Years back I purchased a 7.5" barreled Bisley, in .45 Colt. It was moderately accurate, capable of firing +P loads- but wasn't "ideal" for me. I did some research on +P .45 Colt, primarily reading John Linebaughs articles. One of the relatively obscure, but exceptionally talented smiths that works on (among other firearms) Ruger Single Actions is Ben Forkin. I sent my Bisely, along with a spare .44 magnum cylinder to Ben with a line item punch list of desired work. Barrel was to be cut to 5.5" making it "handier". Sight removed and reattached. .44 mag cylinder was to be fitted to frame and line bored to tight/"match" .45 Colt chambering. Bowen "Rough Country" Adjustable RS installed. Belt Mountain Base Pin installed. Trigger Job. Re-blue. I installed Grasshorn Elk grips. I worked up a load using Beartooth 300 gr. WFNGC bullets, using H110. The velocity is right at 1300 FPS. It is a stout load capable of crazy deep penetration. This load shoots into 2" at 50 yds, but requires a lot of concentration/focus on my part. The recoil is noticeable. Feral hog I took in Southern Ok. that went over 400 lbs.
