I finally made time to test my first loads using the pulled Speer GDHP bullets. These bullets are pulled so I didn't expect super accuracy, but was hoping for reasonably good accuracy. The standard COL for these bullets in 9mm is 1.120", but I decided to load them to 1.100" to closer resemble some of my other tested loads. I started with PowerPistol, since it is a powder I like in 9mm, and I normally see two different accurate loads for a specific bullet, at around 5.3gr and 5.6gr. I think these pulled bullets performed very well, and was consistently accurate towards the higher charges. I will probably go a bit higher with the charge just to see if there is any drop-off in the accuracy. Following are the results from the testing:

The next powder I will work up some loads with will be BE-86. With BE-86 I normally try to get to SD velocities since BE-86 is well suited for it due to the flash suppressant. My target loads will be from 5.2gr to 5.7gr initially, and then I will reevaluate to see if I want to go higher. From the testing data I have seen with GDHP is that 9mm comes in at 1150fps and 9mm+p at 1220fps from a 4" barrel.
