Just got my 6mmBr R5 from Competition Shooting Stuff (http://www.competitionshootingstuff.com/)...after about 2hrs of break-in I shot a .211 inch group at 100yrds...29.7gr Varget with 107 Sierra MK. Not being a "group shooter" I think I calculated it correctly, .454 inch total group minus .243 for diameter of the bullet equals .211. I tried 29.5, 29.7, and 30.0 grains of Varget...all groups could easily be covered by a quarter but the standout was the 29.7 grains. The components were Lapua brass, CCI 450's, 29.7 grains Varget, and 107gr SMK. What a shooter...I hope I can put it all together as a bolt gun across the court (I'm a 20+ year service rifle guy).

Find a single hole in the paper and mic that. Depending on what type of paper you use,the hole can be as small as .20".
Then measure edge to edge of your group minus that diameter.
