I'm new to this site and I really like the NEF/H&R idea. I bought a H&R singleshot rifle in 30.30 at a gunshow with the intention of having it rebarrelled. Cant find a model number anywhere. Got it cheap, not new but not in bad shape either. Unfortunately according to the H&R 1871 website it can't be rebarrelled at the factory because its serial number starts with B instead of N or H. Guess I 'll have to buy a new one in some caliber I want and keep the serial number thing in mind for the future. Anyone rechambered one of the these rifles. Could do something like the .307 Win or even 30.30Ackley Improved to give the old girl a little more juice and stay with a rimmed cartridge. My factory rebarrel request was going to be .308. Found a nice Ultra Varmint in 223 wants $225 used, but then I just saw Walmart's price at $230 new. Any help would be appreciated. :gun4:
