I'm looking at getting a contender with a couple barrels. The first would be a 410 for snowmaching and bird hunting. The second I'm not so sure about. I'm looking for a round for varmint all the way up to wolf hunting. I know they make a .223 do they also make a .22-250 for it? Which would be a better choice? Also at what range could I except to shoot decent groups out to?
