I have become concerned with my methods and equipment. I have been using a Dillon 550 for all of my reloading career (15 years). It was used when I got it back in '95, and I have pulled the handle 392kajillion times :lol: Last winter I rebuilt the press, and Dillon furnished all the parts and updates.... didn't cost me a dime!!!! Dillon always has been an upstanding company!!!

Back on track.....
My concern is seating bullets on this progressive press. Would it cause excessive runout? It definetly seats bullets very consistently as far as OAL is concerned. The case can more or less "float" and line itself up with the die. The die head does have some movement, but everything seems to work well together and produces very consistent ammunition. I do not have a runout guage, I'll admit to rolling the cartridge on a flat table trying to see the tip of the bullet wobble.... everything looks perfect to my eyes. :shock: Honestly, I feel that the quality of the die itself is more important than the press.... But do you guys think my groups would shrink if I bought a single stage press?
 
NO. RCBS had a reloading video using David Tubb as the instructer. During the video, he used a Dillon 550B and checked the runout. I think he was surprised how good they came out of the die. I quit checking the 223, 22/250 and 308 that I loaded. A friend of mine loads his 308 and 30/06 on a Dillon. He shoots at Perry every year.Rick.
 
thanks rick, I had a bit of a confidence booster this afternoon with my loads!
 
How much does concentricity matter? I'm still using a single stage RCBS press, I saw in the Natchez catalog they have a concentricity tool. I get how you can measure the run out, but this tool say's it will fix it or zero it out. Any thoughts on is it worth having a tool to do this?

For competition... a lot but for hunting, Zzzip!

I love my progressive machine for pistol and revolver reloading but, I won't use it on any of my rifle reloading.
 
Chet -

I have been wondering the same thing as I'm currently using a Dillon 550.
I gave the old Rock Chucker back to my Dad that we have used since I can remember.
I don't load any pistol cases or high volume rounds to justify it, but can't say I saw my groups open up after switching to this one.

One thing I can say - CAUTION - If you switch dies back and forth in the Dillon tool head, be SURE to check COAL - I've found the tool heads to be machined slightly different, thus causing the COAL difference.
