sr 7625
 

Hi all,

I have been loading 7625 in 12g AA/HS, STS, Nitro, and GC hulls with the CB 1078clone (21 grains) and Win 209 primers. This breaks clays when I am on, but burns very dirty. Would a hotter primer (Federal 209) burn cleaner? Or should I use a cleaner burning powder (any suggestions). The low pressure and recoil are great on this old SxS (Parker GH/Smith Grade 3), not to mention my shoulder and I have no problem cleaning after each shoot but for some reason I tend to associate this residue with an inefficient load, although it came from the Hogdon's site. All advice and recommendations are greatly appreciated.

Thanks,
john

I use IMR 7625 and it is dirty but I use it for my 44 MAG target loads so I don't have all this powder laying around. And for special effects, I like the smoke when you pull the spent shells from the chamber.....

IMR powder PB is a good choice and burns much cleaner. As for going to a hotter primer, I would be careful regarding higher pressures than a dirty barrel.

I always refer to the powder manufacturer's load data and I refer to it quite often matching all the components to ensure safe pressures for my old guns.

7625 seems to be dirty if I am shooting light payloads. I shot some 7/8 with alot of powder residue left. Upped it to 1 oz. and the dirty problem got lots better. I tend to agree that it is a sign of an inefficient load. Dave

I have used SR 7625 for years in my 16 gauge and 12 gauge light loads. When it became a little hard to find around here I switched to PB and found it to be a much cleaner burning powder. As Frank stated be careful about substituting different primers as the effect pressure.I use Winchesters to good effect.

I've used 800X a lot, and it also is dirty, but the reduced recoil and (in my opinion) better patterns make the inconveience of a dirty barrel worth it,

I've found Clays to be one of the cleanest burning for low pressure loads. Here's two of my favorites.

Federal paper hull
Win. 209 primer
1 oz magnum shot
windjammer wad
18 gr clays powder
5800 psi, 1180 fps

Rem gun club or STS hull
Win 209 primer
1 oz magnum shot
Rem TGT12 wad
16.3 Clays powder
6500 psi, 1125 fps

I agree Robert. Clays is extremely clean and soft shooting. 16.7gr. pushing a WWSL pink [1oz] wad, WW209, 7/8oz. in either a AA, STS or Gun club or Cheddite. Shoot it all day and you'll never shoot anything else.

i agree too clays is a very clean burn and soft on gun and shoulder...i load the ten ga some time with clays and 1 ounce shot 6 point crimp....this load fires good in cold wather good too.... charlie

I want to thank you all for the advice and recommednations.

I like 700X - used it in the 1970's for trap, and now for all my target shooting. A year or two ago I used PB - very clean but one of the most expensive powders. I now load just under 7/8oz [ in 12ga ] with Cheddite primers [ same as Win. ] - Claybuster wads, 0178 or 4100 - and from 15 to 17grs of 700X. That's good for 5600 to 7200psi - FPS goes up a bit. Most of the guys load 7/8oz in my club except for a few die hards who think you need 1 1/8oz . Paul
