If you recall, I miked my 147 gr FMJBT bulk bullets and found most were below .308 dia. , usually .307.
I fired two 10-rd groups from a sandbag, one with bullets selected to be .3075-.308, the other randomly selected bullets, loads otherwise identical: 748/49.5/F215 primer. No crimp.

Selected bullets grouped 4". Unslelected grouped 7". Both loads show lots of soot on the brass.

So now I think I got poor bullets. Live and learn. Next, I try crimping. Is crimping standard for M1? I'v never crimped any of my centerfire rifle loads, but they've all been for bolts or single shots. And if I crimp, I figure I should reduce the load a couple grains. Agree?
