If you go to page 1 of this thread, you'll see the serial numbers of rifles that people have, listed by the date that corresponds to the barrel date codes (from the following link).Jackalope wrote:My father recently passed away and I'm trying to figure out his collection. He has a 722(A) (stock is as plain as you can get) which has definitely been rebarreled but it is in 22-250. From what I have gathered this was never a production caliber. Remington was able to give me the manufacturing year of 1956 but no month. Serial number is 3762xx.
Any help would be appreciated. Thank you.

Based on the part of the serial number you provided, it would probably fall in or around the following two numbers.
3762xx 722 244 X B 12/55
3768xx 722BDL 222 L C 2/56
Without the original barrel, you don't know what the original caliber is......however, it was obviously a short-action caliber with an '06 case head (that would fit the .22-250). So, I would guess it might have been a .244 Remington, .257 Roberts, .300 Savage or .308 Win. If I had to narrow it down further, I would guess it might have been the .244 Rem or .300 Sav. Due to some less-than-complimentary articles by some of the gun writers of the day, the .244 caliber fell out of favor and the 300 Sav. was losing popularity by the 1960s due to the popularity of the .308 Win. and many .300 Savage barrels were rechambered to .308 Win. So, my deductive "guess" would be that it was originally a .244 Rem.
The .22-250 cartridge was "legitimized" by Remington in 1965.
If your rifle has a genuine Remington barrel (with all the proper identification stamped in it), you should be able to see when that barrel was made from the barrel date code. If it was removed from a Remington rifle, then you'll know that the rifle was re-barreled after 1965. If it is a non-Remington barrel, it could have been done almost anytime after 1956 (since the .22-250 cartridge originated in 1937)
