WebSep 5, 2012 · Over the last couple of days I have tried the 171gn Barnes with AR2213sc. Loads used varied from 55gn to 59gn. CCI BR-2 primer, Lapua 6.5-284 cases. Found plenty of accuracy and a node between 55gn and 57gn. Seared 0.015" into the lands. Didn't seem to matter what powder charge I used as they were all quite accurate. WebI figured it wouldn’t be fair to throw in the same amount of powder for grouping because one might do substantially better then the other. When I do load development, I find a velocity node with a significant low SD and ES-might not group great at 100 but will perform fantastic at farther ranges- then start to mess with seating depth.
