Hunting load for my 375 H&H Magnum is the 300gr Accubond using Re19. I followed the Nosler data for load development and get around 2375 fps MV from my 21-1/4" barrel Sako 85 Kodiak rifle -

The A-Frame is a lead cored bullet so you can use any 300 gn load data for it. I think you will probably find that RL 19 is a little slow for the H&H for optimum ballistics, RL 17 should be more appropriate burn rate as is IMR 4350. I use RL 15 in mine with 270 gn bullets as I couldn't get enough IMR 4350 or RL 17 in the case to get my desired velocity, with the 270.

I use 79.5 gr of H4350 and get 2636 fps with 300 gr Sierra Gamekings. 3.665 COAL, Lee crimp, Hornady cases, Federal 215M primers, 0.84 MOA. This amount of powder is .5 gr short of a compressed load. 5 shot string measured with a Magnetospeed V3, 2636 with a SD of 4.9. This is out of a Sako 85 with a 24" barrel.

300gr Woodleigh data. Re17 and H4350 appear to be good for maximum speed.

 

[RangerPark]

All those loads are fairly conservative. Hodgdon's website lists 81.5 grains max for H4350 with 2645 fps.

Swift a frame manual 1st edition:

r19 min 73.9 2350 max 79.5 2583 with 102% load density.

hope this help.

With the 300gr Accubonds in my Sako 85 Kodiak OAL is limited by magazine length.
