I don’t have any experience with the Browning but I do own a Mossberg 695 12-gauge bolt slug gun and that thing kicks like a mule on meth. It is as accurate as any slug gun I have ever used (with the right ammo – like most guns) but it is a solid shooter out to at least 150. That being said, I also own a pair of Mossberg 500’s in both 12g and 20g with the fully rifled barrels and those are solid shooters as well. These might be cheaper guns and I hate that Mossberg pump rattle but these can shoot well past 100 yards with the right ammo and a decent scope on them.
The 695 likes the Remington solid coppers and the 500 pumps like the Hornady SST ammo. My 695 did not pattern well with the Hornady rounds.
