Hi Scrapper,
The manuals are all on the conservative side for the Whelen due to all the old rifles still in use that were built way back when the round first came out. It'll do much better than what current manuals list, with no problems. It's kinda like the .44 Special and .45 Colt. There are a lot of them around that were built back in the early part of the 20th century that wouldn't be safe with some of the loads that are being used in modern weapons. Plus, the Whelen wasn't entered into SAAMI until Remington legitimized it in 1988, so chamber dimensions of early guns are all over the place necessitating the need for factory loads be kept to lower chamber pressures than would be the case if it had been invented in the last 20-30 years.

I have been loading the Whelen for22 years now, and it is a very easy round to work with.

The .35 bore is largely neglected in this country, what with everyone being speed crazed these days. That's too bad since it is a heck of a round that has mild recoil considering what it'll do.
