Like others have said, H414 and Win760 are exact same powder. Only difference is container/label/lot#.
I've had outstanding results in the .30/06 and 180gr bullets with H4831.
You really can't get too much of it in the '06 case to go over pressure. However, you may get better accuracy at lower charge levels.
I'd start with 58.0gr and work up to whatever leaves about half the neck empty. (varies between make/lot# of brass). This will allow you to still seat the 180gr Nosler Partition without damaging or mis-shaping the bullet.
I did a work-up with a new-to-me '06 back in 2009 prior to a Wyoming elk hunt. I used IMR4350, H4831, IMR4831 and RL22.
Oddly enough, the lot# of H4831 I had gave me the best velocities of the 4. I ended up going with 55.0gr of IMR4350 because it gave the best accuracy (near 1/2moa) from my 6lb Colt Lt.Rifle. Velocity was 2,770fps. H4831 gave 2,840fps at 60.0gr from 24"bbl. This was with Federal #210match primers, and Federal brass. Winchester cases hold a little more powder with Norma brass being the highest volumn and best brass.......if you can afford it. I use range pick-ups.
I don't care for H414 due to fluxuation in lot#'s (lot of variation in accuracy/velocity). One lot I had got 2,800fps with 60.0gr under a 210gr Nosler Part's from my .338/06. Next lot# got 2,640fps with same brass, primers, and box of 50 bullets.......
