Is it just me or is H110 very dirty? I shot 30 rounds yesterday and my pretty silver S & W 629 was black. Any advice?
Thanks, Kirk

Lil gun in my 44's, 45 LC's and 357's. No black crap, well, very little. A pound lasts forever.
in a 629 or a mod. 29 platform, I'd never ever use H110 powder. Too hard on the action. I like AA #9. Burns very clean and get pretty performance out of it.

youll have to explain how 110 is harder on an action then aa9. If anything the faster burning aa9 is going to beat a gun up a bit more because to get the same velocitys your going to be running higher pressures with aa9. but neither will beat up a good gun. the crud usually comes from running to low of pressure or if your using cast from the lube.
instead of arguing with me, make a quick call to Smith & Wesson. That action was never designed for that kind of pressure that most guys think they will handle. A quick look thru most of the reloading manuals will show virtually all development was dne with a Redhawk or a T/C. The handguns will take a lot more abuse than the 629/29. I started out with some H110 loads, and later tried the #9 combination with the same bullets. The #9 load was noticably milder to shoot while being a tick under 1400 fps (24.0 grains of H110 / 20.0 grains of #9 with a 240 grain bullet) I get 1380 fps with 20 grains of powder thru an 8" barrel. The H110 load in the Speer manual shows about 1450 fps. I'd say that's pretty close to what I measured. Now I do shoot the same bullet in a 12" T/C with H110, and see almost 1700 fps with some serious recoil. All I'm trying to say is that if you are going to use H110, then back the loads off a bit to reduce the pressure factor.
By the way I shoot a Lyman 250 grain cast bullet (Kieth style) with a gas check a lot with about 19.5 grains of #9. I still get slightly under 1400 fps, and the load will shoot in the inch and a half range at fifty yards without any serious effort (probably do a little better than that). Have never tried it at 100 yards as the only 44's I shoot that far are from a T/C or my .445 supermag. The #9 burns very clean, and I get very little leading in the 629, but see it in the T/C.

SAMMI listes max. CUP pressure for .44mag @ 36,000, why would S&W mafg. a handgun for less than SAMMI max. ?
the 29 platform was designed long before SAMMI ever was thought about. By the way most manuals list loads that are well in 38K+ range of pressures. Now a T/C is good for about 40K max, and your telling me that the 629 is as strong as a Contender!! A Dan Wesson, Super Blackhawk, or a Redhawk maybe, but that's about it

re read my question . how did T/C contender enter into question ? and, I wasn't aware SAMMI didn't exist before 1978, thought it was more like in the 1920's.
