I love my model 70 in 7mm rem mag and enjoy reloading for it.
I didn't like the recoil after about 30 to 35 rounds, so i had a limb saver installed.
If it was a 300 win mag or larger it would have to have a muzzle break as well.
I have never seen a Winchester that shoots poorly, I have seen people who shoot poorly and or have equipment set up wrong. Enjoy whatever you get.
