Does anyone shoot any of the Pedersoli BP doubles in any of the calibers here? I've been trying to come up with a double that I won't have to sell my soul to finance and Cabelas sells these for around $800 which I can afford. I'm thinking either .50 or .72, my concern is will the .72 stabilize conicals or is it a ball only gun? What kinds of velocities are you getting with what bullet weights? Thanks.
