The 35 Whelen is a great hunting cartridge. I can remember years ago, many people converted their old 06 with shot out bores to this caliber.
Remington made this a legit round and I considered a bolt gun in 35 Whelen around 10 years ago but could never find a rifle in this cal for sale anywhere I lived at the time.
The Whelen, never seemed to take off. In fact, practically every introduced 35 cal appears to have never gained favorability except perhaps the 35 Rem. Americans are obsessed with 30 cal.
Providing one reloads, ammo would never be a problem as there plenty of 06 cases around.
