I was trimming brass this weekend on my new hornady case prep center and accidentally trimmed my 300 win mag brass to "2.600 -- all 500 of them -- instead of the "2.610 trim-to length. I didn't notice until the very end when my buddy stopped by and was checking out the machine. The brass are all very consistent at ".010 short of the recommended trim-to length. My question is this...have I ruined the brass by trimming them so short, or will I just lose the ".010 worth of crimping power in the neck tension? I am primarily loading these with 165gr sierra match kings for long range target shooting. Has anyone ever done this and then loaded and shot the rounds? What were the results? Can I still get decent accuracy from these brass or should I trash them? Any comments are greatly appreciated as I am in a dilemma on whether to continue reloading the brass or not.
Here's an interesting observation on the brass:
Winchester -- Way more brittle than the other brands
Hornady -- all once fired by me and none of them needed trimmed, even at the shorter than recommended "2.600
Remington and Federal -- not much difference
