[QUOTE="rpierce, post: 2137075, member: 20643"] Haven't had time to post it but I spun up a 338 Norma Improved for myself. I did it in a heavy setup as I plan on taking it to a couple matches next year. The load I settled on for this rifle is a pretty mild one with this 32" barrel. 88 gr of h1000 is pushing a 300 gr berger at a mild 2850. Didn't see pressure until 3000 fps. With N570 I didn't see pressure until 3100 fps. However this load of h1000 has a SD of 6.5 fps for 61 shots on the labradar. Its also only getting like .003 throat erosion every 100 rounds. Barrel will last a very long time with this load. Info on groups in post. First 3 shots down the rifle measured .247"@100 yds. Random Starting load. 3 shot 100 yd group measured .153"@100 with h1000 load 580 yd group measured 1.145"/.188 moa at 580 yds. Had .502"/.082moa vertical. 1000 yd group measured 3.708" with 2.502" vertical. Second 1000 yd group on steel measured 4.988". Rifle has the following components: Surgeon 1581 XLR Evolution HD chassis with a sick paint job by Grant Gillespie at Viking Armament Cadex Defense Bipod Brux 32" 9.3 tw with 1.350 shank Aaron Hipp tuner Self timing 5 port "Muscle" brake with 3/4x24 threads Triggertech Diamond Trigger set at 8 oz and timed to action Tangent Theta 5-25 GEN3XR scope bedded into a set of NF rings Long Range Arms level [ATTACH type="full" alt="127898358_984998561986698_4513835246070201628_n.jpg"]257369[/ATTACH][ATTACH type="full" alt="134376048_391955621873791_5140449640326257635_n.jpg"]257370[/ATTACH][ATTACH type="full" alt="135304964_1037890463379229_7453523483739744660_n.jpg"]257371[/ATTACH][ATTACH type="full" alt="136476790_756505665287392_9193584549285499565_n.jpg"]257372[/ATTACH][ATTACH type="full" alt="122440577_724621818266798_960918239878168906_n.jpg"]257373[/ATTACH][ATTACH type="full" alt="100 yd group.jpg"]257374[/ATTACH][ATTACH type="full" alt="132799878_4152018598146085_638403665682806087_n.jpg"]257375[/ATTACH][ATTACH type="full" alt="128361673_812635862852579_7295439979448045566_n.jpg"]257376[/ATTACH][ATTACH type="full" alt="128253766_1722903301219601_5662309353888583655_n.jpg"]257377[/ATTACH][ATTACH type="full" alt="132321984_1486957548160094_7735926076017745601_n.jpg"]257378[/ATTACH] [/QUOTE]
