Greybeard,
Thanks for the information, it helped me make up my mind. I did a lot of reading, and searching, and your right, it doesn't seem worth it. I don't think the .350 Rem.Mag., would have a problem keeping up with the 35 Whelen, but this rifle isn't the platform for it. Ruger has the Mod. 77 listed at Wally World as being chambered for the .350 Rem. Mag. for $463. On the other hand, the .338 Win. Mag. is also listed in that rifle at the same price. In the long run I think I'd rather have the .338 Win Mag. if I'm to get a new medium bore, wouldn't you agree?
Thanks,
Don
