20 mm anti-tank gun? What, water tanks? 20MM wouldn't penetrate the armor
of early WW2 tanks!

The various big caliber (13.2 German, 14.5 Soviet, 20mm Swiss, Finn and German) AT rifles came off the drawing boards before WWII.

I've fired a 20mm.

It wasn't something that I'd want to do on a regular basis.

At 90 degrees at 100M the Lahti could penetrate 30mm of armor.

Which could penetrate many of the Soviet Union's tanks during the Winter War such as the BT series.

T-34 and later tanks had 50+ frontal armor but the less armored sides and rear could be vulnerable.

but a shot to the tracks would imobilize it allowing for follow up shots to possible be sent into side or rear of tanks. or to block a road or allow other troops to over run it.

At one time there was one stored in the property room of the Kern County Sheriff's office. Guy had to turn his in when the 1968 GCA went into effect.

I think its a really cool firearm, truly a shame that we can't have DDs here in Cali.

Cool thread on them recently: http://www.calguns.net/calgunforum/showthread.php?t=252949

Another 20mm that is really cool is the Croatian RT-20, which was kind of like a small recoilless rifle:

Anzio Ironworks had a Ca legal version at SHOT. It was their new 20-50. It's a 20mm necked down to .510".

It would penetrate plenty of the early WW2 tanks. Ever see a Panzer MK1 or 2? Early soviet tanks didn't have very think armor. Neither did our M3 or M5 tanks.
It was also good for personal carriers and other vehicles.

Honestly, the only thing about 20mm and up rifles is their payload capability for HTI missions. Being able to get the round on target is one thing, but if you're shooting a bullet that has explosive API capability you're more likely to defeat an HTI target than just poking holes in it. I think that alone is the number one reason why .50BMG rifles are in wider military service than smaller, yet ballistically superior rounds (ie Mk211). The problem is that with .50BMG and especially 20mm rifles the minimum size/weight/mass involved for the platform is substantially more than the smaller rifles that are better at getting a bullet on target at distance.

What a round might do, against a piece of armor plate,stationary at 100 meters, is one thing. Against a moving tank at various angles and ranges, not likely. There were Numerous reports of 37 MM's from M3's,M5's and AT guns
getting solid hits on Even German light tanks and having no effect.

That would be way to much fun to have in this state. Anything over .50 you need a Destructive Devise Permit. Don't know the name of the gun but a friend has a German 20mm AA gun
