It is getting closer to the season here in Michigan, and once again I am falling behind. I did purchase the shim kit from CVA and was wondering what would be a good starting point to start with? .017 is what someone told me, so I thought I would ask the experts on this forum. Also CVA recommended Whitehots, 100gr. with a 270gr. powerbelt and winchester 209 primer (not triple se7en primers) SORRY, I am shooting a cva optima 50 cal. with the QRBP. one more thing. should I wet swab the barrel after every shot. I am new to bp and the pellets would be easier for me this year anyway. Any help would be appreciated. Does this sound like a good round and charge?
