Hi, I've been shooting GG for probably 20 years and have both. Really not much difference for most shooters. Jimmy Spurs will talk you out of short strokes all day long. Shorter hammer travel requires heavier hammer springs all things being equal, so more effort to cock. I alternate cocking. If you double cock it may be faster. Sooo..... who knows for sure.
Thanks Jack as I'm not an expert on the finer points of the conversion possibilities. It will work on an 800 convertible. You could talk with Jane at Ponsness as she knows everything.
I have used most of all the ones mentioned and have settled in with Alliant Extra Lite for our lighter shotgun loads, 3/4 oz and Claybuster wads. You hit 'em, they fall. Good reloadin"!
