[QUOTE="Bishop, post: 935230, member: 26163"] The 3 shot group on paper measured .396 ish outside diameter. Comes out to .088 CtC. I'll call it 1/10th I reckon. The 5-shot group on the steel is at 600 yd, didnt measure it but that steel plate is supposed to be 10 inches diameter. Wind bit me on the one to the left, looks like I am seeing a bit more vertical than I want. It is most likely due to my shooting form and aiming point though. I was just trying to center my aim in the plate, nothing really small to focus on, gonna have to get some dots on those plates! This load was 43g IMR-4064 175 SMK length sorted by ogive comparator *but not weight sorted* once fired lapua brass, F/L sized with a .336 bushing die, .005 jump, out of my Longrangerifles llc .308 win. avg velocity 2773 the S/D was 9 for the 5 shots I chrono'd with the magnetospeed before I took it off to shoot the group, the ES was like 20 or less I cant remember for sure. The magnetospeed does affect accuracy when it is hanging off of my barrel. However it still wants to shoot mostly 1/2 in groups with it. The load chrono's at 2773 avg fps. Winds were gusting from 0 to 10mph today, made it interesting to shoot. The wind makes a HUGE jump in how it affects the .308 bullet from 4/500 to 600 yards it seems. When the winds are pretty constant, its easy, but when the wind dies from 10 mph to 1.5 mph, and then gusts back up to 10 mph, or vice versa, as you start pulling the trigger, it makes it quite interesting! Reasonably happy with the load, wish I could try some different primers though. I have enough IMR-4064 to load roughly 3k rounds though, so I will be shooting this stuff for a while i think. I'm pondering doing a very light neck turn on the brass to uniform the neck tension as much as I can just to see if I can squeeze some lower S-D out of it. The annealing machine is going to have to wait till next year though sadly. [/QUOTE]
