I hate being a nay-sayer, but my wife has a .243 in Wichester featherweight mod. 70. I've taken one deer with it and so has she. They did go down just not as fast as with my '06 or her .270. I put two in the same hole with two different exit wounds right behind the point of the shoulder. They just didn't go down like I appreciate. I feel it's a better 'lope or 'yote gun and just a bit small for deer. IT WILL work though. I used 90 gr handloads.
