i didnt realize the lil 20 gauge was a thumper,i bought a mess of 3"winchester super x 280 grain 3/4 oz slugs 1800 fps and muzzle energy of 2359 lbs now the 30/30 150 grain powerpoint shows 2390 on velocity and 1902 of energy at the muzzle,the 20 gauge throws twice the weight and still retains 1800 lbs at 25 yards-1208 lbs of energy at 50 yards,i know its a lot shorter ranged then the rifle round.i was told a 20 gauge slug is like a .444 marlin up close.impressive for the lowly shotgun round.im gonna make my pardner into a tracker and cut the barrell and add some better sights.
