I fired these in a 30-caliber Saginaw carbine. There is quite a difference in case capacity, the 30-caliber having more volume. 10-11 grains of #7 leaves a lot of space in the 7.62 x 33 case, but there seems to be no ill-effects and it shot very clean.
I have as much #7 as I do anything else and it is good to know it will work. I will get around to doing some accuracy and chrono work in a few days, but I doubt very seriously that I am pushing 2,000fps.
