Question for the reloading experts out there...what is causing my cases to split like this? Details of load: Both are 9mm, the one on the left is WWB and the one on the right is Federal (the cheap Walmart stuff). Montana Gold 115 grain hollow point. Accurate #5 @ 6.2 grains OAL is at 1.1300" I'm pretty anal about my brass, and sort it by number of times fired. This is what two out of a batch of about 500 looked like after being loaded and fired 4 times (included the factory loading). 6.2 grains is within the loading limits provided by Accurate Powder (loading data here: http://www.accuratepowder.com/wp-content/uploads/2011/01/accurate_load_data_3.5.pdf). The recoil feels slightly softer than the factory ammo (again WWB and Federal). Also, I tried using slightly less powder at one point (at 5.9 grains), and it would not function in my well used G19. I was under the impression brass was supposed to last for many reloads (10 times?). I believe my loads are pretty soft, but it looks like it is too much pressure for the brass? Any help would be appreciated. Thanks. Wanna kill these ads? We can help!
