The man said he was thinking of non-magnum loads, did you actually read his posting? By your philosophy, a 1 1/4 ounce high brass #6 would be too much for the gun.
Keep yours in the closet, take them out only to shoot clays and preserve pheasants on warm sunny days, then wipe them off with a diaper and store them away again. Like I just said in another thread, different strokes for different folks.
I'll lay in the snow with mine, waiting for geese to decoy while icicles hang off the end of the tubes. I'll call in and kill my birds clean with a good stiff fowling load just like the ol' boy that ordered the gun would have used. You have your kinda fun and I'll have mine.

P.S. to doubleshot: PM me your address and I'll send you enough shells for your first 10 blackducks with that Hopkins and Allen.
