That makes sense, good call, ill give her some tlc
Any 870 made after 1986 except a wingmaster didnot have the chambers polished to the degree the old ones did
99% of the time if one hears of a jammed shell it is one of those with promo or cheaper shells in it
Some after 87 never have the issues others do but very common
Cheers
Fix the link
