[QUOTE="AI338LM, post: 1064426, member: 89485"] Berger web site has interesting info on seating depth. For hunting load 6 rounds each 0.010, 0.050, 0.090, and 0.130 off lands and shoot in 3 shot groups. In my 300 win mag, I found the best group at 0.090 off lands for the 230 OTM bullet. I got basically a two hole group ovelapping from the three shots. Was shooting RWS brass, WLRM primers and 68 grains of N165. MV around 2550 from 24 inch barrel. I will now do powder charge ladder at that 0.090 jump distance to see if I can get good group at higher velocity. [/QUOTE]
