Great Choice!! I've been through there many times, usually just going through, but there was a guy I dealt with there at the Powder Horn - he made some great bullet lube. I bought some bullets from him way back before I was casting, and I shot an antelope buck with one of his out of my Blackhawk 41mag. A picture is posted on his info board at the shop. Haven't seen him in over 7 years and don't know if he's still in business. The motel is on the right going into town from down south (ie coming from Green River). Might be through there late this summer or early fall, as I'm planning a trip through Cody to Green River and then Denver or something like that.
My records show a lot of 29.5gr of H335 with a Lee 176gr Cast bullet and some 30gr of H335 with the same bullet. These were loaded for friends of mine and I never saw them perform, but one of my friends began loading his own and really like them enough to duplicate them. Another claimed he hit the 500 meter gong at the range on every shot....well....not sure I really believe that, but he asked for more of them everytime he ran out. At the time it was the only 30 caliber mold I had. I now have a Lyman #311411 I think it is that casts at 183gr with my wheel weights - I run the same loads as with the Lee without issues. Again, I don't use these in a 30-30 as I don't have one - I make these for friends and family. I do use them in my Dad's 30-06 and he loves them.
