The data for this powder only goes up to 400 grains in 45 70. I have some 405 grains i want to load. Been slim pickens at the LGS and reloading supply place. I picked up the 530 because its good for 223 and 6.5 grendel.
Would the 400 grain loads be too light?
Site seems to be OK. Load issue should be resolved now.

Stets, I looked in 3 different manuals and came up empty with that powder[N530]. If you found/have a load with a 400gr cast, you should be fine.
I can't imagine 5 grains making a difference. Perhaps reduce the charge 2/10ths of a grain?

Just watch your brass but 5 grains in a bullet isnt going to make that much difference. Like Tom said back it down a half grain and give it a try.
Don't let the old man in
