My wife shoots a SKB 150 20 ga and we usually use light reloads. Today we had several problems where the 2nd barrel wouldn't fire. I am pretty sure it is due to the light reloads not tripping the inertia system. The gun doesn't have a recoil pad so that isn't the problem.
Has anyone altered or adjusted their similar gun to accommodate light loads. At the end of the round she tried my 20 ga W 21 and hit 2 of the tougher targets on the course and said wow it swings itself.
My daughter has this same problem with a 20 gauge Browning Superposed that she's been shooting for several years. That gun is about the same weight as your wife's Model 150 SKB.
She's 5' 8" and about 130 lbs. The 3/4 oz. loads I loaded for her almost never trip the inertia trigger. Even 7/8 oz. loads don't work all the time.
She's moving to a 28", 12 gauge Superposed this year; we'll see how that works. I also have a 2nd 28" 12 gauge Superposed on the way - this one a Fabrique Nationale Grade C1 - that was made in 1975 and should have the mechanical trigger instead of the inertia trigger. One or the other should help the problem, and longer barrels and extra pounds should smooth out her swing.
