Sir Roo,
Sir John gives good advice.
Sure you can use H4198 with 400-grainers, but you will get higher pressure (not lower) with less powder, and might blow a gasket trying to get same velocity as with AA-2230.
If you want about 100 fps slower, with less powder, less recoil, and excellent results otherwise, use the H4198.

Reviewing my 480-gr DGX-Bonded loads with AA-2230 and AA-2460,
I found something I never explained.
78.3 grains of AA-2230 gave about same results as 77.0 grains of AA-2460.
Same rifle, and all other specifics same except negligible temperature difference.
Seems to indicate AA-2460 is not a tad slower than AA-2230.
Stay tuned:
