I load 7/8 ounce 12 gauge shells at around 1200 fps and I was wondering what your favorite powder is for loads like this. The local shops price their powder on the high end compared to what I’ve seen at out of state trap competitions so I want a powder that is cheap(er) and can get the job done with less than 18.5 grains in a AA hull. Any suggestions? I don’t care if it’s dirty because I clean my o/u after every trip to the range.
Thanks in advance.
I also load 7/8 oz in my 12s, so I know where you are coming from.
By far the best, safest and smartest way to get the answer to your question is simply to go to the on-line reloading guides for Hodgdon and Alliant.
Enter the hull you will be using and the 7/8 oz load. Then just pick the load that uses the least amount of whatever powders are available to you. Then reload according to the manufacturer’s recipe.
This isn’t a particularly original answer, but it really is the easiest way to get a good load. The powder makers have done all the work and ballistic testing for you so you might as well take advantage of it.
And good luck. 7/8 is a nice load in the 12 if you want to keep recoil down and control costs somewhat. At $40/ bag of 25# shot, a 25 round box of 7/8 oz shot shells saves 67¢ and the lower amount of powder needed saves another 10¢.
Another big saving is in recoil. In an 8# gun, free recoil with a 1-1/8 oz load at 1200 fps is 20.3 ft/lb. With a 1200 fps 7/8 oz load in the same gun, it is 13.1 ft/lb. Gotta love that. Save money and save pain.
