I bought this ammo from Brownells - REMINGTON SLUGGER MANAGED-RECOIL RIFLED SLUG SHOTGUN AMMO.I have been told this ammo which is a rifled slug will work when shooting through a smooth bore barrel. I am going shoot at paper targets for accuracy with this ammo using my 18 inch tactical smooth bore see picture below, I assume my tactical barrell (no Choke) shown below has a smooth bore? I just ordered a picanny rail for it and also picked up a Tasco red dot scope for 25.00 from Walmart. Please let me know if this is good set-up for fun target shooting, I think it is? This is my exact gun.
