I have a Remington 870 Express12 ga.that has a 23 inchfully rifled barrel withcantilever scope mount set up. When shooting Winchester's 2 3/4"Partition Gold SabotSlugs orRemington's 2 3/4"Premier Core-Lokt Ultra Bonded Sabot Slugs the recoilis pretty stout.Therecoil feelsmore then my 444Marlin anddefinitely more then my Remington model 7600 Carbine in 30-06 did whenshooting Remington's 150 gr.Core-Lokt ammo, which is the only ammo I ever fired in it. Ishot my friends Remington 11-87turkey gun. I fired two 3 1/2" turkey loadsthrough it and will never shoot a 3 1/2" 12 ga. load of any kind ever again. It was just brutal!
