Hi, new posting member here. I joined specifically to ask a question I have not been able to answer through much googling:
Does anyone know where I can find information on muzzle velocities, either factory or handloads, for 450 BM in barrels shorter than 16"?
Edited by Hoot to stress the caliber he is interested in. Read: Not 223, not 308, etc.
BTW, Welcome Aboard.
