I have sent my Ruger Redhawk .44 mag in to Bowen Arms for conversion into their .45 Colt Alpine model. It will return with a 4" barrel. I will be shooting the Beartooth 350 gr LCMN bullet over WW296 or H110. This will be my "pest" gun when I am boating, fishing, hunting. I hope to be able to launch the bullet out at 1200 fps, with a HEAVY but SAFE load. Any comments or suggestions?
