In a recent posting, one member mentioned, "I have a Mossberg that has jammed, but it's always because I short stroke it, not because the gun itself malfunctions."
It got me wondering: We see all sorts of dimensions in shotguns' specifications, is the length of stroke ever given? Does one model have a significantly longer or shorter stroke than the others? Are side ejectors strokes typically shorter, or longer, than bottom ejectors? What model has the shortest stroke? Of course, this assumes guns with equal cambering -- we won't compare the strokes of a 3 1/2-inch mag with a 3-inch or 2 3/4-inch chambered gun.
What have you got (including its nominal chamber length) and how long is its full stroke?
For the sake of this comparison, for the full stroke: With an unloaded gun, measure from the muzzle to the front of the forearm with the action closed while exerting forward pressure (to take up any slack), get a second dimension with the action open while exerting rearward pressure. Subtract the first dimension from the second for full stroke. If it's raining, and you have nothing else to do, repeat this several times and calculate the average.
