I dump 'em in a big Dillon primer flipper, pick up the ones that are the right way, then flip the tray over and get the rest of them. Maybe marginally faster than shaking the tray to get 'em all right the first time, maybe not.
Don't listen to any of them. Get yourself a pair of colts in 45. If you shop around, that's $3000. Then get a new Winchester 73 in 44-40. That's about $1300. $700 easily gets you a Johnny Meadows ttn hammered shotgun. You're good to go.
