I shoot a 107 smk in my 22" uintah with Lever, the MV is <52ksi for my node at 2718. 2700-ish is a fairly wide node btw.
In Hornady's 108-110 data (your 107 might go 10-20 fps faster than the 108), max CFE is listed (gas gun) at 29.1, 2575, so <52 ksi.
Their table below this data extrapolates the 18" barrel in the data to 22", and 2695.
So 2 possible nodes for you in CFE, ~2625 MV and 2700 MV. Factory 108's in my 22" shoot 2650-2660, sd I forget but usually <1.0"/100 yds.
You could work up from, say, 27.5 grs to the 29.1 and see what kind of MV's and SD you get.
