105mm Door Stop

[bacarnal]

Gentlemen, I'm trying to get some info on the 105mm AP. It is marked on the top (sintered iron??) rotating band with the following: KVS-S-S-63-105MM-T182E1. Length of the round is 10.75", weight is 33lbs, and has double rotating bands that appear to be, as said earlier, sintered iron. Thanks, Bruce.

Bump. Maybe Pictures will help. Cheers, Bruce.

Let's bump it again and see if anything happens.

From what I have found so far it was experimental during the development of a new main battle tank leading up to the Abrams

2976 ft-tons* The ammunition development was terminated for the T140 series of guns prior to completion and the test data were incomplete.The T140 and the T140E2 guns were intended for use with an automatic loader and were mounted with the vertical sliding breechblock moving up to open anddown to close. The T140E3 was mounted for manual loading with the breechblock moving down to open and up to close. The ammunition for the T140 seriesof 105mm guns was assembled with the T43 cartridge case

Thanks, ordman. Now where can I find the casing:bigsmile:. Cheers, Bruce.

 

[charley777]

Thanks, that's very interesting.
Are the actual dimensions of the cartridge cases given in your reference?
There will be some of us in the BOCN community who collect such information, as well as the actual ammunition (-:
Greetings, Charley

 

[ordman]

I haven't read the entire transcript <br>
Though the casing information may be buried in there somewhere<br>
Now i got to do more homework geeez<br>
If i find something I'll post it

Leading up to the Abrams? Must have been waaay down the chain, we stopped using T numbers in the 1950s. ?? It would have seemed more likely leading up to the M60 - ?

True
R.P.Hunnicutt - A History of the American Main Battle Tank Vol.2 - Abrams
is a chronological history of the development of the American main battle tank from the M48 up to the M1
At 300 plus pages it's some intense reading if your interested in the engineering aspect of tank and weapon developement
in the post world war two and cold war era.
