Hey everyone. I’m new here and to hunting/bolt action rifles in general. I had a question about a Remington 700 .30-06 I just bought and was hoping someone would be able to help me with the manufactured year. I believe it’s an ADL because there is no hinged plate underneath. I know about the codes but I’m not sure if I’m interpreting it right. The first letter is “U”, which I know is not a month indicator. The next two are “PP.” I’m not sure if this means June 1967 or 1945. Here is a photo to help. “64” is also stamped next to it, if anyone knows what that means, that would help me too. Thanks.
