Talk:Ordnance QF 20 pounder

From Wikipedia, the free encyclopedia

[edit] Performance

I've read a couple of times that the performance of the 20-pdr is "about twice that of the 17-pdr", without much by way of explanation of what's meant by that. Twice the penetration at 500 yards? The same penetration at twice the distance? If anyone could expand on that claim (or debunk it) please do so! Chris 22:12, 23 July 2006 (UTC)
