I guess I misread his post, so in fact the generalization was pointed at 22s as a whole as being unsuited for anything but coyotes.
Oh! nein you didn't!
this 200LB buck didn't seem to think he was too big for a 55grain bullet with horrible ballistic coefficient at 225 yards.
BTW, at 225 yards, this 223 ammo is going about 200 FPS slower than the muzzle velocity of a 5.7 so theoretically, given bullets with decent velocity and BC(for a 22) the 5.7 should make a passable deer cartridge at least within muzzle loader ranges.
