I have a Colt and USFA both 5.5 inch barrels. Bullet is about same weight as a 38, load l use 2.3 Trail Boss, feels about same under match conditions as Ruger 38s. The best load is full case of 2F with a big lube 115g bullet.
If I ever learn how to shoot with two hands on one revolver , I would use them more often.
