Varget Powder data for 45-70 reloads

I have a couple of pounds of Varget left over from my .223 loading days. I noted that it is much slower than IMR4198 and thought it might work in loading 45-70...couldn't find much on the subject so I called Hodgdon.
45-70 (gov't) for 300gr, JHP the start point is 57.0grs and max is 63.0grs which will slightly compress the powder.
For 400gr Lead Cast the start point is 40.0grs and the max is 50.0grs.
Lever guns need a roll crimp, single shot guns do not.
I'm thinking that the less air space in the cartridge might improve performance...

Tubular magazines or heavy recoil even in a box magazine require a a good crimp to hold bullets in place. As a side note - topping the magazine off after a few shots every time, puts a lot of stress on the ones that stay in the magazine.
Most all my loading stuff is old roll crimp - I don't think I have any taper crimp.
I like full cases or even lightly compressed loads in rifles. Much more consistent ignition as the powder charge is always in the relationship to the primer. I choose my powder that way. Using up odd lots, well you can't have everything.

Yes, choosing a rifle powder that fills up the case much more CONSISTENT accuracy usually.
I've seen some of the powders that leave a lot of space in the shell that would group different and erratic if the barrel was pointed up before shooting vs pointed down before shooting. (powder against primer vs powder away from primer) I call these type powders for rifles firecracker powders.
I always load rifle ammo using balance beam scale and a powder trickle...hard to screw up that way...every load is dead on.
