Hac,

I'm using the Winchester el-cheapo Silver box 150 gr. PSP. They shoot < 1" @ 100 yds, like the RPs do for H2OBug. I was using them to break in the barrel also; but alas, they shot as well as my handloads. Have taken bunches of whitetails, and antelope at ranges from 35 yds, to 220 yds. The average price at Wally world, $16
