If you cant tell by now i am pretty excited about my 6mm dasher build that is in progress. I am trying to learn as much as i can about this chambering. How many rounds will i probably get out of my 8.5 twist 6mm dasher barrel? Also i have heard that the 6mm dasher isnt very accurate at 100 and 200 yards. What is the general thought on this subject? My chamber will be cut with a kiff standard reamer for 105gr Berger bullets. No turn and i think the lead is 104?? Will i get very good groups at 1-200 yards?? Thanks guys :Lee
