Good morning, Gentlemen! I've been working with an 1899 Krag carbine (actually it's a cut down rifle, with an 1899 stock), and discovered I couldn't hit anything with it. I'm talking to the extent not all rounds would be on an 8.5 x 11 sheet of paper at twenty five yards level of bad. I've always sized my Krag bullets to .309, so I decided to try .311 since I had that sizer die. Groups (just leaning over the pickup tool box for a rest) went from 6-8" to about 1 1/2 - 2". I guarantee they'll be better with sight black and a proper rest, but at least now it seems I won't have to re-barrel to get it to shoot.
What are you other Krag guys doing for bullet size on your rifles? I've never had that dramatic an improvement on any other rifle just by changing the bullet sizing. Learn something new all the time!
