I am getting through with a batch of 9mm ammo that I loaded with cast boolits I molded and resized in my lee sizing die (.356") The loads tumble as close as 5 yards from the muzzle.
I used ww ingots to mold those boolits, so I am fairly certain the alloy is not too hard for the load. I have not checked with a hardness tester.
In an effort to get a consitent flight, I am considering enlarging my sizer die by 0.001" to make it .357"
Am I off base doing this?
If I decide to do this, anyone have any suggestions on how to do it with hand tools?
