How much round to round variation do you get from your reloads?
I measure mine from the ogive so there is no variation. However, if you're measuring from the tip of the bullet you're gonna see some variation. If you're using a magazine you may have an issue if you are loading to mag length--- otherwise the ogive (where the bullet contacts the lands) gives you a better consistency.
My 9mm rounds vary by .006"-.007" measuring to the tip. I am going to try the single stage tomorrow and compare.
I think plate flexing on the progressive is the problem.
It all depends on the bullet and your dies.
I have found the Amax series really helps on COL. The HP type are quite ahhh flexible in their tips.
The RCBS comp dies are sweet but I load very consistent ammo on regular Lee dies.
Oh heavy or thick necked brass cases, along with those that are a bit work hardened, can throw the seating depth around a bit. For thicker necks a slight campher inside the case neck helps. Blackhills and Winchester brass loads pretty slick even after a few times.
Good luck

I loaded some .308 rounds yesterday and had them all with in +/- .002
I measure to the ogive also on rifle. I have noticed very slight differences on pistol but nothing I worry about.
I tried to load some Gold Dots and the nose was deforming pretty bad. I had to get some new stems from RCBS just for them, according to weight.
I suspected the WW JHP bullets I am loading now, I could not see any deformation.
What kind of progressive press are you using?
