.236 vs. .237 for an 8 twist 6BR. Anyone? Thanks.
Next, looking at another Bartlein for a 6mmBR project, an 8" twist, bullets used up thru 107s.
My last was a 4 groove .237 shot very well.
Thoughts on 237 vs 236 (speed and accuracy), and 4 groove vs. 5R - (accuracy and barrel life)? Edited, read a prior ? and post by others on grooves so I think I will stick to a 4 unless I hear a compelling story.
Thanks for all replies.
