance Ammunition in .45 JHP - 200 Grain

Course of Fire - 3 Magazines - 6 Rounds Each @ 25 Feet

Mag 1 - No Mishaps in 6 Rounds

Mag 2 - 1 Failure to Load on the 3rd bullet in the magazine, 1 light strike on the last round.

Mag 3 - 1 Live round ejection on the 4th round in the Magazine, 2 light strikes: One on the 2nd round in the magazine, one on the last round in the magazine

Next up was McNett's DoubleTap 450 SMC in 185 Grain Bonded Defense JHP.

Course of Fire - 3 Magazines - 6 Rounds Each @ 25 Feet

Mag 1 - No incidents in six rounds, flawless fire

Mag 2 - No incidents in six rounds, flawless fire

Mag 3 - One incident: 1 light strike on the 5th round

Mag 4 (2 Rounds) No incidents.

SUMMARY

Sig Ammo: I can't presently recommend the Sig Elite Performance ammo given the results above. I may try to shoot it again once I have a good 1000+ rounds through the barrel.

DT's 450 SMC: I think the results above pretty much speak for themselves. Caveat: the 450 SMC is a short magnum cartridge. Accordingly it is a very feisty round but not at all unmanageable using a good firm grip. In fact - as the target immediately above confirms - I shot it far more accurately than I did the much lower powered Sig Elite ammo. All in all, I do recommend it, but it is a very fast round and some ranges backstop materials may not be able to handle it.

I finally made it to the range the other day for a short session with my XR45-S.

I went through a 50 round box of Federal 230gr FMJ RN, but had one FTF on the second magazine mid-magazine. I dropped the magazine, could not rack the slide to clear the round, so a palm strike to the rear of the slide drove the round into the chamber and I then fired it. I reinserted the magazine and resumed firing for the rest of the box of ammunition.

I also went through 16 rounds of GECO 230gr FMJ RN without incident before moving on to shooting Federal 124gr HSTs in my XR9-S.

I fired more accurately with the XR45-S than with my XR9-S, which may be a function of the overall longer length, longer sight radius and more pistol mass. I was not expecting that. The recoil of the XR45-S is much less than what I was expecting and very manageable. I noticed that adding the sixth round into the XR45-S magazine is easier than adding the seventh round into the XR9-S magazine
