I am glad to hear somebody else has a fondness for the advantageous, sloping taper of the .375 H&H.

And looks!

I have always prefered the looks of the long taper of the H&H case over the short dumpy garbage can {ash bin...} shape of the current short mags.

A .375 H&H necked to .35 would be a winner, too, NOT Sundra-ized but rather slopie just like the original H&H.

If I ever do get a .35 Whelen, it will have a quick twist for long, heavy bullets. The Remington slow twist rifles never have appealed to me much and tho I am not aware of any 300 grain .358 bullets out there, there are lots of 286 grain 9.3's and even heavier that could be sized down for use in the .35, Whelen or G&H.
