Title: reloading .223
Post by: 79takjr on January 17, 2009, 07:26:40 PM
Hey guys,
I got a ? about shooting .223 when the crimp allows the projectile to spin in place.  Can those be shot without too much loss in accuracy?

The projectile does not move in and out, just around. 

when reloading, about half my rounds come out with the crimp die not getting a good crimp.  Even when I adjust the die, these rounds dont want to crimp.  They already are right at the specs allowed.

Any ideas?

I wouldn't think it would, but I can't say for sure.  Give me a day or so and I will ask some folks I know who WOULD know. ;)

I got this from a buddy of mine who is a retired LEO and avid hunter.  He has reloaded most sporting and hunting calibers for years and does a lot of varmint shooting with a .223.

"Bullet turning in the case should not effect your accuracy. NOW if it is moving forward or backward in the case that is another question all together. In some caliber's such as the .223 which is a relatively high speed projectile position of the bullet just as it is to enter the barrel is an important factor in accuracy. Hope this helps."

From that, I'd say that as long as the bullet is firmly seated fore/aft then you're good to go.  That makes sense to me also considering how the cartridge seats in the chamber relative to the barrel.  As long as your overall length is consistent I'd say accuracy shouldn't be affected by that.

Just heard from another buddy who varmint hunts with .223 -- he had another suggestion for you.

"Tell him to get a Lee Factory Crimp Die.  It sounds like his neck sizing button might be a little large and is expanding the necks too much and all he's getting with a standard crimping die is just at the case mouth."

Hope that helps!
