I've been shooting a 15" contender in 300 savage for right around 17 years now. I have loaded it hot but since have backed off quite a bit.
Using Hornady 130gr bullets, I chrono'ed my load at 2460fps. With the 1/2 to 3/4 inch groups I get with this load, that's fast enough for me. It's worked great out to 150+ yards on whitetail.
I know there are many new wildcats out there in 30cal., but looking at the ballistics, I can't justify a new barrel for nominal or no gain in velocity or accuracy.
So many calibers, so little time. That's why there are so many shooters, all the calibers get used by someone. To each his own.
Good shooting,
HL
