RST powder in their lite 2 7/8" 10 ga.

Bill, seems we have a difference of opnion. My IMR reloaders guide is from 2004 and in it for every powder there are 4 different powder loads when useing the same of everything else. They change 3 to 4 grains with velocity and pressures going up or down. With 21grs of PB - Rem primer - CB-1100 wad and 1 oz of shot the pressure is 3800 at 1100fps. Up that to 25grs and we get 5600psi and 1250FPS. I don't think 7500PSI is a really low pressure load that couldn't be taken down a bit. I haven't shot the one quoted earlier, but I have to believe there's a bit of felt recoil. If useing all the same components and powder is reduced a grain or two the velocity/pressure/ and recoil will go down. I noticed Alliant doesn't give more than one formula per load so I emailed them. Let everyone know what their reply is. Paul

Paul, I'm not implying that I wouldn't reduce the powder charge of a 7500 psi load and shoot it. I'm saying I wouldn't reduce the powder charge of a 7500 psi load and recommend it to a new reloader without telling him of the possible problems that could be encountered.
