Dan--I've got that barrel.
With the factory x-full choke shooting shooting 3"#5 Rem. at 15 paces, I can drop a golf ball thru the hole, at 40 paces it's not so impressive. Haven't tried different shells much to give an opinion.
I do know it doesn't like 2 3/4 #6 at any range.
Will kick like hell without some weight in the buttstock.
I am thinking about trying a different choke and loads to see how that may work.
All that being said, I have killed a number of birds with it out to about 30 yards.--woodsrunner
