Been using rl25 for all my loading in 300 rum and 7mm rum I am loading 150 to 160 class bullets in 7mm rum and 180 to 200 in my 300 rum I can't get any reloader powder can't find any so that's about out of ? . In the 7mm rum currently running from 3450 t0 3557 fps in chronograph with a 26 factory barrel the 300 rum is a 28 inch barrel and I'm getting 3400 with 180 sst through chronograph and not a max load .I currently have imr 7828 h1000 us869 h4831sc imr 4831 h4350 a 4350 looking to keep velocity close any help appreciated thanks in advance
