Is this a good bullet for both 45 ACP and 45 Colt?

45Colt

The 45 ACPs I have are:
  • S&W 625 - This will of course shoot fine through it.
  • Springer XD-45 Tactical - I have this bullet profile in old-fashioned cast/lubed and they work fine in it
  • Cimarron P in 45 Colt - Seems like it'll work fine; I just have to decide where to crimp it. As I recall, my Lee Factory Crimp Die doesn't need a crimping cannelure.
It seems like it should be OK, but their page for 45 Colt bullets doesn't mention this bullet.
 
My guess would be that it doesn't have a crimp groove, which is usually helpful for a rimmed cartridge like the 45 Colt.
I would also venture to say that in less than full house loads it would be fine for the 45 Colt.
Bullet creep USUALLY isn't an issue in applications that aren't tube fed or rotating cylinders.

ETA: I would suggest the 45 Colt 225gr RNFP offering from that site for both your applications......

I have shot plenty of that design/weight in .45 ACP, and there is no reason you couldn't make it work in .45 Colt, just use your .45 ACP seater to taper crimp it in .45 Colt cases, or roll crimp into the unused lube groove, or seat it deep and roll crimp over the ogive
 
I tried something that looks another like that one for my 1911s and found it had issues that didn't come up with rn bullets, I think they are 200gr and shoot well in my M&Ps.

My 45 auto pistol isn't a 1911, so it's not quite as picky. (though it will NOT chamber a SWC reliably)

swc bullets are picky and usually require a thumbnail width of the shank only sticking out of the case. i shoot 265 grain lswc bullets out of my glock 30 and 1911 colt. if i don't get the col just right, the case rim catches on the feed ramp.

Thanks murf. Maybe the two times I've tried it, that was the problem. Maybe I'll try it again, as I really like SWCs.

What weight do you find works best? I've seen them ranging from 165 to 200 gr., with 185 gr. being the most common.
 
I kinda stick with what I know, so no crimp groove is a deal breaker for 45 Colt for me. Many will taper crimp and some will roll crimp into the side of the bullet. My "experiences" with those are cutting the coating (PC) will often lead to barrel leading and for larger revolver cartridges I've had bullets walk under recoil when taper crimped. But if I had some of those bullets I definitely would give them a run in a 45 ACP (I may have a mold for that bullet, and it feeds well is my 3, 45 ACP guns) and see if it will stay seated in my Cimarron 45 SSA clone...

I do have similar bullets I bought for 45 ACP, so I will make a small run of them with a roll crimp over a deep-seated bullet and see how that works.
Good point about a roll crimp biting through the plating/coating. That's probably why they don't recommend it for 45 Colt. At the level I'm loading them to, (MAYBE 900 fps) I don't expect any problems with bullets pulling out.
 
… some will roll crimp into the side of the bullet…. are cutting the coating (PC) will often lead to barrel leading and for larger revolver cartridges I've..

I think barrel rifling induces more trauma on bullet powder coating than a roll crimp. How about you?
 
Not really. I have recovered a few PCed bullets, fired into a magazine bundle and often the rifling does rub the coating off, but the bore portion is intact, no fouling. If the coating is cut before shooting, the bullet enters the barrel damaged and the coating is more prone to scraping/rubbing off. I consider the PCing a "soft jacket" and if cut or improperly applied (coating thickness, curing time) leading will probably happen...

185 and 200 are most common for target shooting. the 265 grain bullet i use is a hunting sidearm load. the col is important with all swc bullets.

p.s. the far right bullet in the post #12 pic looks like a good shaped swc bullet to use in the 45 acp chambered guns.

Depends how aggressively you roll crimp. I don't get serious with low pressure/low recoil loads. So my tool crimp is minute. On magnums with slow burning powder I be careful of where I start the crimp so it sets right without cutting the coating.
 
I agree with several of the above posts.
Buy the 225gr bullet listed for the 45 Colt because of the crimp groove and use that one for both loads. The crimp groove won't effect your 45 ACP loads since that uses a taper crimp.

I also agree the bullets from the MBC are a good alternative too.
 
I try to use bullets that come with a crimp groove when loading something that will be roll crrimped. If it will not be crimped or just taper crimped, a bullet that has a crimp groove or canalure I just ignore it. So far I have been able to find purpose made bullets and not had to go outside the box. Anyway I load .454 lead bullets in my 45 Colt ammo and .452 lead bullets in my 45 ACP ammo. I do realise that most modern firearms use .452 lead bullets now but loading for older revolvers needs to be different.This has been an interesting read nontheless.
