Does anyone run any reduced recoil loads for a 500 S&W? I know Trail Boss would be ideal, but any other powders? Don't say TiteGroup, as that one is a no-no from several shooters.

Id probably try some of the titegroup loads hodgdon has listed

5744 could be your ticket. It can work well in bottle neck cartridges and straight walled cases. i have used it in reduced loads for a few bottle necked cartridges and in some 45-70 loads.

Mostly what i load for these days with it are in the 357 Max full power loads for the Ruger stretch Blackhawk. I have pretty much duplicated 44spcl loads in 44 mag with it come to think of it.

I actually use Tite Group and wouldn't be caught dead with Trail Boss in my locker. I have used 5744 for 7.62X39 and cast bullets. It's intriguing why someone wants a reduced .500 load.

Why no trail boss?

Because it's fluffy and light, costs a lot more than anything else for pistol,, and it's for mouse fart loads I have no use for. Standard load levels in .45 Colt are the mildest I've loaded and I didn't have to resort to the Trail Boss gimmick to get there. I got rid of most of my .38 Special stuff when my .38-only revolver disappeared and I never have owned a .429 magnum nor would ever own a .429 Special. If I want no recoil I shoot rimfire. To each his own.

Someone is cranky after losing that hour of sleep because of time change

Might try to duplicate Buffalo Bore's 500 jrh load. 440 grain bullet at 950fps. The jrh brass should work in the 500 s&w. I've used blue dot in my jrh loads also. You can trim some 500 s&w brass to jrh length. Look on single action forum also for load data on the jrh and 500 s&w.

I have not tried any reduced loads. I would start with Unique or 2400 if I were going to try loading down. Lyman #4 manual has some data for both.

I have no idea what the availability might be, but have you looked at VV Tin Star? It might do what you want---if you can get it.

Between 1350fps and 2100fps there is no increase in penetration. If you want to better killing/penetrating load then you go up on the bullet weight. Simply trying to make something go faster for the sake of going faster If you're hunting with it is pointless. I have done a bunch of handgun hunting and have never felt that my 357mag, 41mag, 44spl, 44mag, or 45 Colt loads were lacking and never even considered a 500. I do have a few handguns chambered in 454 casull but I don't recall having ever hunted with them.

I didn't say speed up. I said I have no reason to slow down.
