I use an 835 with 24" rifled barrel with cantilever scope mount for deer hunting. My son uses a 20ga 500 with the rifled cantilever scope mount barrel.
We have killed a s--t ton of deer with our shotguns.
Mine is accurate enough, producing 3" groups at 100yds with Lightfield slugs. My son's is really accurate, like three touching at 100ds, with Federal all copper slugs.
$250 seems steep, but is been awhile since I bought a Mossburg.
