Apparently that’s a custom job from the guys at Bowen
I’ve been getting a serious hankering to stoke my 45 Colt Redhawk for awhile now. According to John Linebaugh in a Ruget it is a pice of cake to duplicate 44 magnum velocities. For a 250-ish grain bullet, the 44 mag runs around 1400 ft/second. I don’t need that much according to Linebaugh - he and his sons are dumping Mule Deer with 260’s going at 900 ft/sec.
Some guys get trapped into the bigger-better-faster ego trips but I am not one of them. I seek efficiency and power that I can’t use is a waste.
If you are a 45 Colt guy as I am… there is some fine reading to be had here.
