In a semi related thread some posters claimed the Dillon 650 does not make consistently sized ammunition. Has anyone else found this to be an issue and how much variance are we talking and how much of a problem is it?

Sounds like it's not mounted properly.
Gotta be rock-solid

Do you mean it doesn't seat it the same?
Or size it the same?

I have a 550 and it sizes and seats them consistently within specs

I've loaded 20,000+ rounds on mine with no such issues.

If your talking about rifle ammo I've found that the amount of lube matters as well as different lots of brass make a difference. This is using my 550b though. Might get more responses In the reloading forum though.

It's a progressive, not what you want to use to make precision ammo. It's a problem when you have a chamber that that doesn't accept the ammo you're making. There are solutions with dies and aftermarket parts, for example the Lee and EGW U dies, and Lee factory crimp die. Redding also makes sizing dies that go almost all the way down. I wouldn't even worry about it unless I had a problem chamber, but getting the shell plate bearing and low mass detent ball does make the machine run smoother. If you need extremely consistent ammo, there are aftermarket toolheads that attach with clamps instead of the locator pins that dillon uses.

You can load precision rounds with the 550 no problem . I remove the powder tube and  just measure my powder loads each time when I load .308


Its a very versatile machine .

I have found the Dillon 650 to be very consistent when properly adjusted.  The powder thrower adjustment seems much more accurate than my RCBS powder thrower.  Having said that I tend to   run the brass in a brass polisher, deprime and resize on a RCBS Rockchucker trim cases on an electric Lyman trimmer chamfer inside and out and clean primer pocket then hand prime with an RCBS tool.  At that point I load them into the Dillon 650 let it add the powder and seat and crimp the bullet.  I prefer the primer pocket to be clean.  Often I do rifle cartirdges completely on the single stage RCBS because I want the powder charge exact.  Most of the time consuming part of reloading is case prep.  If a guy was making target ammo and didnt care about cleaning the primer pocket pistol ammo would easily be loaded only on the Dillon 650.  I would be a bit more  hesitant with rifle ammo but it can be done on it.  If a guy was loading for a semi auto rifle and needed to make larger quantities of ammo and was able to afford new Lapua brass a Dillon 650 would crank out a lot pretty rapidly but with slight variance in powder charge not enough to be a problem so long as you stay away from maximum powder charge but if you load them HOT you best be exact and if you want true accuracy from rifles you best be exact on your powder charge and seating depth.  With pistols at the distances involved plus or minus a couple thenths of a grain is not going to significantly effect accuracy result, but stretch a rifle out several hundred yards and a few tenths of a grain can be a big difference.  I'm very happy with the Dillon 650 but if you only load rifle a single stage press running the Horniday lock and load die holders might be worth a look cause you can add them to a RCBS RockChucker then you dont have to adjut the die each time.  With a Dillon you buy multiple plates and set your dies once then switch out the plate with the dies and the shell holder etc for each caliber change.

Just like a 1911, he's limp-wristing it.
