I got out to the range this morning, but conditions were quite poor, with blustery north winds. Tried to set my chrony up but it kept blowing over. I was testing to see if there was a difference in accuracy between the COAL's of 2.180 and 2.20, using the Nosler 95 grain BT's and the Hornady SST's. I shot 5 of each bullet type at each COAL, and from the results I have concluded that for this load in this rifle there is no difference. The BT's grouped at 1 1/2 inches and 1 1/4 inches; the SST's both grouped at 3/4 inch. I have rifles that are extremely sensitive to COAL, but this one does not appear to be. I've tried changing the seating depth with Berger Elite Hunters and the Hornady ELS Match bullets, but have seen no statistically significant difference in accuracy.
