I just switched to blackhorn powder after reading alot of good things about it. but after a day at the range iam wondering if i made a mistake. iam shooting a cva wolf the older one without the QRPB. replaced the the breech plug for one to use with the blackhorn 209 powder. shooting a 250grain shockwaves. and can not get it to group. tryed useing 90 grain and worked up to110grain of powder, still dont group very well they are all over the place. but i went back to useing pellets and shoot 1"2" groups again.at 100 yards so what the hell? thought that stuff was suppose to be better than t7 pellets? or is it just the gun. likes one more than the other? just pisses me off i spent the extra money for something that dont work. any help please. thanks chuck.
