[QUOTE="SQ Stalker, post: 305363, member: 18663"] For my .270 win, I picked a mid weight charge and varied seating depth by fairly coarse increments. With the best depth from there I continued to find the best charge my loading 2 rounds ea. @ +-5gr (over 6 grain spread from mid to the max of MY rifle). From there I loaded 5 shots ea. @ +-.3gr (over 2 grain spread centered around previous best charge). I then went back to seating depth and loaded 5 rounds ea. @ +-.005 (over .020" spread centered around previous best depth). I was using various brass w/ Fed 215M primers, H4831SC and 150gr Berger VLD bullets. This process seamed to work fairly well, I went from 1.5 MOA to just now getting below .75 MOA avg. Some groups at .5 MOA and a couple just below that. I've just started reloading this summer so it's all a learning process. I'd also 2nd the recommendation of the Hornady OAL gauge to measure bullets and seating depth from the ogive. The measurement from the tip is fairly worthless. Good Luck Stalker [/QUOTE]
