Shockwaves shoot excellent in most rifles. Out of my Black Diamond XR I have shot groups that measured under an inch at 100 yards. Whether I could shoot a 2" group at 200 yards... maybe with practice and a better scope on my rifle.

If the powerbelts are shooting great out of your rifle and doing the job, there is nothing wrong with trying the shockwaves. At least you have a load to fall back on if they are not accurate. I shoot shockwaves out of the Black Diamond with 110 grains of Goex FFFg. In my Knight I shoot 90 grains of FFFg. In my CVA Staghorn I shoot 90 grain of FFg. All of them shoot shockwaves very well.

Good luck with your rifle....
