ok, rick, i'm not putting the 30-30 against the .243, that was just an example.
i'm not going to get into another .243 discussion either. its pointless. everytime this argument comes up, all i hear about is how many deer that someone has shot with their .243. (incidentally, the .243 has many years to go to match the number of deer shot by the 30-30, at least up in michigan.) that's not the point. the only way you'll get a .243 to expand more than a 30 caliber bullet is through fragmentation. if you're comfortable with that, go ahead. i do not like fragmentation because it reduces penetration, and contrary to your experience, exit wounds bleed far more than entrance wounds. and why is it that every .243 fan talks as though deer are never wounded with it - they all die a quick death?
if all you ever do is shoot broadside through the chest, why limit yourself to the .243? hell, use a .22-250. i mean, you're only talking .02" diameter difference. and if you buy one with a faster twist that the standard 1:14", you'll easily stabilize those 70 and 80 grain .224 diameter bullets. if you're only ever shooting through the chest - practically ANY gun will work.
so congrats on your deer. shoot whatever you'd like to shoot. i'm not advocating that anyone slam bullets into deer from all angles. i just like to carry a gun that makes me feel as though, should the errant shot arise, be it my fault, or some unforseen circumstance, i'm carrying a little extra insurance. straight line penetration through bone, for example. for those reasons, i like something other than the .243.
what is it with this site that no one wants to concede that there might be advantages and disadvantages to choices in gear, particularly guns?
just my opinion, i still have the right to that, don't I?
