as to bedding, every rifle is different.
Easiest way to start off would be to bed the critter like a Number 4: solid around the action, solid to the front of the chamber, float the barrel and have a pressurepoint just at the front of the forestock. Some of them like this.
My friend beds the critters absolutely solid, full-length, on Day 1, fires about 3 rounds between 18 and 24 hours later, then lets them stand for 3 days then takes them out and shoots them. He gets regular 4-to-5-inch called 3-round groups at 350 like this, but then, he IS handloading for the rifle. You likely won't get this with factory ammo.
If it were my own rifle, I would bed it like I bedded the one I am shooting: just like a Number 4, and then handload. I'm using Hornady .312 bullets, 150 grains, and my own Ishevsk 1939 is shooting regular 2 inches at 100 and I'm perfectly happy with that as, even with the new quadrifocals, I can't see any better than that!
Biggest problem in bedding the MN rifle is that very light and whippy fore-end, which is why my friend beds 'em solid all the way.
