As info, the 125 gr cowboy bullet using Trail Boss makes a great practice round. Lots of fluffy powder in the case and low recoil. A fun powder to shoot.
Thanks guys, I called the guy who makes them and he advised me to use 4.6 gn Unique. I am using small pistol mag primers because I couldn't find regular small pistol primers. Four hundred down and three hundred to go... In case you are interested Tomiswho, this is the bullet I am using, http://lonetreebullet.com/38Cal.html Out of curiosity Contender, how much Unique do you use to load your 125gr's?
Thanks for the info contender. It was difficult to find info for such a small bullet and I ended up getting it from the guy who owns the company. It sounds like 4.6 will be fine.
