I HIGHLY suggest you do NOT use 3 pellet loads. The MAX powder charge is 110 grains of the old CVA's. Over charging the barrel can cause it to burst in your face. Please get the rifles info before someone gets hurt or killed.
I agree!!!!!!!!!! WAY TOO MUCH POWDER!!!!!!!!!
I'd recommend loose powder and start with a light load (I like to start around 70 or 80 grains) then work up checking for loss in accuracy or any signs of excessive pressure (like blowing caps off the nipple).
