[QUOTE="jweigel, post: 1204706, member: 72021"] I have since shot twice using N570 and the 180 VLDs. Yesterday was 70 degrees out and I did get ejector marks at 72 grains on up. Hard bolt lift at 72.5. But the 71, 71.5 and 72 all had MOE under .5. 71.5 was .433. average speed was: 70.0 - 2970 71.0 - 3017 72.0 - 3025 I was also shooting my 7STW with the same bullets and powder. My go to Retumbo load with this bullet was 78 gr running 3080 as corrected with Strelok out to 1000 yards. I shot a 3 round group to see how relative the speed was this day and it was 3044. Three shot group average 3044 shot a few weeks back (50 degrees out). WOW.....that is crazy speed out of 7RM. I would love to use 72 grains as it has really low ES and great MOA but getting ejector marks (70 degrees out) I will drop back to 70 to give me a little room. So as not have have a 7RM shooting as fast as my 7STW with 180 VLD....I was able to get good MOA and a very tight ES with 80 grains running 3114. Will stay with this for now. jjw ND [/QUOTE]
