I load several calibers and have no problems with any of them except .45GAP. I can't seem to get the crimp tight enough. None of my other sized rounds will ever have a bullet move even if jammed, but the 45 GAP will move if disturbed.

I use two Lee single stage loaders doing two operations for the whole run then changing the dies and doing the last two operations. I started out using my .45 acp dies and thought that was the problem, so I bought 45 GAP dies. The rounds shoot well, but again I have to be careful with them. Any suggestions would be appreciated. I'm planing on going to a turret or progressive system in the spring, but want to iron out this problem first. Thanks again.

Dave :wow:

Except for a roll crimp into a bullet designed crimping groove taper crimping will not prevent set-back.

Your problem lies not in your crimp but one, or more, other problems. The first and most obvious would be your sizing operation; die not adjusted correctly, faulty sized die, brass that is not actually brass and springs back to previous chamber size.

Another possible problem could be your bullet size. For jacketed you want .451 and for lead you want .452.

Continuing to tighten your crimp will not fix your problem... backing off the crimp until you just remove the flare/bell will actually give you better results.

What jack said. Back off on your crimp. You just want enough crimp to remove the bell. I wish they would rename taper crimp since it is not a crimp. It’s just removing the bell.
I would say that 95% of the people that bad mouth Gap have never shot one.

Thanks. I reload the Winchester brass that I bought as rounds and also bought some new Starline brass. I'll try resizing a little more and backing off on my crimp. I may have mad the bell a little too much. I use Rainier and Berry's plated bullets. Again thanks for the help.

How true this is!!

This year alone I have sold 7 .45 G.A.P.'s to people who came in wanting something else...usually .45 ACP. I will sell .45 ACP (in fact I'm doing the paper work right now and waiting for his sights to come in so I can deliver on Thursday) BUT...if they are open to it we go to the range and shoot them, side by each. The .45 G.A.P. only lost once, and I still sold one to his wife (he ended up with a PT145). My point is UB is correct. In fact, I sold 2 LnL AP's with the .45 G.A.P.s. So it's good for me. And is my EDC weapon.

So as not to hijack the thread...I agree with Jack and UB. with the term "crimp" attached to the die, one tend to think you can get a better "grip" on the projectile, when in reality, case (or neck) tension holds the projectile. So make sure the sizing die is correct.

How do you do that? You resize completely. Then you do the next step. Are you using a FCD (came in the Lee 4 Die Set)? If so Stop. Remove the flare in a separate step using the seating die and see if that helps.

Worth a try. Thanks. I will do that. Yes I do have the 4-die set. Thanks.

Stand down. Creo has been in GTR far longer than you.
Well, at least my post was relevant to reloading.

I like a group that stands up for their members.
Kinda like how I tend to defend GT low post count .45GAP owners who come here looking for a little help on a technical question.

By your response, I'm certain you understand the feeling.

Have a great day, gentlemen.

I really want to know what happens when you seat a bullet. Don't crimp it. Try and push it against the table. See if it shortens like the others that you have crimped using the FCD. Then you either have too much crimp or the FCD is sizing the round causing the issue. That would make my day. :cool: Everyone knows I am not a FCD fan.

I only own one 45 ACP anymore. All my 1911s in ACP have been converted over to GAP. My revolvers with shoot both, but I pretty much just shoot GAP.

Easy round to reload and people love giving you brass. And one less size of primer to buy.

That said, when you resize be sure to adjust the die all the way down to the shellplate/shellholder. When crimping just take the bell out and be sure there isnt any light around the case & bullet.

Just received my 600 bullets from Hornady--185 gr. XTP. Going to finish out the last of the 230 gr. 45ACP loads and then will set the dies and priming system up for GAP. Thankfully, the load manuals have the 185 XTP listed for GAP.

The only reason Hozer shoots the GAP is because ACP cases are actually taller than him. :whistling:
