I'm having a 6x223 built with a Hart barrel on a Sako L 461 action. Primary interest is shooting 85gr bullets. I have load data info from Sierra and Hodgdon. Anyone with 6x223 or 6x47 shooting experience have recommendations on powder?

Used to was.... H4895 was the way to go.
With advent of newer powders over the past 30+ years;
you've got more ( better ) choices.
With 6mm bullets on this case cap, I'd go a tad slower on burn rate than H4895. Say.... VV135, or Varget.
What bullets do you have in mind ??
Best of luck in your endeavors.

Barnes TSX or Nosler Partitions. I'm going to use it as a close range (Adirondacks) Whitetail rifle. I love the Sako Vixens, but am not confident in the .222Mag. without snow to follow up on.

I've had a couple 6mm-223 T/C Contender Handguns over the years. I always relied on either H-322 or W-748 to shoot 60gr. to 80gr. Bullets. More recently I had a couple of 6mm T/CU T/C Contender Handguns. The one perferred H-335 while the other one perferred Hodgdon Benchmark with 80gr. Bullets.
I have not shot anything heavier than the 80gr. Speer Hot Core Spitzer in my 14" Handguns but it has done an excellent job on Whitetails here in northeastern South Dakota.

Have shot the 6mm-223 for a number of years and dropped some 25-30 deer with it.
Would have a hard look at the sierra 85gr gameking as it not too hard for 6-223 velocities. It has a little trouble dropping deer on the spot when shot in the lungs, but very good when going for breaking bones.
Have also tried Hornady 87gr vmax which was a good bullet for lungshots, but onl dropped a few deer with it.
VV N130 was the best powder in my rifle, about 840 msec in a 24" barrel.
