I have a box of Remington Kleanbore .22 LR ammunition and am trying to identify what year it is made. It is a box of 500. pictures attached. It is wrapped in a plastic, and what looks to be masking tape (?). I haven't opened it, picked it up years ago. I did a bit of research and believe it is mid 1930s, but can't be sure because the reference material mostly focused on single boxes of 50. I'm hesitant to open it without good reason, to preserve the box and value (if any).
box reference website: https://cartridgecollectors.org/documents/Remington-Cartridge-Box-Dates.pdf
Thanks in advance.

Gents, thanks for the replies. I went ahead and had an unboxing party with the ammo, and found it to be in decent shape. The large box flap was not intact unfortunately.

NIB, I believe that they are (c) "BB" bottom. #7 flap. Copper cases. <- from the link you provided. definitely 1930s.

Overall, the condition of the rounds seems to be OK, there is some lead oxidation on the bullets, but that's no issue. There's one pic below of the smaller boxes in the larger box, where you should be able to see that it looks like the lubrication settled on the bottom. I don't know if that was simply years of storage, or a certain time where they may have been exposed to higher temperatures that allowed some (or all) of the lubrication to settle. If it is a time related issue, perhaps flipping old ammo every few months/years could assist in keeping the lubrication on the bullets. All just thoughts.

I'm going to have to zero this at a mile and see how it shoots :)
Also, on the inside flap it says boiling water is a good way to clean the barrel. I have done that in the past in certain places with gas guns (3rd party owned), and found it to be incredibly efficient in getting all the crap out of every cranny. I don't do it with precision rifles but is there any reason why it's not good when cleaning semi-autos?

Ole,
I believe the lubrication used on older bullets was a combination of wax and oil, when wax/oil are combined we call it Grease. As you said the lubrication settled. I would say a "portion" of the lubrication (oil) settled. Heat certainly may have been a contributing factor. I'm not overly certain the white is lead oxidation. I believe the white is dry wax.

You may know this but, boiling water is a black powder cleaning method. Remington wanted customers to get all of the black powder residue out of the bore.

I'm glad you are able to learn more about your old ammo. Thank you for those great photos! I read all of them. I like the two addresses on the box, one for ammo and one for guns. (y) :)

I believe up to the late 1920’s early ‘30’s a black powder/smokeless powder mix was used in 22 ammo even in some that had “clean” priming. The use of water to clean the bore prior to shooting the Kleanbore ammo may have been to insure the salts from this mixture was not trapped by the bullet lube and left in the bore?
