haha you heard wrong...i have an 870 express mag(3 inch only) amd with the extended tukey choke that came with it and remington bufferd nitro magnum 1 7/8th oz of # 4s i feel i can take a head off at 15-20 yds..the pattern was GREAT...at 35 yards it still tore upa papper plate pretty bad...id say change loads...i shot the same shells out of my mossberg 500 and a load of 6s and the 6s i barely made a hole in the paper the 4s patternd decintly...i love my combo now though..and that factory choke works great for me
