[QUOTE="Wachsmann, post: 1088281, member: 10429"] I finally got out today to do some shooting. My first load is my single feed load that gave me .5moa at 200. Its 89.3 grains of retumbo, 230 berger, seated to OAL of 3.790 and base to ogive is 3.0945. Measured velocity is average of 2930fps. Next load today was the 210 LRAB with OAL at 3.650, and base to ogive 2.966. Sad thing is I forgot what powder charge I used but I got average speed of 2960. I'm sure it was retumbo just don't know how much. I'm thinking something like 90.5 grains....Next load I pushed those big 230 down to mag length at 3.65 OAL and base to ogive was 2.952. powder was 88 grains of retumbo right from the berger reloading book. Average velocity was 2773. Now here was the kicker. At this seating depth they shoot 3/4 inch group at 160 yards. Not great but not to bad. so I might try and develop this load out to something better. I would also want to try and get it up to at least 2900fps. I think it would of been better because I think I pulled one. I had 3 that stacked right on top of it's self. Some what funny since now I have a small divot in my ar500 steal.
