Hi im new to this forum
Just wondering why when i search to find out if factory federal american eagle 168 gr otm (m1a on the box) has the bullet crimped?and if so, what type of crimp they use? I always seemed to be directed to talk about peoples opinions when all i really want to know is WHAT THE FACTORY Actually DOES. Peoples opinion about semi auto yes, and bolt gun no, are just opinions.looking for real facts on this . THANKS TO ANYONE With Real Info for the Infoloader lol... THANKS.....

I doubt it is crimped. Ask Federal. I hope it's not.

The best 30 caliber match ammo has no crimp as that degrades accuracy. Either Arsenal nor commercial that shoots the best scores in semiauto service rifles.

Appreciate the response. I just want to load it the way the factory does, or at least as close as possible.
Also wandering if nato brass is different from fc brass like american eagle 168 gr otm7.62 (m1a). I thought maybe its more like commercial brass 308. Even though its loaded for 7.62x51.ive read alot about quote "NATO BRASS", Being different in case volume, so i wasnt sure if fed ae168gr otm m1a use 308 brass or nato thicker brass for their factory loads. THANKS TO ANYONE WITH GOOD INFO for the Infoloader lol....

Federal makes their own brass so they use it

Surplus military brass is plentiful, but the worst choice if best accuracy is first on your priority list. It's thicker and more durable so it's better for combat. It can be reloaded with a grain or two less powder as there's a tiny bit less room inside.

I still have a part of a box of the Gold Medal Match .308 with 168s and it's not crimped. I am with Bart, I doubt the federal american eagle 168 gr otm is crimped.

Maybe someone has some and can answer you for sure.

Federal's web site picture of that ammo shows a bullet with a knurled in cannelure. That alone unbalances bullets.

Neither has a crimp of any kind, no taper or roll. I've been reloading for M1A rifles for several decades and I feel that crimps are of little or no value. I've read of some people claiming more consistent muzzle velocities but I've never seen it. I think it depends on the brass, the bullet, your equipment, and your technique. The more precise you are in your reloading process the less value crimping is. As far as the perception that crimping can help accuracy, I believe that it simply compensates for poor cartridge construction, it helps overcome bullet total runout which is more correctly minimized by using good parts and proper assembly procedures. Personally I've never crimped and my precision ammo does quite well, I've made shots out to 1100 yards and was satisfied with the performance of my ammo - of course everybody has their own definition of what precision is so your expectations might be different then mine.

I know why folks who crimp bullets in case necks have no interest in learning and understanding why those that don't crimp shoot bullets the straightest with functional reliability and best accuracy and precision. So does many others who don't crimp.
