Oh Boy, Oh Boy, Oh Boy.
First some CAVEATS. And some harassment. First harassment ... You must first understand we only deal in quality harassment here. None of that cheap stuff you see on other boards. Our harassment is made from the best stuff on earth. Where was I, Oh yeah,
There is No Such Thing as 45 "Long Colt." That's a term coined by some clown magazine writer some eons ago. There has only ever been "45 Colt." There have been other cartridges such as 45 government (not a 45 Colt but would chamber) and 45 Schofield.
Next. There is no need to "Break In" your revolver. All you need to do is take it out and play with it.
Unless your a Masochist, there is also no need for those big 'Ol heavy bullets. Unless you just must experience the recoil of yesteryear. I would suggest nothing heavier than 200Gr bullets. I personally like em even lighter.
I do not personally like Trailboss. The stuff doesn't play real well with petroleum based lubricants and by comparison, shoots a little dirty. My favorite in all manner of .45 is Tightgroup. Some don't like it because of it's "bark." It also meters superbly. You may also wish to try Cowboy 45 Special cases. Cute little short jobbers perfect for reduced loads.
NEVER. EVER. Shop for reload data on any Web Site, Forum, Board or any of that. Get a real good loading Manuel and get your load data from trusted sources that have thorough scientific testing of their data. I have seen load data presented that caused my hair and toes to curl. If using Tightgroup, a visit to Hodgden's web data is a great idea. If you can't find load data for a particular powder in your Cartridge/Bullet combo, you probably shouldn't be trying to load it??
Working up load is fun. I see no reason not work up loads for all the 45 cartridges you gun will chamber. ANOTHER CAVEAT: Your Schofield is not a Smith M-29. Approach any listed Max load data with caution.
I return you to our normally scheduled programming
