A 4 digit Lot Number, 4333, is probably corrosive.

That being said, if the price is right, buy it and shoot it. Just clean the firearm with HOT soappy water after each use.

On Fulton Armory's Garand info page, they link to info from TM 9-1305-200, 14 June 1961. That lists the FA starting lot number for non-corrosive primers as 4149, Oct 1951.

Thank you. Yes I saw the 4149 Oct 1951 myself. As I went to get my ammo there was also a tin can that when opened it made the sssstttttt sound as it was sealed and there are 220 rounds in it from Saint Lewis armory. Head space SL 42. 1942 I dont think I will shoot this ammo.

The best way to check is by the date on the headstamp on a case. There is no way to know when lot numbers start and stop and how often they went back to lot number 1. But a headstamp date will tell if it's corrosive or not.

and go ahead and waste 1 round by pulling the bullet and testing the primer for corrosiveness

Pull a bullet, dump the powder, load the primed shell into your rifle, hold the barrel end a few inches away from raw steel and fire. Be sure to wear ear protection & safety glasses. If the steel is rusting after a couple of days, then the primer is corrosive.

Here is a link to a listing of first production lots of non-corrosive ammo. Any years or lot numbers below these will always be corrosive. Print it out and carry it with you.
