Cant really coment on the Browning or the Win but I can tell ya about the 750... Mine shoots great!!! I've shot reloads and factoey ammo threw mine with out a jam... I've prob put about 100 rounds threw mine... As for groups... It shoots between 1"- 1.5" groups... It shoot these groups with what ever I shoot threw it... 165gr-220gr... RN,BT,NP doesent matter... It groups the same
I'm happy with mine... I've killed 3 deer with mine... All 3 deer were over 150 yards, one being just under 200 yards... Definetly a bigwoods deer rifle
Now if your talking about bolt actions I like Browning... I'm a lefty
