I will rewrite my org question: anybody useing SW Precision in a 6BR?

My notes show 28.5 SW Precision with a Hornady 105 BTHP to be an accurate load. I shot it 2 years ago and don't have a target to reference.

Thanks , I was figuring to start at 28.0 and work up .

Not yet but I plan to. I also will try CCI 450's. A friend is getting great accuracy with these in his Dasher.

I have one 6BR barrel that likes the 105 Hybrid, RP 7 1/2 primer and 29.8 SW Precision in Peterson brass.
I've been just over 30 grains without any problem but my particular rifle was liking just below 30.

Midway has a sale on swp powder. Just ordered 6 pounds. I'll get some loaded and shot in a week or so. I'll be using lapua brass and either br4 or 450s.

I was shooting 95 gr BIB FB bullets with SW Precision Rifle, in a 6BR. I got the best ES (11 FPS) at 29.0 to 29.3 gr using cci 450 primers. Velocity was averaging 2670 FPS, quite slow. I was getting about half MOA at 100 yards....not great. I went up to 30 grs. and got 2730 FPS, but my groups opened up, so I abandoned it. I switched to N140 and got better accuracy, 3/8 to 1/4 moa at 100 yards. I was able to get 2943 fps average velocity at 31.2 Gr N140, BR4 or cci 450 primers. ES was high though, 29 FPS, but I was ok with that. I always used Lapua cases turned to .009 for a .266 chamber.
The rifle is a 6BR, 26" Bartlein, Defiance Rebel action. I'm not shooting this rifle now. The barrel has just south of 4000 rounds on it and accuracy has slipped a good bit. A new Bartlein is due in June. I don't want to waste components.
I want to revisit SW Precision Rifle with the new barrel. I still have the best part of an 8 lb. jug of it. I also have 100 psc of Peterson and 100 pcs of Alpha 6BR brass ready to go.
