The CVA Bobcat is a very capable firearm. See my post from yesterday titled "Ready for Elk season." That is a pretty stout load. Recommendation - don't shoot over 80 grains powder with more than a 300 grain bullet, you WILL feel it. I have also found it doesn't like sabots very well, but will shoot conicals and round balls just fine. Also, I have done "powder burn tests" and after 80 grains with round balls, not all of the powder gets burned anyway, so I have found it is best to keep the powder charges under max for the best powder efficiency. Good luck, stay safe, and have fun!!
