I use a Rem 870 with cantilever rifled barrel and a relatively cheap scope (can't remember what it is; came with the gun). I can do a 2" group at 100 yrd. with Hornady SST shotgun rounds without really trying very hard. I've never pushed it past 100 yds. as that is getting beyond the range I need to shoot but I think it could do it.

I didn't think "150 yd. tack driver" and "shotguns" could or should be used in the same sentence? I was under the impression that2" groups at 100 yds. is pretty darn good for slug gun, or am I mistaken?
