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.
