45 ACP SWC

[ArchAngelCD]

I agree, the rounds look a bit short. Some ramps need the bullet tonight hit before the brass case. it sorta guides the rest of the round into the barrel. I'm not sure if you said, what is the OAL of those rounds?

Good luck. I tried loading 200-grain SWCs in my Glock 30 and never could get them to function regardless of COL or amount of crimp. Switched to 230-grain LRNs and it runs 100%.

Post #5! Krogen is spot on.
I shoot a ton of 200g SWC 45 in USPSA. I too had issues on occasion and the culprit was the edge of the brass catching as it entered the chamber due to the bullet shoulder not being exposed enough. Yours looks way to under exposed, like mine were. After I set it up a bit higher (.040") never had another issue. And its mainly shot in a SA Range officer as well as others too. It most likely is not the crimp! 1.250" OAL
You can verify by holding the barrel and inserting a round by hand at an upwards angle and see how it catches on entry. Then try a longer one and the shoulder glides it right in.

This sounds very odd to me. I have never had a failure to feed in any of 45 ACP revolvers. Does someone make a semiauto for the 45ACP?

Thanks you. I have two routes out of this, i can tighten crimp a little, which may improve my 80%ish success rate or buy something else 5hat will eat them

You still didn't answer the post I made above. OAL?

If they pass the plunk test they fit in the chamber. They all go BANG!, I presume?

What does the crimp (more or less!) have to do with feeding?

Cheers!

P.S. How many did you load up? (What's a "bunch"?) OAL?

P.P.S. That's why I love my Model of 1955: it will just about shoot anything in 45acp...

I theHad the same problem with my colt 1911. Problem......dirty brass.cleaned the brass and swish fed like lightning. hope yours is this s

I'm going to side with the not enough shoulder showing above the case mouth-maybe, keep reading. Just because the round "plunks" into the chamber doesn't mean that the round is going to make it from the magazine fully into the chamber. The 1911 feed path is a 2 cushion bank shot, not a straight drop/path.

The nose length of the bullet and the OAL can significantly affect the feed reliability. I've found the Berry 200 gr SWC needs to be 1.225 in OAL to feed and chamber (at least in my Bar-Sto barrel). OTOH, the Hornaday jacketed SWC MUST be the specified 1.245 in OAL (in any barrel) to feed reliably. What you're trying to do is make the edge of the bullet nose match the ogive of a 230 gr RN FMJ.

FWIW, the shoulder to nose flat on the Berry is about 0.265 in, the Hornady 0.300 in.

If the case mouth is not crimped so as to completely remove the bell that was applied for bullet seating, the prominent edge of the case mouth can get hung on the bottom edge of the feed ramp in a standard 1911. It can also grab the edges on either side of the chamber entrance on barrels that have an integral feed ramp.

FTF's ... the first thing to check is the primer seating .

Primers must be seated all the way down into the bottom of the primer pocket ... If not , the first blow doesn't fire the primer , it simply drives it into the pocket without firing ... check your primer seating .
Remember ...seat them untill they hit bottom ...if not you will get mysterious FTF's ... Trust Me on this one !!!

#1: Well, I hardly "bell" ANY cases in any calibers, so removing the trumpet at the rim is not an issue for me. IMHO improper case (over)expansion is the root cause of many (if not most?) feeding and firing issues. So is attempting to correct it (crimping issues)...

Flaring the case to accept various bullets is, of course, significantly more difficult when using lead (coated or not) in semi-automatics, even more so when using SWCs.

Much easier with jacketed, plated & RN bullets. Some 1911s won't feed JHPs reliably!

#2: The OP's F(ailure)T(o) F(eed) is probably not primer related...?

Cheers!
