Hi Daz,
I got a full case of these for 70!
JC has the full case for sale at 300 I think!
Anyway,click here for more info on the 45mm round.

Apparently none of these rounds have the primer as they were supposedly very difficult to make inert.

Hi Daz,
There is some more info for you here and a picture of a sectioned round.

correct, there were, I believe, 2.5 thousand released to Ben Junier plus several of the guns. None had primers. But look out for the solid brass drill rounds, there were a few in amongst them. More recently, the gun handbooks were released in some numbers and are 'as new'. I'll dig one out later and post a photo. Dave
handbook is A5 size and the outer cover doesn't give much away - I've opened out one of the fold outs.

It appears to be a 45mm. APHE (Armour Piercing High Explosive) round, which had a notorisously poor performance against German and Axis allied armour. It had a dual purpose role against light fortifications and emplacements.
It was also produced in 20mm., 37mm., 57mm., 76.2mm. , 85mm., 122mm. and 152mm. being the standard Soviet anti-armour shell type from the 1930's to well into early WW2.
The flawed concept was that the impact would start a delayed fuse in motion, the shell would penetrate the armour of the target and then explode inside the vehicle.
By 1939 all nations, apart from the Soviet Union, had abandoned the obstelete APHE shell type and developed solid shot type kenetic energy rounds, due to the increasing thickness and quality of AFV armour.
Another problem was that the APHE shell was 19th century solution to penetrating and nflicting damage to warships clad with hardened steel hull, and in WW1, early primitive AFVs.
However, in the 1920's, AFV armour changed from hardened steel to nickel copper iron based armour plating (on average 70% nickel, 15 - 20% copper, as low as 5% iron and a mixture of chromium, vanadium, molybednium and other metals blended in. more commonly known as homogenous armour or if the outward surface is further heat and chemically treated, face hardened armour.
A British range test, in the 1920's, compared the penetration of the German 13mm. AT rifle against the old hardened steel armour and homogenous armour. The former could be penetrated up to 64mm. at 100 yards whilst the latter only by 21mm. at 100 yards.
Further comparisons with German 7.92mm. AP bullets gave a maximum penetration of 39mm. for the hardened steel and 13mm. for the homogenous armour plate at 100 yards. I was noted that half an inch of hardened steel armour only gave a 62% chance of resisting the bullet at 100 yards, whilst the homogenous armour plate gave 97% chance for the same thickness.
When fired against this newer type of armour, APHE shells tended toi break up without exploding on impact twhen fired from the new technology high velocity anti-tank guns, it had veen discovered.
To add to the already poor performance of the projectile versus armour, the muzzle velocity was propellant was black powder with a nitro-celluose primer.
According tyo German range tests, the round could only penetrate a maximum of 52mm. of vertical armour at 100 metres abd was totally incapable of even penetrating the 50mm. of frontal armour of the Pz.IV F or StuG.III. tanks bering fielded in 1941.
The probability of a first round penetration for a soviet 45mm. :46 firing APHE is given as only 2% at 100 metres against 50mm. of square on rolled homogenous armour plate.
In 1941 the majority of Soviet tanks and anti0tank guns used this type of obstelete shellm which resulted in the whole sale slaughter of Soviet armour in pretty much one sided battles with German and Axis allied tanks firing superiour solid knetic energy type armour piercing shot.
By 1942, with the help of allied proppellant technology assistance, APHE shells were being phased out in favour of solid "Arrowhead" knetic energy type shot projectiles.
