Thanks prm,

That's the other thing. My 99/300 is 24" and hangs and handles well. So I was considering that if going to a slightly larger bore (.338/.358), barrel weight would be less (if same contour). Plus, when running irons, the extra radius may be advantageous.

Guess another way to gain some speed would be to run a 99C set up (magazine) for the 284 Win case...necked to 338/358. In essence a short 338-06/35 Whelen.
I'm a little quicker with follow ups when running a lever...was my thinking
