The Penetration of the 6 Pounder (both the APHE and APCBC) seems curiously low. I noticed it seems unable to penetrate a Panzer 4 G even from relatively short range, when in reality the first tiger (A considerably more well armoured tank) knocked out by the western allies was pierced by 6 Pounders at medium range. Penetration tables are notoriously unreliable, but this might be worth a second pass?
