It's 322X (four digit), looked fairly hard but still cannot come up with date of mfg. listings.......any help? Thanks, r in s.

Your XP-100 rifle started life in 1963 as a XP-100 pistol in 221 Fireball. When it was made over into a rifle is anybodies guess.

Thanks Nitemann, where did you find your source (if I may ask).......'63 great year, graduated college back then, gas was $ .25. r in s.

It's posted over on the Specialty Pistols web site. Lots of XP shooters over there, including me. 63 I was 4 years old but still seams like a long time ago.

if you go to remingtons site go to questions and answers and you will find the part that says ser# enter the info.send it about a week or two you will get an e-mail will all info. rate of twist,date of manu. and it is free,they might even replace the safety for you.

Ray, I know the rifle you are asking about!! I'd bet it's in a BLUE STOCK!! It came to me from from Florida and was part of an estate of a BR shooter. Now just stoke with H-322 and 68 grain Moly Bergers and have at it!! GHD
