Full Length Resize for M1?

edited February 2011 in Perry Shooter Competition Shooting and Reloading Forum
Greetings to the GB Experts...I'm a newbie here but have been shooting/reloading for a number of years. So far it's been bolt rifles and handguns for target/varmint. I've just gotten an M1 and want to reload for it. So far I have been breaking it (me) in with Greek milsurp without any problems.
I would normally full length/trim cases for an autoloader. My question is...if I'm using the reloads (target loads - not hot) in the same M1 they were last fired in, do I need to FL resize or would neck size only create any feeding problems?[?][?]

Thanks for the help.

    When I shot an M1 in competition I did an almost full length resize. The die was set to make sure they would feed and chamber 100% of the time. The die was backed off the shell holder about 1/2 turn IIRC to get positive feed and extend brass life.

    I always full length size for the M1. If you want to experiment with backing off a touch as bpost suggests, you can; but avoid neck sizing only. The last thing you want is a semi auto with a floating firing pin and a round that chambers tightly... could potentially cause a slam fire with the bolt not quite locked shut and that would really ruin your day. Or more likely just jam things up good.

    bpost & jonk,

    Thanks for the info - you both have reinforced my assumption that reloads for an autoloader should be FL resized.

    I'm using CCI milspec primers and I'm interested in maximum brass life, but not at the expense of safety.
