Looky what came home from GunBroker! A 1974 Walther PP Super in 9 Ultra. Looks brand new, amazing! Always wanted one of these but ammo has been an issue. So I did some research. Loaded up some 9x18 Mak cases sized in 9 MM Dies with .355 90-95gr .380 bullets, worked like a champ! Feed, cycle, eject like they were made for it, fit the chamber perfectly. They end up looking like 9 Mak rounds cause the magazines are made for truncated bullets not round nose ones......so you have to seat round nose FMJ's little deeper than normal. Using .380 load data. Dimensions are generous enough that Mak cases fit the breech faces on ALL my .380's. CZ, 82/83's Sig 238, Browning BDA, Walther PPK, Colt 1908 and even my Husqvarna 1907. They won't chamber all the way in the .380's cause the case is tapered and bigger in diameter. Didn't anyone ever try using Mak cases sized in 9 MM Dies? No split or bulged cases like you would get using 380's in the 9 MM Ultra. Can't believe the gun looks brand new, 1974! Started reloading .380's and everything else since 1982ish. You almost can't tell the difference between Mak cases sized and loaded with 90, 95 JHP's and cast 100 gr bullets over the real 9 Ultra ammo! The gun can't tell the difference between Fiocchi 100 gr FMJ's and my reloads using 9 Mak cases sized for .355 bullets!
