What are you using for powder with the 255 grain?
Are you using a heavier recoil spring?
They look mean!

I hit the range late this afternoon to chrono/test some 9mm rounds. 3 gr, and 2.8 gr of N320 under a 150 gr blue bullet. The 3 gr loads were making ~127 PF, while the 2.8 were about 124 PF. All cycled fine with the 10# spring in my DW PM9. Thigh the 2.8 gr loads were fairly dirty since these are pretty light loads. Fine for steel plate matches though.
Then I wanted to make loads that meet 125 PF for IDPA/USPSA. My previous loads that I had been using were with 3.3 gr but those were getting me 135 PF when I chronoed those a couple weeks ago (40 degree weather) which is more than what I need. Looks like 3 gr will do just fine.
One of the guys I shoot steel plate matches with on Wednesday nights, uses 2.4 gr of AutoComp under a 150 gr blue bullet. I think he said it's like 115 PF but cycles his Glock with a lighter spring. He's blazing fast with steel. He just made Master class in USPSA recently.
Got everything I need to begin reloading .50AE. Also built a platform on my work bench that allows me to quickly switch between my two Dillon 550B presses. Generally I have one setup for pistol, typically 9mm, and one setup for rifle, mostly .223.
Used some T-Track and T-Slot bolts secured by hand tightened wing nuts. Works like a champ. Saves space by only having one device secured to the bench at a time.
Nice, pics?
I like it. I keep mine on a double (glued & screwed) chunk of 3/4" plywood that gets bolted to my bench. The plan is to add a second machine rather than screw around with swapping primer assemblies for 6.5 Creedmoore.
Yeah, I have a second machine and this makes it easy to swap. And I have a tool head for each reloading caliber.
Generally I'm reloading 9mm and .223 and just swap machines rather than calibers. But as you can see I have .357 mag on there now. At the moment I reload .380, 9mm, .38, .357 mag, .44 mag, .45, .223 and .308. Adding .50AE soon as I just got the dies. Any other caliber I use I buy.
Perhaps I missed something. One of the few PITA I had with a 550 was adjusting the primer feed when switching from one primer size to the other. Had I two,
one would be for small primers and the other for large. Then again, I'm getting on and perhaps I don't remember too clearly.
I think there are two camps: One that swaps the primer assembly and one that swaps the entire machine.
I'm not sure which is easier from and accuracy and time saving perspective but swapping just the primer assembly would be cheaper.
I loaded some 9mm in both Blue Bullets and Acme HiTek. Pretty crazy the difference in diameter between the two. I usually load plated and that's what my dies were setup for. I had to really open up the case mouth for the HiTek and almost back it all the way out for the blue bullets.
