.40cal Smokeless Load Data Help

[schamsy33]

Looking for some help getting started with a .40cal smokeless build I bought from another forum member.
It is a 25" Shilen 1:16 twist on a Rem 700 SA with the arrowhead Gen2 LRMP system.
I will be shooting the arrowhead 275 grain XLD bullets.

I have H4895, H4350, Varget, and IMR 4166 Enduron available. I have seen some ranges of 68-75 roughly for the 4166 and H4895, but was hoping to get some clearer suggestions from anyone shooting a similar setup.

Thanks

Your best bet, is to go to one of the several muzzle loader forums, and look up their load data there.
