Great gun for deer sized game. Some will say it is undersized, but they have never hunted deer with it. I would stick with the heavier grain bullets (90 to 100 grain). I started out with the .243 and then went to the bigger guns for a few years, but after realizing that the big guns didn't kill them any better, I went back to the .243
Traditions only last if you pass them down to your kids!
I shoot 100 grain corelokts out of mine. Killed many deer with it, from point blank to just over 100 yards. Longest track job was 20 yards. Excellent cartridge if you ask me. In the thick stuff, just pick a window to shoot through!
A .243 is plenty of gun for a deer. I started with one and still use it as my back up.
George Thacker who started the PA Gunsmith School years ago claimed that it was a much better brush gun than most hunters ever realized. Don't know if its true or not, but that guy forgot more about guns than most of us will ever know.
I've used one for the last 17 years and wouldn't think of changing to a different gun. Recoil is lighter than most other deer caliber guns. It shoots real flat for good distance shots. Its definitly enough gun for a deer when bullet is placed properly.
I've watched 11 deer hit the dirt between my 2 kids. About half dropped at the shot the rest didn't make it out of site 50 yards max. Rem. 100gr. or Fed. Fusion 90gr. both worked great though the Rem. sometimes didn't exit.
