[QUOTE="muleyman, post: 205785, member: 11540"] I'm not sure what to look for in velocity. When I was making up loads for my 338 win, I looked in several older printed manuals as well as some newer ones. The old books show 75 grains of IMR 4350 with a 200 grain bullet. The newer show anywhere from 71.5 to 73. I loaded up 73 and 74 grains with a 185 grain Barnes TSX. When shooting the 74 grainers I had several shots in and around the 3050-3100 mark. Then out of the blue one at 3260. No signs at all of pressures and the S.D. were very sporatic. On the 73 grains the S.D were a lot closer however just the opposite happened. Had all at or around 3120-3150 but then had one at 3000 something. Is this a sign of being overloaded, according to the Barnes manual, I'm right there on velocity. Also they printed fairly well, a completley factory gun shooting at around 3/4"-1" at 100 yards. [/QUOTE]
