I have a desire to buy another H&R Hand-Rifle. I want it to be what I would consider a "big" caliber. I know that H&R is more or less gone now, but there are still several to chose from on Gun Broker and other sites. The 3 calibers I am choosing between are .35 Whelen, .444 Marlin, and .45/70 govt. Of these 3, which would be the easiest to reload and find components for? I know the Whelen is kind of the odd-ball of the 3, but I still think it is a really cool cartridge. I don't have a specific use in mind for it, but when has that ever stopped a gun purchase
