A Remington 722 is perhaps the most cost effective way to obtain a quality .257 Roberts, they're well built rugged rifles. You got a great deal on the rifle, welcome to the .257 Roberts club it is an easy cartridge to reload for. I was fortunate to find a pre'64 Win. M/70 Featherweight
that the previous owner rebarreled to .257 Roberts using a Douglas barrel turned to match the original FW profile.
