[QUOTE="jamiebolseth, post: 1554609, member: 88495"] For the guys interested in RL26 data I did a test with the same 7 SAUM last Spring testing my cold bore plus 2 shots at 950 yds each day for 6 days. I wasnt really testing temp stability as much as cold bore shift. It was 19 shots total (shot 4 shots one day because I misjudged the wind and missed the target on the cold bore). I recorded velocity and placement on the target for every shot. Temps ranged from 36 degrees to 75 degrees. Long story short... There was a noticable (though small - around 10 fps) drop in velocity from the cold bore shot. But at the end of all 19 of those shots the SD was 11 fps spanning 6 days and about 40 degrees in temp. So that convinced me that RL26 was fairly stable in mid temps (30 to 75). This weekend's test suggests it's a little more sensitive below freezing temps, but still pretty good. At least in my 7 Saum.
