Well, I've had some mixed results with the 6BR, but, not better than 1.5MOA.

Varget was a bit erratic, but, I think I need to revisit it since it gave a bit lower vel with same volume charge as the IMR 4198 (which I have used successfully in the .308 with mid-velocity cast).

My first loads with 4198 were around 2200fps. This is on the high end of spin rate for this caliber. The 1-8 twist is the problem. I tried some lower loads and have a candidate at 16.7gn and 2120fps but relatively poor es/sd. 1.5-2MOA seems average for this load. Not great and still some bad fliers (typical of too high spin rate). When I went to lower loads the muzzle vel was very erratic. This is 100yd, squares are 1/2".

So, am going to try Varget a little more and see what happens. I'd like to be in the 1800fps range.

A new guy at the range was shooting his Schuetzen rifle (breech seating). Sharps Borchardt action, .32-40. He was getting 0.3" and 0.4" groups at 100yd.
