I've been looking for powder for my 40 and 45 for awhile locally. Finally today found some clays, not exactly what I was looking for but picked it up cause it's better than nothing. Seems like it will work fairly well with light loads in my 45 with 230 gr bullets. Unfortunately my manuals don't list much for 45s and nothing for clays for 40. My research shows "proceed with caution" in 40 s&w. Any feed back on this powder with these cartridges? I was hoping to find some Unique or Bullseye, but you got to use what you can find these days. I will probably just burn it up with practice shooting. | ||

When it comes to using shotgun powders in pistols,there are few if any that cannot be used. The only real factor is how clean it burns and will it cycle a semi-auto with safe pressures. Cast Boolits.com also has many loads you can try. Gulf of Tonkin Yacht Club NRA Endowment Member President NM MILSURPS | |||

Thanks guys, I checked out those sites. At this point I will be using jacketed or solids. Most things I've read say that clays is a pretty clean burning powder. I will give it a try, starting with the 45, because I haven't found any small primers yet for 40. The data shows a very steep pressure climb with this powder in the 40, definitely one to be careful with. Loading for 45s in 1911s, the 40 is a Glock. | |||

Why not just go to the source ? http://www.hodgdonreloading.com/ Hodgdon Universal Clays is pretty hot stuff. It ranks #58 on the burn rate chart containing 240 entries. Unfortunately Clays isn't listed in my internal ballistics software so I can't run off any data. But Hodgdon is showing some loads as low as 3 grains. Obviously that means "look out". Weigh and check! | |||

HEADS UP: Achtung! Don't know what happened with my internal ballistics software but true to my character, I went back and checked again then again. Either I was too superficial or the program has tricks that I haven't mastered yet. But --- I found Hodgdon Clays. In the 40 S&W it isn't dynamite - it's nitroglycerin dangerous. I got results with 5 grains up to 52,000 psi red lined and warned DO NOT LOAD. I got results with 4 grains up to 32,000 psi. I got results with 3 grains OK, good to go. This is a powder that will mean 10,000 psi per grain !!!!! Absolutely mandatory to exercise prudent caution when loading and measuring. My impression it that the Guys here on this forum are, for the most part, VERY experienced veterans who know the ropes and use commonsense. That combo that we speak to is in the lower supercritical area that needs very careful attention. | |||

Nmiller, I picked up a Keg of Clays (Not Universal or International) from one of our IPSC shooters who had gotten it for loading his 40 S&W. He had followed the published data on the canister and ended up loosing an expensive magazine and some other parts (thankfully that was all). Personally, it is too hot for the 40 for me. Now I have used it in the 45 and do use it in my 38spl cowboy action loads. The thing is, the 38 loads are low to moderate velocity with lighter cast bullets to save on target damage and for economics. I would be patient and keep looking for one of the better powders.

Well, Hodgdon does show loads for the 40 S&W with Clays??!! | |||

The problem with Clays in 45 ACP is that you will more than likely end up using only about 50-60% of the case capacity to achieve a reasonable velocity. Clays is position sensitive in the brass, meaning that you will get inconsistent results with a round with the powder sitting on the primer (hold the muzzle vertical, then lower the barrel and fire), compared to starting from a draw (with no powder on the primer) and then moving the barrel upward towards the target. Clays is too hot a powder to get the requisite load density for consistent ignition. I would be very careful with it. | |||
