This is the route I took some years ago to get into muzzleloading. I found cheap is good in muzzleloading. I have had great success with my CVA.
Accuracy is fine. Cleanup is not the disaster some would have you believe.
I use (2) 50 gr pyrodex pellets and the .295gr Powerbelts that came with the rifle. I hunt no more than 5 times a year with this setup. As a 40 year rifle hunter, was stunned by the accuracy. This is not primative, but very enjoyable to pull the trigger, and feel confident!!!
