300 RUM with Berger bullets and Retumbo

get some 210vld. i use them with 90gr retumbo. one hole group @ 100yds! hit or very close on bowling pins at 910 yds. got my elk this year at 953 yds. dead in tracks! i have 28 in bbl and it gets 3150 fps. with muzzle brake grandson shoots it all day and he is 9 years old.
 
I was shooting 190 Sierra MK's in my RUM and I ended up with 94.0 grains of Retumbo all lit off by a fed 215 Mag primer. Load was very accurate @ 600 yards and safe in MY rifle. Start around 90 grains and go up in .5 increments shooting 3 shot groups and look for accuracy.
