I have been loading 240 gr Hornady XTP with 28.6 gr of IMR4227 in my AGS. The gun used in testing was a VH8, should I be adjusting down in powder weight for a shorter barrel or does it matter? It seems as if there's a lot of powder left over and my shroud got stuck after only 50 rounds. I clean every time I shoot so I'm wondering if you guys with more experience know which of these burns cleaner or where I should look for more load info on the 445. The new Hornady and the 5th Ed. Sierra list W296 & W680, H4227(recalled and can't find it) & H110, AA1680 & AA5744, & the only one I could get at a local store, IMR 4227. I live where there is only 1 store with not much in Wyoming so I'll have to get it on the net.

Hey partner,
I saw your post, so thought I would comment. You know I've not shot my SM yet, but I've hand loaded the 222 Swift, 25/285, 7 Mag, 338WM, 458 WM, 357, 475 Wildey, 50 BMG plus a few more. I wouldn't reduce your load, unless you want a reduction in V, plus some powders shouldn't be reduced more than 10% from recommended pressures. You'll need a powder that burns cleaner in a short barrel.
I found a comment by Grant Cunningham, and maybe this will help.
' For all-around use in a wide variety of pistol cartridges I really like Hodgdon Universal Clays. It is extremely clean (the cleanest I've yet used) and is useful in a large number of calibers. My only complaint is that is isn't suitable for light loads in spacious cases, because it often fails to burn fully. This results in lots of unburnedpowder flakes that always seem to end up under the extractor. I'd like to find an equivalent powder that is more suitable for light loads, but haven't found it yet.
For magnum cartridges, I like Alliant Blue Dot. It is very consistent, burns cleanly, and gives superb velocities. I've used it in the .357 Magnum, the .44 Magnum, the fire-breathing .445 SuperMag, and the obscure .451 Detonics Magnum. In each case it performed superbly. So pleased am I with Blue Dot that one of these days I plan to try some of the other "Dot" powders.'
Hope this helps.....
