I would use the bonded 250gr shockwaves out of your prohunter, dont use the yellow tipped shockwaves (or atleast i will never use them again). Try this load- 250gr bonded shockwave, 105 gr of blackhorn 209 with winchester 209's.This load produces less than 1 inch 3 shot groups at 100 yards for us and the blackhorn 209 is very consistent and you wont have to swab the barrell but after 8-10 shots!The shockwave will load very easy in your prohunter aswell!Good luck!
