to answer all your questions at once here goes.

I have shot a few rifles, mainly the 30 30 I had in ky and AR15s, never shot a bolt rifle, put I am very comfortable with guns.
I can deal with recoil, I had no issue with the 30 30 or my muzzleloader with 150 grains of power.

I checked and dpms has a 4 round listed for 44 bucks with a 6 week wait remington also has a 5 round mag for the r 25

will mainly be hunting deer, if I remember from my trips down a few years back they have some hogs in part of the state as well
