good question...i got my turkey gun as a birthday present from my dad and it shots better than any gun ive seen yet...this year i will count the pellets and tell you guys...but at 20yds a paper plate was pretty tore up...at 15 i bet a turkey wouldnt have head if i shot..and 20 it would be pretty messed up...35 it patterend better than my mossberg 500 did at 20! the mossberg had like 8 hits in the kill zone...my gun now is a 870 express mag turkey gun with a 21 inch barrel and the extended remington extra full choke..i dont need no 3 1/2 inch shell!! i cant wait to goto a turkey shoot and rock them old guys worlds!(im 15 most any guy is older lol) i didnt make it this year...i doubt my gun can get much better and if it was id have to scope it so i can shoot it like a rifle...but if oyurs is patterning bad with everything im sure the mods can only help...good luck
