Why does my 870 keep doing this?
It happened the other day after one shot and jammed my shotgun up while 2000 mallards were circling overhead. When I got home I pulled it all apart and stuck it all back together again. This morning I shot one shot while walking the river jump shooting. Luckily I killed one with one shot and it jammed up again.
I am shooting the remington hypersonic steel 3" 1 1/4oz of #4s which are rated at 1700fps. It's never happend with any other load but these. It seems that when I shoot! the recoil is forcing the gun back and the shells in the magazine are moving forward compressing the mag spring, plug, and cap together. Any ideas? Is it just too heavy of a load or do I have another problem to sort out?
