I know this is off the subject but just for some food for thought. I have the same rifle as you are writing about and I have been usingIMR 3o31 with hornady 350 Rn with 56.5 grains with win cases WLR primer ,this is after I called Hodgdon. They told me their loads are tailord to the strength of the firearm ,that worked for me.My first loads at the starting load give me consistant 1865 fps with moderate recoil and pretty damn good accuracy. I may experiment a little but these loads seem to work well, I hope to get a chance in Vt this next week to try one on a deer or bear. I may try some hard cast bullets later as the hornady prices are getting a little rich for this old retired reloader ,I still have powder that was marked $2.25 LB that 's from almost 40 yr ag, been at the bench for 50 years where does time go..good luck ..
