Hello again guys. Remember my recent post asking why I'm experiencing problems with 9mm 115 gr. XTPs using Longshot? Today I was searching for answers by every means possible when I discoverd what my problem was. All I can say is that I'm lucky I only have egg on my face and not pieces of the gun. I made a mistake that is going to haunt me for a long time. While my Son and I were shopping for bullets for the new 9er he bought we grabbed a box of 115 gr. Gold Dots and a box of 115 grain XTPs. Undeniably my fault, I grabbed a box of 147 grain XTPs and managed to not notice. I'm getting up there in years, but have been hand loading with great care and rspect for so many years that mistakes like this didn't seem possible. It goes without saying that no matter how much experience we have, it is always necessary to physically read every lable and double check each step of the process. I'm ashamed of myself because I'm so adament about paying attention to detail, yet I managed to make this potential deadly mistake. Maximum powder charge for the 147 grain XTP using Longshot is 4.7 grains, I loaded 5.8, well over a 20% error, and was complaining that I was only getting 1050 fps. This bullet weight has a maximum velocity of 1003 fps with any of the powders on Hogdon's listed data. Suprisingly this 5.8 grain load didn't go KB, but sure did exibit some maximum pressures just short of complete case separation.
So thanks to all that offered their help in my original post, but the problem was all pilot error, usually is.
