Ok, I just bought a box of 165 grain Speer Grand Slams to try in my .30-06. I have the Speer #12 Manual and it states a starting load of 54 grains, and a max load of 58 grains. I know they have a new one out, and it seems that EVERY manufacturer that comes out with an updated manual changes the charges. Could someone double check this for me with a #13 manual. I am sure that 55 or 56 grains of IMR 4350 should be safe, as I am shooting a Sierra Gameking (165) right now with 55 grains of 4350. I have tried a Corelokt (my grandpa's handloads) and the Gameking thus far, and just want to try something new. Give me something to compare. I have also tried other powders, and 4350 seems to be the best for my gun.
