    I bought this mold at a gun show thinking it would be fun to try.
    Now I can't find load data in any of my books, and not even online.
    The bullet is a cast 240 grain semi-wad cutter. Weighed to confirm the weight. I prefer to use Trail Boss because I have five pounds of it. But also have several other powders on hand.
    Anybody load a 240 for a Colt SAA before?

    No sir, never have but, starting data for 250-255 gr. should work fine.

    While I haven't tried it, loading Trail Boss can be done "by eye". I just now googled "Trail Boss loading" and found a way to load without load data, but I don't want to post it here. It deals with bullet depth and filling w/o weighing...

    I just shot a bunch of 250 gr Berry's plated with 6 & 7 gr of Trailboss. It worked fine.

    Can't say much about either Trail Boss powder OR the 240 grain bullet. I load both the 250 grain and the 255 grain cast SWC bullets in that caliber, and only use Unique powder (Unique has been one of the most popular time-proven powders for .45 Colt EVER).

    No criticism meant here - just saying how I see it: You have a cartridge that's been around for over 100 years and has enormous popularity because of it's performance. When it has worked so well for so long - why monkey around with different components (especially powders)? Having said that, a 240 grain bullet just might be dandy for plinking/practice.

    Hodgon did list the "formula" for calculating a load for Trail Boss. It's pretty straight forward!

    I can't imagine getting in too much trouble using data for a bullet that is just slightly heavier than the one you want to use. I would hesitate to do it the other way around.

    I use a lot of Trail Boss in 45 Colt for Cowboy shooting. I have to load them to the max given in the powder maker's manual for Trail Boss if I am going to shoot them in my Marlin rifle since I get a bit of blowback with the lighter loads. I use Unique for the heftier loads I carry into the field.

    Actually TrailBoss was invented specifically for 45 Colt. The cartridge was originally black powder. While there is a massive variety of fine powders to choose from, most of them leave quite a bit of air space in the loaded round. TB gets around this by shaping the powder like little donuts. That way less powder takes up more space, filling that cavernous case better.
    It's a great powder for reduced loads in just about any caliber.

    I forgot about that!
    I actually used that method once when I couldn't find data for 380/200.
    Reduced power on an already anemic round wasn't so great. :D
    The accuracy out of my Enfield revolver was outstanding. But I actually ended up with bullet stuck in my self sealing gong target.

    Isn't the 380/200 basically the same as 38 S&W?

    Yep. Just with a 200 grain bullet. Doesn't leave a lot of room for powder.

    Trail Boss is a good powder for light loads and for shooting old cartridges in old firearms. I have a few loads worked up with it but it isn't worth spit in BP Express double rifles. 'Course a lot of other powders aren't worth spit in them either. Trail Boss doesn't generate enough velocity for the barrels to regulate. It's usually pretty accurate in each barrel but with each barrel shooting separate groups 6 to 10 inches apart it isn't much good.

    Use the 250gr listed load, you will be good.

    As it turns out, load data really doesn't matter.
    After three tries, I can't pan lube these lousy bullets. I have no idea why. I cast 250 grain lrnfp using the same alloy, the same lube, and have never had a problem. I think I just found out why this mold was such a deal at the gun show. I've been burned.
    That mold is a paper weight now. :mad:

    Sounds like a perfect candidate for powder coating.
