Here are a couple of unusual 40mm Bofors items that I thought someone might like to see. The upper one is the T2 spiral wrapped steel case loaded with a Mark 2 Mod 1 projectile. No primer and unfortunately it has no headstamp. The lower one is an experimental round, or the biggest "wildcat" hunting load you could want. The projectile is the M99 TP. The projectile is dated 1946 and the case 1944, but that really does not mean much. This was loaded for a test, if I recall in the early 60's to develop a high velocity gun system. Somewhere I have a report talking to this loading and the fact they first loaded the 20mm frangible TP projectile. The stress on firing was so great that the only thing that left the muzzle and went down range was the rotating band and a spray of powder. Then they went to the steel body M99 for obvious reasons. Initially they still had some over pressure problems though because the first firings reportedly blew the projectile right out of the rotating band and they both went tumbling merrily downrange. Oh, the joys of experimental range work!
