Myself I've tried the book load with H110 max is 44gr with 300FTX I went max as it is very loose in the case.
Ignition with LPM and I tried LRM ignition was pore in very cold weather about 10 out some no fires. Inconsistent. fail to fully cycle the gun.
I found online somewhere someone was using 36gr of N110 with 350xtp
So I tried 36.5 with the ftx and had good results clean burn full function and 1.5" groups at 100 and single hole groups at 50. Note I load to just under the crimp groove for a light taper crimp. This is a pretty light load could go up but it works well.
