Xausa, 740/760 series rifles in .30-06, not 870. There are a few folks who swear by those rifles {a good friend of mine in particular} but as you say, heavy loads in .35 Whelen in a 760 would be unpleasant, especially with the 300 grain bullets. Of course, there is no readily available 300 factory ammo loaded, and the 200 and 250 grain bullets, frankly, do nothing a good 220 .30-06 load won't do.

But then, Remington ceased production of their superb 220 corelokt bullet in .30 cal, so we know how popular it must have been...

One of the things about American gun designers and Remington in specific that has always annoyed me is their marriage to slow twist rifling. No cartridge better displays this thinking than the .35 Whelen.

As for myself, I have always wanted a .35 Whelen built on a 1917 action {the P14/M17 is just about my favorite action tho I don't own one anymore}. And now, using the methods I've had success with resizing bullets from .375 to 9.3, filling the heavy gap in .358 bullet lineup would be a cinch using 9.3 bullets.

I sold my old Winchester 1917 to a buddy...I wonder what he wants for it...
