A CVA was my first ML I only shoot 90 gr out of it and you have to experiment with bullets everygun likes a different one. The front site on mine was crap also. It cost me a 10 point at 20 yards!! moved in the truck. then a gun smith told me the clear nail polish trick. never happen again. well to the point I killed a lot of deer with my CVA and you should too.

Oh one last thing Clean IT OFTEN!!! A month on mine is too long. IT LOVES TO RUST!!
