I finally ordered my Dillon Precision 550 press with all the accesories I need to get started. Even bought a chronograph a Competition Electronics and a starter bench from Stack-On, the 382. Anyone that knows me on here knows my passion for Carver Custom raceguns and shooting with the dot and comp., finally I can start building loads to suit those guns. Before it's even said I realize some of you told me to go with the 650, but my sponsor Bobby Carver as well as Dillon Precision and Brian Enos and even some of you told me to go with the 550, so I did. Now its time to gather some data, here's what I am thinking of starting with. For the 40S&W limited I am thinking of starting with a 180gr bullet, for the open (compensated) a 155 or 135. For my 9mm open gun, 124gr and for the production (GSSF) load I am thinking 147gr. Figured I would start with Federal primers and Winchester Auto-Comp powder. I have about 5000 cases, once fired, to start with so I am good in that respect. I am planning on getting all of my bullets from Montana Gold and X-treme. So those are the bullets weights I know I need to be running. My question here is are there better powders to run in these guns with these bullet weights and if so what are they and why???? Keep in mind the 40 open and limited must make major power factor (IPSC) and the open 9 minor IPSC PF. Thanks. Wanna kill these ads? We can help!
