All my experimenting stopped when I tried N135. 6mmBR with a 13.5 twist barrel. No other powder came close except N133.
I agree with you. My best 6br load is,30.1 LT32 at 3400 with the 64.2 Berger column bullet. I have used 2 different lots of the Berger column bullets. They both shoot the same.I have a zero fb 6BR 13.5 twist at 24",,with the 68 Berger,,68 Barts BT and the Berger Column bullet it shoots really well with VVN 135,,8208,and Varget ,,but I think the LT32 would agg the best in long strings,,and regardless of the powder or which of those 3 bullets it shoots best between 3350 and 3400 fps,,
my best agging load in this bbl is the 64.2 gr Berger Column bullet and LT32 loaded to 3375 fps,,if 300 yards was in the course of fire I would shoot Barts BTs and VVN135,,might even shoot the Column bullets at 100 and 200 and switch to the 68 BTs at 300,,
Here's a set of 5 shot groups I shot yesterday at 100 with 68 grain hillbilly FB bullets LT32 at 29.1 grains and a BR4 primer from my new 6 BR
