There is difference in felt recoil between Trail Boss and most other powders. TB feels softer, even though it's a fast powder. I use it in all cowboy loads for 38Sp, 44Sp, 45 Cowboy Sp, and 45LC, including 45 acp; and a 45-70 trapdoor for targets at and under 100 yds. Also in 7.5x55 Swiss. For other reduced loads in other military rifles, IMR 4064 and Alliant 2400 (carefully), sometimes Red Dot. For 9mm and 40 S&W, Clays, Power Pistol, or Bullseye, some Titegroup for Super 38. Probably should have settled on Unique for pistols and may life simple (and cheaper).
