Normal practices: Start at 72.0 gr, work up to 80.0 grains for SAAMI standard loads with 400-grainer.
AA-2460 will also do about same at same charges.
H322 at slightly lower charges.
H4895 at higher charge weights with compression.

All those powders are temperature insensitive and good choices for 400-grainers,
AA-2230 is top pick for me.




Thank you ! I had just picked up 8lbs of the 2230. I was hoping that it would be suitable.

Edit:
Should be no problem with that COAL in my 458 Winchester.

Guessing the 2230 will work on the 458 Lott also. I have to show it some compassion also.
