do you need to crimp on 30 carbine?

[duggaboy]

Well, I just got the dies for the 30 carbine and now I am thinkng to myself, do I need to crimp the case or whatever crimp means to secure the bullet enough to function well in the semi auto type mode? Is this the correct thinking? How about the garand? or the MIa?thanks , duggaboy

no need for me to crimp. Can actually see the bullet base after seating.
using USGI brass.

[Sunray]

No. Where'd I see this question before?

[bigbore44]

The standard GI 30 caliber 110 gr bullet for the 30 Carbine doesnt have any crimping groove on the bullet and military issue Carbine ball ammo is not crimped. That should be a clue. I never crimp my 30 Carbine reloads. For that matter I usually dont crimp reloads for 308 or 30-06 either. One round I do crimp however is 30-30 because its used in a tubular magazine.

dosen't the carbine round headspace off the case mouth?

[us019255]

I have always crimped 30 Carbine, 9 mm, 45 ACP etc. that crimp on the case mouth. I am careful to only taper, or collet (factory) crimp just enough to see under magnification that the mouth of the case is just a smidgen smaller than the body.

If I inertia pull a bullet I can just see a deformation where the case bit into the bullet.

Knowing that the bullet is a bit more secure, helps me sleep at night.

By the way, I have examined carefully rounds that have been in pistol mags. for repeated chambering and never seen any evidence of the dreaded bullet set back.

PS. I am aware of the admonishments against using reloads for defensive purposes and have chosen to ignore this since the pistols in question are carried for defense against 4 footed predators who are unlikely to sue me.

In a recent (couple of years) murder trial, the defendent, who was obviously defending himself from an attack by a local man known for violent outbursts, was convicted of murder because he used hollow point bullets "made to kill". Interviews with the jury, mostly women, after the trial indicated the deciding factor of guilt was his use of hollow point bullets. No joke. True story.

The defendent got 15 years in prison.

I sat very still for a long time trying to grasp the stupidity of that jury. The jurors agreed it was self defense, but decided it was murder because of the design of the commercial rounds the defendent used (10mm rounds). The defendent had a carry permit and was about fifty years old without so much as a traffic ticket.

The program was "24 Hours Hard Evidence". You can probably find it online.

It isn't just reloads that will get you into trouble, and a lot of it.
