Load info for 345gr 45-70 ?

[xring1]

A friend cast up some 345gr HP's for me. I need load data for them.
I have a bunch of IMR3031 I would like to use up.
All the load data I can find for bullets that are close in weight is either for jacketed bullets or the data jumps from 300gr to 405 gr.
I do have Goex FF but would like to try the IMR .
The rifle is a H&R SB2 and from what I have read will handle some pretty stout loads but I am looking for accurate loads for hunting deer.
Any suggestions ??

With that powder start out with 38 gr. of IMR-3031 and work up to 48 gr. IMR-3031. The starting load of 38 gr. is safe in trapdoor rifles and the 48 gr. is listed for rifles in the Win. 1886 and Marlin 1895 rifles. 38 gr. about 1200fps and the 48 gr. is 1600 fps. for 350 gr, boolits.

IMR-3031 is a Hogdon powder and Hogdon has a free web site that gives reloading data on all their powders by caliber.

Funny all my 3031 says DuPont or IMR.

Hogdon bought out IMR a few years ago and now are all considered Hogdon by some. Same as Western buying out Accurate Arms powders, haven't been able to find AA powders since then.

Thanks for the info
As I said I know the H&R SB2 Handi rifle will handle some stout loads but I will be hunting deer not water buffalo.
i looked at the Hodgedon data and thought It would be in that range but wanted to be sure. I am new to BP loading. I guess I will have to put some filler in the case.
Any recommendations on filler and wads. I am using alox on the ones I resized last night

As far as rifle strength, one of the shooters that had one of the old early version of a Handi said that the shooter would quit before the rifle!

That's God's honest truth!:lol: My H&R buffalo classic handles the top 45/70 levergun loads, but is painful. That curved steel butt plate likes to take chunks out of a shoulder.

I wear a past magnum pad when shooting it, that takes the hurt out of it.

I shot quite a few of the Lee 350's, from trapdoor pressures up to the top levergun loads. Even top loads were comfortable with the 350's.. BUT you won't need top loads for deer, unless you want to flatten the trajectory for longER shots.

I never tried holy black or any substitutes in my Buff classic. Don't want to risk rusting it up. Kinda curious though, might still do it.

snuffy, go ahead and try some black powder. Just be sure and clean the gun when you get home from shooting it, not a month from then! Black powder isn't nearly as corrosive as it used to be. No, the powder hasn't changed, but the primers sure have. after cleaning it good with hot water, just be sure and give it a good coating of oil, or other rust preventative when you're done. I just bought my first 45-70 single shot rifle, an original rolling block, so I'll only be using black in it, and even if I could shoot smokeless in it, I would probably still shoot black in it, as that's what the cartridge was originally designed for. :)
