"SAV m/43 Armour Penetration?" Topic

I asked this earlier in an on-going thread, but perhaps a fresh thread of its own that pops up on the front page may help find an answerer….

My google-fu has failed at turning up armour pentration abilities of the 105mm gun on the SAV m/43 (Sweden's cute Hetzer-like assault gun). The only thing I could turn up was this cryptic data line from World of Tanks:
10,5 cm kan m/44 sav Penetration 65/110/53

Can any WOTters translate that into actual ranges?

Specifically, I'm trying to find out what the Kan m/44 can penetrate at 500m if anyone has that info.

This page:

ointres.se/sav_m43.htm

indicates that AP shells were available. Unfortunately it also says that it was a new gun design. Barrel length is 21 calibers, vice 22 calibers for the kan m/40 10.5cm, so if you can find penetration data for that (more common) gun, you can estimate the values for the m/44.

Thanks — that's a very helpful page!

That WOT stat line reflects penetration for different ammo types:

regular/APCR/HE

Not sure what range this pen is supposed to reflect but then again WOT is not exactly a hard core combat sim.

Maybe this will help:

The Bofors 10,5 cm kan ikv 103: the gun on the ikv 103, firing a mid-60's HEAT round had a penetration of about 350mm.

The German 105 has a longer barrel so better penetration than the Bofors.

In the Reference section there are official hand books that you can download showing all of the ammunition for each of the guns. There's an actual solid-shot AP round for this cannon, and it's very odd. So short that the length and diameter are almost identical! Unfortunately, I couldn't find penetration numbers.

It looks like a projectile mass of 11.67 kg, at a muzzle velocity of 475 meters / second. This page:

gives an estimated penetration of 66mm. YMMV.

Well that pretty well matches the WoT number of 65.

The US 105mm/L22 M2A1 howitzer has a muzzle velocity of 472 m/s. That is for HE. AP would weigh a bit more so it's velocity may be less, but the US had no AP.
