Thompason Center claims if your rifle is the XR model, you can shoot three pellets (notice I did not say 150 grains of loose) and the 250 grain Shockwave and get excellent accuracy. I found 120 grains of the loose and after that it starts to spread a little more.

I bought a box of the 300 & 250 grain Hornady XTP's also. I am going to shoot them in some of the different sabots and see what kind of accuracy I can get.

I took the Staghorn out this morning and was shooting LEE 320 grain R.E.A.L.s at the 50 yard line with open sights. I had shots touching each other using 80 grains of Triple Se7en, so I was more then happy.

My Wolverine II and my .58 caliber did not make it here friday, the guys in the little brown truck down come this far back into the woods everyday. So I will have to wait until Monday for it...

Good luck with your rifle. I am sure you will like the Shockwaves.
