I got a phone call from a friend in my unit a few minutes ago... and we are going out to the test range in a week to "mess around with" a anti armor rifle called the RT-20... he said its made in Croatia. Its a 20X110mm "Hispano" Caliber and ive never really heard of this before.
Im wondering if the 20X110 "hispano" is any different than the regular 20X110mm rounds... Maybe the projectile is different? Or loaded to different specs. I know the RT-20 is one of those funky "reciolless" sniper rifles... it has a tube above or on the side of the barrel in wich some of the powder charge travels through (just like any gas operated semi auto) but instead of operating the action... it just shoots it out the back of the tube into the air to counteract the reciol. Anyway... Any information on the 20x110mm Hispano caliber will be appreciated. Thanks.

The 20x110 Hispano was originally an AAA round. And it was also one of the most widely used 20mm cannons on WW2 aircrafts.

Ehm..as far as I can remember, 2000gr projectile with a muzzle velocity of about 850m/s+. That should mean some 45-50000J at the muzzle....

I hope we get to see some pics!

Are you really allowed recoilles rifles in the states? Imagin the damage you could do with those "pills".. 8)
