GREAT rifle even BETTER round!!!
One of my ALL TIME favorites!! You got a real score at at price you paid!!!
I am lucky enough to have both models, the M 375 and the M 375S. One has a safety and one does not. here is the 375S:


I put a Scout scope set up along with a set of HD peeps W/an Iridium front blade, as backup.
My all time favorite hand load scoots a 225gr bullet at close to 2200 Fps. Shot a number of deer with this load, works great. Accuracy was better with reg scope, but fine for hat I use it for. At or just under 2" at 100. With the std scope mount and the 225GR load, I was easily under 1.25@ 100 yards. The 2X fixed scope just doesn't let you see as good. But like I said, under 2" is all I require form this gun.
Good luck with yours!!!
