[QUOTE="codyadams, post: 1436779, member: 87243"] Ok guys....FINALLY was able to get some time this morning to go shoot my load work-up. I have to say, I am excited with the results. So here is what I found .308 Win 24" Savage 1:10 twist barrel Hornady .308 brass Berger 215 Hybrid seated at 2.965" (.080 OFF LANDS) CCI BR-2 Primer Reloder 17 42- 2365 fps 43- 2399 fps 44- 2453 fps 45- 2491 fps 46- 2532 fps 47- 2579 fps // faint ejector mark outline, easy bolt lift, 48- 2625 fps // light shiny ejector mark, slightly noticeable bolt lift increase, slightly cratered primer 49- Did not shoot, pressure was obvious Also, all 7 shots printed within a 1.25" group, less than .75" vertical, the spread was horizontal, and likely due to pulling a shot to the right. I will post pictures of the group and cases in my next post. I am very happy with this, I believe I will find a good load in the 45-46.5 grain area, and it should be running 2500-2550 with these 215 Bergers. Just for comparisons sake, I will compare the 1000 yard ballistics to a few other bullets with predicted velocities. Using my current atmospherics (22.8 for pressure, 55 Degrees f) and a 5 mph crosswind not accounting for spin drift or coriolis, results are as follows- 1000 yd performance: 215 Berger @ 2510 fps retained velocity: 1663 fps retained energy: 1320 ft. lbs wind drift: 2.3 MOA elevation: 30.2 MOA 180 Berger EH @ 2725 fps retained velocity: 1662 fps retained energy: 1104 ft. lbs wind drift: 2.6 MOA elevation: 27.1 MOA 178 Hornady ELD-M @ 2725 retained velocity: 1599 fps retained energy: 1011 ft. lbs wind drift: 2.8 MOA elevation: 27.9 MOA And just for fun, I'll compare this to a high end 6.5 creedmoor load.... 140 Berger EH @ 2900 fps retained velocity: 1845 fps retained energy: 1058 ft. lbs wind drift: 2.2 MOA elevation: 23.1 MOA Really quite impressive for a .308....only .1 MOA wind drift behind a high end hand loaded 6.5 creed, and over 250 ft. lbs more retained energy. I don't usually take too much consideration for elevation, as that is an exactly quantifiable number that we use an electronic rangefinder to account for, and that only leaves the velocity for the .308 to fall behind, which according to Berger, 1600 fps is still enough for their bullets to properly expand, but even at that, the .308 is only 182 fps behind the creed. And also, this is at 1000 yards, about the max hunting distance for these rifles. One other thing, in this 14 lb rifle, recoil was very manageable, even from prone position, without a muzzle brake.
