Rh-202 Autocannon in GURPS

Note: I wrote this having overlooked that the Rh-202 has already been given GURPS stats in Hell on Wheels in Pyramid, Volume 3, Issue 53. The numbers in that article differ slightly from mine, and are probably more accurate.

Rheinmetall Mk 20 Rh-202, 20×139mm Hispano (Germany, 1970-1976)

The Maschinenkanone 20 is a multi-purpose autocannon, used against both aircraft and surface targets from a variety of platforms. It uses a combined gas and blowback operating mechanism with a differential recoil system. It is available with either a single or double feed. The double feed version takes 4 seconds to switch between the two belts.

In addition to HE (in table), common loadings include API-T (Dmg 7d×2(2) pi+ inc) and APDS-T (Dmg 9d×3(2) pi+, Range 3,200/12,000).
