    Question.... Corbon 185 gr 45 acp...

    I was digging though some boxes and came across a full box of Corbon 185 gr JHP. I gave it to a friend and he gave it back saying it wouldn't chamber in his 1911 ( Scandium frame S&W E series ). I brought it home and tried it in my Springfield, and it seems to chamber fine. I looked at it and it seems to be belted in some fashion? Is this normal, and why would it feed in one gun and not the other?

    It looks like this...

    I've heard a lot of good things about that round. I was considering it, but I'm hesitant to get away from 230 grn.

    As have I but I prefer heavy for caliber bullets. I shoot 230 gr and I am not interested in shooting less.

    Had a Les Baer that did not like SWC's. The chamber may a tad tighter than your Springfield.

    I can't say anything about that ammunition chambering properly but it's plain to see that it's one potent horse of a .45 ACP load. While I too lean toward the heavy end of bullet weights available for any particular handgun cartridge, there's a lot of .45 ACP goodness in that screamer of a "light" bullet load.

    The issue with the Cor-Bon 185 Gr bullets is it cannot be bigger than 185 gr as it is all copper and really physically the same size as a 230GR bullet. Yes, some guns are picky and that is why for Social Ammo you need to run a couple hundred thru the gun to insure flawless function. They work well in my G-21 and 1911.

    If it's the round pictured in the OP, it's not the all copper DPX--it's a conventional JHP.

    However, I will say that the Barnes 185gr (aka DPX) is one of the most problematic loads I've ever run across, vis a vis feeding issues; I've had a couple of pistols that would feed pretty much everything choke on them.

    If the rounds actually are DPX, that would make a fair amount of sense...but it could be his buddy's pistol just doesn't like those rounds, even if they are conventional JHP's...it happens.

    It's not belted. The groove you see almost mid-way is a cannelure. It doesn't affect loading. Some 1911's are finicky on the types of bullets fed through them.

    They are indeed JHP and not the all copper bullets

    Per a previous discussion with a CB guy, these were developed for short barreled 45s, as the 230 grain does not develop the proper velocity with the shorties. Seems to be a sound idea, but it makes me wonder, if you tend to a short barreled 45 and thus require a lighter bullet, would you be better off switching to another caliber? Also what are the disadvantages, if any, of shooting these in a full size 45?

    Not if you're interested in entrance holes on the large size.

    I'm not a fan of of the Corbon 45 JHPs. Pocket Guns and Gear: Corbon 45 Auto +P 230 Grain JHP Denim and Clear Gel tests If a 230 grain JHP at +P doesn't expand from a 5" barrel, something is seriously wrong with the bullet design.

    Now the 9mm 125 +P was a much different story. It tested really well. Pocket Guns and Gear: CORBON 9mm +P 125 Grain Denim and Clear Gel Terminal test

    It will also depend on the chamber reamer used and whether the ammo was produced for min,med,or max SAMMI chambers.His Smith just doesn't like that ammo and if we knew exactly why we would be very rich by answering that question. They work in yours so blast them up.
