actually 110. The M9 bazooka did lived up to its factory performance however
Another problem was the Faustpatrone 30. If fired at a sandbag, often it did not penetrated the armour. This led to allied tankers throwing sandbags and stuff on there tanks
Problem was, the Panzerfaust 30 had no problems with these sandbags whatsoever.
As for anti-tank grenades, the russians got some very good AT grenades out.
Like the RPG-6. Wich detonated on impact, and often also landed on the cone. Factory settings said 120mm, it could penetrate up to 100mm often. However it had a small extra little thing wich was a effective fragmentation radius of 20 meters. Wich adds to its multi-purpose usefullness
It can supplement weapons like a Panzerfaust/Bazooka but it can never replace it with the same effects.
