14.5mm PTRS and PTRD

This is sort of a thought experiment for now.

I'm thinking of ways of improving these weapons. In particular I took a look at the bullets these fired. The bullet that was first used was the BS-32. It had a hardened steel core inside a softer steel sheaf. We called it APCR. In August 1942 a new bullet, BS-41, with a hard tungsten core, was accepted for service. This too could be called APCR. Since tungsten was rather rare and expensive it probably would not be the only round the gun crew carried.

What we do now is introduce a completely new gun type when the new BS-41 rounds came into service. So it only fires that type of round.
A better solution would to have some of the ammo as BS-32 and another percent the BS-41. I found someone familiar with E. Block weapons who said the BS-41 was for anti-tank use and the BS-32 for trucks, guns or half-tracks. I was thinking the new round could be 25% of the rounds available for the first 6 mos. after first introduced and then level off at at a maximum 33% after 1 year. Just a SWAG.

Since only one type of APCR is allowed for a gun, one of the two types has to be re-labeled as either APCRN or HVAP. Something that has the same variable penetration as APCR.

I do think these weapons need special 'consideration' regarding their capabilities and uses. But, really, the steel round was nothing more than what a 'copered-jacketed' round is to the infantry ammo. In other words, it was just a thin soft outer shell that hardly made up the diameter. In my mind; it is just plain AP.

As far as how they need 'specialness', they need to be appreciated for their mode of use. In most cases, they are used at very short range. But, the fact that the sights..even primitive...allow the targeting of very susceptible systems must be modeled. Easy to say, maybe hard to model.

A game would need to model periscopes and sights and cupolas etc.

On another site someone posted a link to a WOT blog page where different (somewhat dubious) dispersion values were given. One was a 12.7mm BS-32 AP round with a dispersion of x=.6m/y=.76m. If the 14.7mm BS-32 was anything like that don't see how it could be used for sniping.

my understanding is that ATR work (not sniping) was done at close range and just using iron sights could threaten periscopes, sights, barrels, cupulos and anything else. In other words, they shot at close range and high velocity and sights close to the barrel just minimized errors.

Interesting. That is one long barrel.
