I finished loading the case of 124-grain FMJs for my 9x19 pistols- Glock G45, Beretta PX4s, and Walther P99Cs. OAL was 1.13” and they all dropped out of the Walther’s chamber which is the tightest among them. I’ve got enough primers left to load about 1k of the 124-grain coated lead RNs I have. These are the new style without a lube groove. I had to shorten the OAL to 1.06” to get them to work in the Walther’s chamber, and they’re still slightly sticky. I reduced the powder charge from 5.5 grains of BE-86 to 5.0 grains and got 1086 fps compared to 1118 fps from the FMJ load. My target velocity was 1050-1100 fps so I’ll leave it there.
Case mouth dimension for 9x19 is .380” and my taper crimp die is set at .377”, so it’s definitely the bullet that’s requiring the shorter length.
Just an FYI if you switch bullets and load for different guns.
