The load reveals some great technique (reproducible). And it is plenty accurate. You can increase the charge, but there is no guarantee that you'll get any better accuracy. And there is more than enough velocity to take most any game in AB. I do love tight SD on a load.
Up to you, I'd want to try it only for curiosity, but as others have stated that is more than stout enough on both accuracy and speed already. Based on those 1" squares the group looks easy under an inch.
57 gr's of IMR 4350 with 165's is the old stand by load and also happens to be the sweet spot for my 06 with that weight bullet. But that doesn't mean yours will be of course. IMR 4350 produces the kind of accuracy with 165 and 180 weights that you can almost pick a charge weight out of the book ahead of time and be happy right out the gate. It's a bread and butter combo as you've proved once again.
Boomer,
That group will harvest any deer at 100 yards. Your group is good. In my experience, shooter error greatly contributes to inaccuracy. I run the same powder charge in my 1903 a3 and my gun loves it. According to the Nosler data, your charge is the middle of the road. If it is not broke why would you fix it?

Any 165 in the neighborhood of 2800 is "Classic". Enjoy your load and post pics of your deer this season, you will slay them! ( I once shot an axis buck at 230 steps with a little 308 Mod 70 Fwt and the 165BT. It might have been going 2600 at the muzzle, but it made a golf ball sized hole all the way through Mr Chital! That Axis was the size of a good mule deer. IOW, that 165NBT is just an awesome bullet! Have a ball pard!
My go to powder with the 165s has been IMR 4064 (mostly for nostalgia as that is what my Dad used to load up for me) but I see your result and I think I’ll try out your load. As witnessed by some pretty atrocious results I’ve posted on this forum, this old fart feels that a hunting rifle that will group an inch is plenty good to take afield.
Using the 165 BT right around 2700 resulted in dead deer for me.
If I were to change anything on your load, it would only be out of curiosity as I don’t see much to gain by moving that bullet any faster.
Fifty-six gr. of W760 and the Nosler 165 gr. AccuBond does 2880 FPS in my 24" 30-06 Mauser. Nice tight groups and the one elk I shot with it ram maybe 30-40 feet and died. Granted, one elk doesn't prove much but it worked. Bullet did not exit but we didn't find it.
