I have been reloading for little over a year now. I started with 9mm and had great success. I began with using 115 grain FMJ bullets behind 4.8 grains of Hodgdon HP-38 powder. Worked great!! Moved up to 5.0 Grains of powder with even better results!! I had great accuracy and no failures to fire, feed or eject. I have recently traded my 9 mm and have since acquired a Glock 22 40 S&W. Great pistol. I am quite accurate with it, doesn't have much recoil and it feels great in my hand. I am more than happy with it!!! I received a massive amount of brass from another member and want to start reloading. I have the dies, brass, primers and have began resizing and prepping brass. My question is what weight bullet to go with?? I have read conflicting articles on using 180 grain projectiles and pressure spikes due to the bullet being longer and sitting in the case a bit deeper. I am not trying to blow my gun or hands up!! I have the same two powders to use, Alliant Power Pistol and Hodgdon HP-38. I am only looking to load for target practice/plinking. Maybe a few hot loads for the impending Zombie Apocalypse I have been looking at 155 grain FMJ bullets. The load data has them moving at about 1100 FPS with the HP-38 and 1200 FPS with the Power Pistol. This data is from the websites of both powder companies. I am just curious as to what others have gone with, the reliability of feeding and ejecting and the accuracy of bullets used. Thanks in advance !!
