Ok, so this past Tuesday my Lee Challenger Breechlock press came in. I'm new to the mysterious craft of reloading, but have learned a couple of things during the past few months with my basic Lee Loader kit.
I just finished loading 275 rounds for my .357 magnum. It has been a bit of a learning experience because I've found that so many details can affect the outcome of the load.
I thought when I mounted the press to my bench that the linkage was free from contacting any part of the table. I was wrong. I had a few problems with getting consistent OAL because the bottom of the handle was striking the framwork of the bench.
Until I realized this was happening, I continued to fool around with the seating die, thinking it was moving slightly on it's own. I struggled with this through the first 150 rounds until I saw the handle hitting the table. Problem solved!
I continued on with a little bit more ease, but I was still having trouble with OAL. I figured I was doing something wrong with the die and figured I'd make a post... until upon further investigation, I realized that the XTP hollow points will actually deform ever so slightly when pressed into the case. The seating die never shifted on it's own, so I think I narrowed down the problem.
The safety prime system that mounts to the press worked flawlessly. I didn't have a single problem out of it that I didn't cause. I was skeptical about it because I think it only had 3.5 star review. It was cheap and available, so I jumped on it. Good system, in my inexperienced opinion.
I don't have the cool Powder Disk Measure that mounts to the press, but I do have the Lee Perfect Powder Measure and I was highly impressed with it's consistency. I think I've made one adjustment to it in the 275 rounds that I've done so far.
The die set that I have is the 3-die carbide system. The only thing I can think of that I could do to make the process more efficient is purchasing a second bullet seating die, specifically so that I can have one die set for bullet seating and one die set for crimping without making adjustments to either. Happy with my purchases.
Just though I'd post my first experience and try to see if my OAL inconsistency theory sounds right to you guys.
