varmit_master,
I've been using 700X since 1970 or so. Mainly for 12 Gauge trap and skeet as I use a 20 Gauge for Upland and the only Hull that I know you can use 700X in is the Federal in 20 Gauge. Unfortunately, I never get any Federal empties so...
You can use it in Winchester AAs up to 1-1/4 oz. loads, Remington 1-1/8 oz loads, Peters 1-1/8 oz. loads,Fiocchi 1-1/8 oz. loads, Federal 1-1/8 oz loads, and Activ 1-1/8 oz. loads.
Very versatile, fairly clean burning, economical and the patterns I get are outstanding.
I'll take it off your hands...
