# Description

The 20mm Mg 151/20 has multiple rounds such as Ap-I and Aphe, the rounds itself are the same with the difference beeing the filler and a bottom fuze instead of a screw, because of that they shouldnt have a difference in penetration, but i was told that it might not be able to penetrate more than the 19mm in game do premature explosion with the fuze, but in that case it shouldnt have a drop of penetration on ranges further, so as long as the normal grenade can at distance penetrate more or 19mm so should the Aphe as a cap for example

10m 19mm

100m 19mm

200m 19mm

300m 19mm

400m 18mm

500m 16mm

( there between the 100m and 500m starting the drop off because it represents the penetration performance of the Ap-I but at no dictance can exceed 19mm) instead of

10m 19mm

100m 17mm

500m 13mm

Here for comparison the pet table for Ap-I

10m 25mm

100m 24mm

200m 22mm

300m 20mm

400m 18mm

500m 16mm

600m 14mm

700m 12mm

800m 11mm

900m 9mm
