crimp rifle rounds?

[bigchis]

I am just getting into reloading for my rifles and the reloading manuals I have read aren't real clear as to what rounds need to be crimped or not. I am reloading 5.56 for my ar, 22-250 for a bolt action remington 700, and .308 for a semi-auto rifle. I have looked at several reloading manuals and they leave it pretty open and I don't want to screw anything up. thanks.

i dont crimp any of those rounds. with bottle neck cartriges i crimp tube feed guns like the 30-30. i know some folks crimp rds for a ar but i dont.

Thanks, I was getting a little frustrated that the reloading manuals wouldn't say for sure . I knew I could count on getting good info from this site.

WhenI do crimp rifle rounds (usually for an AR), I use a Lee Factory Crimp Die.

 

[Yeah]

Never crimped any of the above.

Run 0.003" neck tension and you'll have nothing to worry about.

as i stated before i do crimp my 30-30. when im doing it i wonder if its really nessessary. it is out of a tube feed is why i do it. any thoughts

+1 too. If properly sized, the neck tension from the case will hold the bullet in place during loading into a magazine, as well as chambering and firing.

Depends on the type of bullet. I don't crimp boat-tailed bullets unless they have a groove for that (ie FMJ). No reason to spoil the aero-dynamics of a superb Sierra Match-King. On the other hand, if your using flat based bullets and need to flare the neck, you'll need to crimp them. It's already been mentioned about crimping bullets, to be loaded into a tubular magazine in order to prevent recoil from pushing them deeper into the case. For the same reason DONT use pointy bullets in a tubular mag either, or they might act like firing pins!

Any round being fired from either a cylinder or a tubular magazine MUST have a crimp to prevent bullet setback / cartridge elongation from recoil.

I called Sierra bullet tech for the same ?....they said it was not necessary...its a military thing. You can call and ask those guys anything!!!

I must be weird, I do a light crimp on all my AR loads.

I am loading a flat based 55gr v-max bullet for my 22-250. Not sure if this is a good bullet for this gun but I am trying it. I did not flare the case mouth. Maybe I should have flared them, but they seemed to seat in ok without any problems.

That makes two of us

I've never flared a bottleneck rifle round - you did fine.

Chamfer yes flare no.

Hornady makes a lot of good bullets and the 55 vmax is all right. I'd rather use the 50 as it has wee less bearing surface.

Just started reloading rifle a couple years ago. I've loaded about two thousand Hornady boat-tails in 223 so far, never crimped a one, and never had an issue.
