So I just picked up a 300. Win mag remington xcr tactical thrown into a hs precision stock then aluminum bedded, with a tactical bolt knob and muzzle brake. Just mounted my NXS 5.5-22x50 and I'm not trying to make up a load. I picked up some 210 berger VLD's, h1000 powder, remington brass, remington 9 1/2 mag and federal 215 primers and trying to figure out where to start. I'm hoping to get it set up for moose this year! Going get we dialled in and out on the range asap! Little help would be appreciated. I wouldn't mind powder charge, and overall length!
