Will the same boolit at the same velocity but a different powder have different POI?
I'm going to answer my own question in a couple days, but I have two loads that yield a similar velocity.
The cartridge is 45-70 and the boolit is a NOE 460-350 RF and I cast them with a cup point. They are gas check'd and PC'd. And they end up weighing in right at 335-337 grain.
The two loads are varget and H335 and they end up sending that boolit right around 1900 fps in my Marlin 1895 with the 20" barrel. That rifle also has a Montana #101 sight on it...
The H335 load recoil impulse is a little snappier while the varget load impulse is a little smoother.
I've done some long range DOPE with the H335 load where I've been able to record the MOA measurements out to 625 yards. I'm kind of curious if the speed of the powder burn at the same boolit velocity will affect the POI at all...
Here are the contenders:
