[QUOTE="JeffVN, post: 1114495, member: 2261"] I thought I would add a bit more information to my prior posts about the solids, since I had a chance to shoot and gather some data regarding the 30 cal. 155 gr. pills and the 255 gr. .338 pills over the weekend. All velocities were obtained using an Ohler 35P chronograph w/ proof channel (so its actually an average of 10 inputs from 5 shots) set up 13' from the muzzle of the rifle. 30 Cal. 155s shot from my 27" 1:10 twist Kreiger .308 (Chambered and built by Terry Cross @ KMW). avg. velocity was 3014 fps (5 shot average (including cold bore); ES of 15, SD of 6). .338 - 255s from my 30" 1:10 twist Bartlein .338 LM Improved (Chambered and built by Warner Tool). avg. velocity was 3,120 fps (5 shot average (including cold bore); ES of 14, SD is 5 - using 101+ gr. H1000). .338 300 gr. Lapua Scenars from 30" 1:10 twist Bartlein .338 LM Improved (Chambered and built by Warner Tool). Avg. velocity was 3,025 fps (5 shot average (shot immediately after the solids - without cleaning - so no cold bore velocity here); ES of 15, SD is 6 - using 103+ gr. RL-33). JeffVN [/QUOTE]
