To the Chair of the State Committee of Defense of the USSR, comrade Stalin I.V.
Engineer Simonov proposed an anti-tank rifle that is both simply designed and powerful. During trials at NIPSVO, the following characteristics were recorded:
- Caliber: 14.5 mm
- Mass: 21.45 kg
- Length: 2220 mm
- Muzzle velocity: 1060 m/s
- Practical rate of fire: 15 RPM
The penetration of this rifle is sufficient to fight enemy light and medium tanks, as demonstrated in the following tables:
Range (meters) | Angle (degrees) | Armour thickness (mm) | Percentage of complete penetrations |
Production bullet | |||
350 | 20 | 20 | 80% |
Metallo-ceramic bullet | |||
100 | 0 | 40 | 100% |
200 | 0 | 35 | 100% |
300 | 0 | 35 | 100% |
700 | 0 | 30 | 100% |
700 | 20 | 20 | 100% |
1000 | 20 | 20 | 100% |
1200 | 20 | 20 | 50% |
Metallo-ceramic bullet with tracer | |||
100 | 0 | 50 | 100% |
150 | 0 | 50 | 50% |
250 | 0 | 40 | 50% |
200 | 20 | 35 | 100% |
250 | 20 | 35 | 100% |
700 | 20 | 30 | 100% |
800 | 20 | 30 | 50% |
The German anti-tank rifle is a good mass produced measure against light tanks at ranges of up to 500 meters. Simonov's rifle, on the other hand, has superior power, rate of fire, is simpler to produce, and allows infantry to independently fight tanks at the following ranges:
- 20 mm: 1000-1200 meters
- 30 mm: 700-800 meters
- 40 mm: 200-250 meters
- 50 mm: 100-150 meters
Additionally, Simonov's rifle is self-loading, allowing firing of 5 shots in 4-5 seconds in close range tank attacks.
I think that is is necessary to take action to put Simonov's 14.5 mm anti-tank rifle into production.

Was the Metallo-ceramic bullet put into production and actually used?
ReplyDeleteGuessing that's a fancy name to call "APCR"...
DeleteYes, the BS-41 had a metallo-ceramic core.
DeleteIt was a Tungsten Carbide core. Metal = tungsten, ceramic = carbon.

DeleteYes this is the APCR, the standard 14.5mm round (BS-32?) the non-APCR shot was 35mm @ 100 meters at 0
DeleteWhat kind of steel was this shot?
Hardness (BHN)?
Also I imagine this probably compared the PTRS with the German Pzb 39 as there are comparisons made above does this include a penetration chart? I would be interested in seeing that.
Due to limited amounts of available ammunition, very limited penetration data was obtained for the PzB 39. http://sovietguns.blogspot.ca/2015/08/pzb-39-evaluation.html
DeleteTY I saw that
