No need for me to shoot at smaller targets. My M1 with a 60 year old barrel will shoot a little under 3" groups (8-round) at 100yds from the bench. Groups will go down to around 2" with 168BTHP rounds.
The M1 was never designed to be a target or sniper rifle. Yes, it can shoot far better groups with newer barrels, bedding, National Match parts, etc..but the standrd M1 was meant to be shot at man sized targets, which is what I was doing.
I haven't shot in the sitting or kneeling position since my days in the USMC, and I just wanted to see how I'd do. More range time from those positions and the groups would look even better I'm sure.
I'll be trying to make it to a 200yd range on my next outing, plus there is a 300-400yd range that I'm planning on getting to as well.
