Resizing M1 ammo

Another M1 question for those of you who shoot and reload them. Is it neccessary to crimp the bullets for the M1

I have never had a problem with needing small base dies for my m1. I use rcbs dies in my rockchucker and everything is fine. All chamber and fire just right. I do crimp with a lee factory crimp die. It's not a firm crimp, rather light but really just to make me feel better. I have always crimped them, so I don't know what happens if you don't. An old reloader told me if the military does it to them, that you can't really mess them up by doing it too. With my m1, I am only concerned with getting minute of coyote instead of 1/4 moa.

Bob,
How they do on target as groups went?

To be on the safe side. if it was me, I would use a small base sizing die.

I use small-based dies on my .308 now, only because I have to.  I bought a Remington version of a DPMS 308 AR.  (Obviously made to spec for Remington as an accurate "hunting" rifle.

My experience was interesting......I bought 2 boxes of commercial ammo for starters, to see how it would shoot.  Remington Core-Lokt, and Federal blue box.  Not surprisingly the Remington ammo fed like water.  The federal factory blue box, unfortunately, did not.  It went bang, jam....yup...1 round and a jam, repeat.  Bolt would not close on the second one......retried for an hour.  Examination revealed that the shoulder length was fine, bullet length was fine, but the base was on the tight side.  (this was NEW ammo)  So...I thought if factory Federal wouldn't feed well, full-length conventional sizers would give it trouble......and it did.

So I bought a small-base sizer  and the reloaded ammo fed just as well as factory Remington. 

Now then, this was an exception!  1. You wouldn't have a hunting rifle's smallish and accuratized barrel and chamber on an M1 Garrand unless it was rebarreled that way.  Not likely.  2.  The generous chambers in Military rifles are generous to feed anything the soldier may have pick up off the ground.....the Remington R25 was not made to be a military clone...its a hunting rifle and is accurate as hell.  (the ONLY reason I didn't take it back, screaming)

Bottom line?  I would be VERY surprised if you couldn't use regular dies.

To be honest, I would have bought a regular military style DPMS and not the "Remington Hunters Special", had there been one for sale that month!  It was a "selfie" Christmas Present a week or so after Obama got elected the first time.......I had no idea there had been a panic run on AR's of all kinds following election day.  By the time I was looking for my AR....the only one in town was the "commercial" Remington R25.   (Christmas was scrooged.....except.....well it was very purty in its camo jacket. )
