45-70 modern lever Lead data

[mobullets22]

Hi all. New account here. I have searched to no avail and hoping someone can point me in right direction. I have a new production Henry 45-70 that can handle the marlin loads. I have 300 grain acme powder coated lead flat point and H4198 powder. The only load data I can find for lead bullets are for trapdoor loads. Those loads are 30-35 grains, compared to the modern lever jacketed data of 50-60. Is there any conversion I can do for jacketed to lead data or specified lead data I am not finding? Thank you in advance.

Didn't realize Lyman 50th had modern lead data. I just ordered the Lyman cast 4th. Sounds like I'm safe to start around 30 range and ladder up to find a sweet spot.

H4198 is a good powder to start with.

what size are your bullets?

This is definitely what I'm looking form it doesn't have the H4198, instead it has IMR 4198. I know they aren't interchangable grain for grain but should give me a safe spot to start. Book is ordered. I appreciate the photo.
