45ACP Reloads hanging up during slide cycle

never had to trim any of my pistol brass

^^ Same here ^^
Loaded thousands of 9mm, .40 and .45
Have yet to even worry about case length never mind actually trim any brass..

Well thank you folks for all of your help. I checked the OAL and found it averaged 1.245". I will try the Kerplunk test today and make sure they sit in the right position of the barrel. You were all of great help!!! Much appreciated!

The bullet seating die core needs to be slackened off and move the die body down until the flare is crimped back in. Then you set the bullet seating depth with the core adjustment.
If it is a new gun oil the crap out of it because a dry gun does that as well. If it is a new gun it does need a break in period, so I run 500 rounds of factory through mine first. Car wax the loading ramp to the barrel.

SWC aren't the friendliest bullet profile for feeding. You need to play with the bullet seating depth to see if you can find a happy spot.

Like the experiences others have related: I've always found that seating the bullet deeper worked for me when trying to get SWC's feeding reliably in a 45 auto. Of course, you should reduce your powder charge a bit when you seat your bullets deeper. As has been stated, SWC's are difficult to get feeding nicely (but not impossible). It's no coincidence that pretty much all factory ammo for autoloaders has a friendlier shape of bullet. By minimizing flaring and crimping to make your finished cartridges have nice, straight factory-like cases, and adjusting bullet seating depth, you should be able to achieve reliable functioning.

Never had luck with SWC in a 1911. Mr. Brown designed the feed for ball ammo and that was the only bullet I was able to run in my 1911's.

I stuck with the 230RN for the same reason - there always seems to be just one gun that didn't quite like SWC, usually with one or two of my random mags.

What scuttled them was the JR carbine I had at the time. It utterly Mangled anything other than RN. Lost a good bit of brass to that beast...

I have a single stage Rockchucker press "BUT" I always seat and crimp in different operations. If you don't it is very easy to cause the case to bulge

Haven't read all the other posts after getting to this one. That's likely your problem.

Get a separate taper/crimp die. I had the same issues.

 

[madcow]

A lot of reloaders need to understand, that autos need a taper crimp / factory crimp die for pistols.

 

[sdlonyer]

The issue my be a slightly oversize cast bullet and a thick walled case...had this problem with cast which were .3145 and cases that would bulge out to accomodate the extra .0005.
Lapua brass was fine with them but S&B, Fiocchi and Starline were not

I had a similar problem with my new Sig. Its either the mag spring pressure in the new mags needs some time to wear in ( it only happens to the first 3 out of 8) or it has something to do with the very slight bulge where the bullet is seated in the brass. I bought a Lee Factory Crimp Die and ran 200 rounds through it as this solved a feeding problem in my .40 S&W Beretta. I haven't been to the range yet but I will report back on how it went.

Range report: After running a bunch of the same load through the Lee Factory Crimp die I am pleased to report that the hang issue is resolved. I'm getting to be quite a fan of these dies.

 

[madcow]

Most pistol calibre are 4 die sets that include the factory.taper crimp die, if they don't go out and get one

solves most pistol feeding issues, the other is usually the OAL of the bullets.

good to hear it solved your problem
