I shot the RCBS hard cast, 28 BHN boolit with 5 gr of 231 for a silly cowboy load to max today. They have only aged a couple of days.
I shot the light load at 25 and the 296 loads at 50 yards. My .22 recoils more! That goes for the hotter loads too, what pipsqueeks!
Anyway, the first shot from a clean barrel was a little low right but the last 4 went into 1/2". I had to aim at a lower target because they hit so high.
I went from 22 to 23.5 gr of 296 at 50 yards. 23.5 opened up so 22.5 to 23 would be best.
This is about the best I ever get from a semi wadcutter, they will not match an LBT style for accuracy.
At least it shows that you can use a very hard boolit, PB, for cowboy loads and go right to a hunting load.
Whatever, this boolit will remain my plinking boolit, never my serious hunting boolit.
