New Sherman Wildcat based on a .308 sized bolt face

Really wanting to do this as I have a 7mm saw and see this makes me want a new prs barrel. My 7 saw is a hunting rifle.

Does anyone have a starting load for the 7SWC? I'm having a he'll of a a time finding it. I am assuming that, when seated properly, even the 190's will load out of a standard short action magazine?

These chrono numbers should be disregarded. Ran 38 more rounds from 39.3 to 40.2g. Range of fps was nearly flat in the mid 2500s across the charges except for a 2994fps. I thought 2550 from 38.5 of n150 in 26" seemed a bit fast. Chrono obviously having issues.

What Chrono?

This was my magneto sporter which I haven't used for sometime. Action is in Foundation, so couldn't use v3 w mkm mount that I typically use. ( due to angle of forend).
I'll move action to chassis and start over at 39.9.
