Just bought a brand new Rem 870 SM, Shadowgrass Camo, 28" bbl and picked up a JH .665. Im hoping i did ok getting the .665 rather than the .660. Bass pro didnt have the .660. Anyone have any recommendation on loads out of this set up.?(Hevi or PB) The only thing i have done to this gun is deep clean the barrel and i couldnt believe the mess that came out of a brand new barrel..What numbers are people seeing out of this setup with Hevi 13 3.5/2.25/6's and Hevi 13 3.5/2.25/7's. Just curious what sort of numbers to expect before is start blasting away.
