Have you ascertained what kind of choke your 18inch barrel is?
Most stock barrels are cylinder choke like that which means they will work fine for a defensive shotgun.
What you're gonna wanna do is pattern your gun. Take your defensive loads and shoot a large target at ranges from 5 yds to 20 or so. This gives you an idea of the spread you are working with. Modern ammo and guns are so good the pattern is usually .5 inch wide per yard of travel. This is a huge improvement over the 1 inch per yard of travel it was when i was a kid.
As to.barrels? I dunno man. In all my years i've never seen it quite like this. Local gun stores might have one. Also mossberg of all people makes a great 870 barrel. That is what is on mine.
Yeah, lead shot doesn't fuck up steel rifling but as far as i know it fucks your pattern up pretty good. Doughnut-ish is what i heard.
I'd just get a field barrel for shot. Unless it's Benelli where spare barrels cost wayyyy too much. And i love Benelli.
Need an 870 field barrel? Hmu.
