On examining and comparing the penetration of the Panther's KwK 42 and the Tiger's KwK 36, I've noticed that the Panther's gun isn't more penetrative than the Tiger's when using APCR ammunition; it actually becomes less so at longer ranges.

With APCBC-HE ammo, it penetrates noticeably more, but then evens out at about 2000 yards.

Having no wholly superior KE-ammo properties and an apparently shorter accurate range and weaker high-explosive shell (due to smaller calibre), can it really be called more powerful? I think that there was a reason for the astounding successes of individual Tiger tank crews driving the slow beasts.

Suspicious APCBC-HE charge...[edit]

The specs table says it was a mere 18 g of RDX. This seems very very odd, since even 20mm HE rounds used by the LW carried that much... typo, and it should read 180 g? Can someone who added the figure can cross-check? Kurfürst (talk) 23:49, 3 January 2010 (UTC)

I'd say it's correct. Citing from memory: Was an AP shot with a small explosive content intended to explode after penetration to kill the crew. --Denniss (talk) 06:36, 4 January 2010 (UTC)

Pzgr. 39/42 Mass[edit]

As far as I know the Pzgr. 39/42 was identical to the Pzgr. 39/40 with the exception of the 39/42 having a second driving band.

I think it masses the same as the Pzgr. 39/40 (6.8kg) and most other internet sources seem to reinforce this.
