A lot of shotgun only hunters want fast light bullets, with less recoil. And a little longer range. Still will have good ME.Sabot speeds below. I like 600gr Dixie and but test everything so guys know about them. Been testing the Encore with the Nef loads. Barrel breech is one inch same as muzzle, where the NEF is 1.200". It has dovetails cut out in bottom of the barrel for the nuts for the forearm screws. ... At the bottom of dove tail there is only .060" thickness. Before reaming had back one fill welded as it was where the taper for the forcing cone ended up with 3.5" chamber. I load it with 10 gr less powder than the NEF on all different slugs and weights. Like the BPI sabot in 3.5" plastic in NEF, 437 gr slug, 120gr 4227, 2400 fps, and in Encore 110gr 4227, 2270 fps. In 3.5" RMC brass case, same sabot/slug in NEF 140gr 4227, 2600+ fps,Encore 130gr 4227, 2500. The Encore is now 12 lbs, with hollow in butt and recesses in forearm with lead shot.In pic you see NEF And Encore with RMC brass cases started in chambers. Ed
