Are you guys seeing any accuracy discrepancy between the different flash hiders people are ordering?
Mine with the standard A2 had a .8 test target with it. 39 |

My OBR shipped with the SF and a .68 test target.
Testing with some older M118LR the best 5 shot group was .35 with an avg around .5. Federal GMM 175 shot pretty bad for me with an avg around .8, BH 175 Match worked pretty well shooting an avg of .5 (20 rounds of each in case anyone cares) I happened to notice that Larue's OBR mags allow for a slightly longer COAL then the DPMS mags I have for a LR308, just long enough that I could fit some tuned loads from one of my bolt rifles...It kind of surprised me, but it was shooting in the .3-.4 range. I may have to further develop this load for the OBR. All shots were @100yd from a bench. !!!STANDARD DISCLAIMER ABOUT NEEDING TO WORK UP TO THIS!!! LC LR '01/'02 once fired brass 46.3gr of RL15 Fed 210M 155gr Lapua Scenar ~2.850 COAL (If someone wants ogive measurement let me know) Out of a factory 26" TRG-22 it runs @2950fps - I have not put the OBR behind a chronogaph yet... -pd |
