    17 Pr APC-T

    I didn't look on BOCN threads, it must sure be in, but I have a picture where you can see your projectile. Also Blackwatch wrote, it's an 17 Pr APC-T (center projo on picture).

    Thanks for showing the photo. The cap has an unusual profile, its longer than the normal 17 pounder APC. Are there any stampings on it other than as shown in the photo?

    Thanks everyone for the info. I see the difference also between the cap of mine compared to the one in the photo. Mine is not rounded the same as the example Yoda has, instead mine is straight edged for about 20mm before it starts to round towards the top. The cap length itself measures 75mm in length. Besides a 10 stamped on the lower part of the cap, there is only 9687 stamped on the bottom. I see no other marks even after a nice clean up in the evapo-rust. Only black paint which (whats left) seems to be original.
    Thanks, Shaky.

    Thanks I can't help you with the meaning of the stamping, 17 pounder for sure but possibly a development round.
    Nice item though.

    Hey cheers. I kinda figure post ww2 compared to the other examples Ive seen elsewhere but who knows. Ive had it sitting with two other sherman rounds, an original British solid shot, and a super sherman POT 75. Somehow I figured it would fit in here somewhere. Could someone tell me the case size for this? I understand that some of these projectiles were also used with the 3 inch AA cases since some of the new 17pdr guns were too big to refit into some tanks. Therefore the true 17pdr had a higher velocity than the old 3 inch guns. I was led to believe that the cases for the 3 inch were shorter than the regular 17pdr, but the 3 inch case I have doesnt seem to be a great difference in size. Id like to say its a round for the Canadian made Ram. Why not ? Regardless Ill be keeping my eyes open for a 17pdr case. Thanks for the help again, SHAKY

    The Comet was the only tank to use the 77mm gun. This used 17 pr projectiles with the old 3" 20 cwt AA gun cartridge case. 3" cases are easier to find than 77mm cases but though the same dimensionally, the crimping is different.

    Your 3" case is probably a US 3" case and though a similar length to 17 pr is a slimmer case. These were used in M10 tank destroyer.

    Ram only used 2 pr in the Mk1 and 6 pr in the Mk 2. There were a few converted post war to 75mm, these used standard Sherman type ammo with the M18 case.

    The case shoulder is also different. It's a lot more rounded on the older 3" cases. The 77mm cases have a more angular shoulder.
