happyhunter Posted August 21, 2016 Report Share Posted August 21, 2016 Loaded 10 rounds with, (only had 10 cases prepped) Lapua brass (fl resized, trimmed to 1.555", chamfered deburred) CCI BR-4 primer 30gr H4895 Bullet seated 20thou from the lands. 10 shot group measured .76" with vertical stringing in more of a "C" shape. Will increase powder charges to 30.3, 30.6, 30.9 once I've prepped more brass this afternoon. Just wondering of anyone else runs this bullet/combo through their br's? Powder to hand is varget and h4895. Link to comment Share on other sites More sharing options...

Swarovski1 Posted August 21, 2016 Report Share Posted August 21, 2016 I think I will be abandoning my 338lm project for the 6mm br.ive many more uses for the 6mm br as the 338 is restricted to range use. Link to comment Share on other sites More sharing options...
