Is there any "secret" to getting a consistent seating depth?
Out of 5 rounds loaded, the COL ranges from 1.2558" to 1.2443". If I run the rounds through the seating die again (nothing else on the shellplate), they all are seated a bit deeper, but the range is still about the same.
The shellplate is reasonably tight and I see no movement while loading and my thumb can not push the plate down any more.
When I do a "thumb test", the rounds do not get any smaller, so there is no bullet set-back and even cycling some dummies through my gun produces no measurable set-back.
Thanks.

The variation you are seeing is due to variations in the ogive of the bullet. It helps if you tighten the die lock rings with a fired case up in the size die, and seating a bullet in the case, this helps.

Thanks. I always set the seating depth and lock the ring with a bullet being seating in the die, but I never also had a case in the sizing die.
I also find that the handle with a full shellplate will "bounce" back up and inch or so. I have checked with one case going around and there is no "bounce back," but a shell plate full up to the powder measure/powder funnel with start having this bounce back. I don't see an problem with it, but then I don't remember the press doing this, say, 6 months ago.

Case length is ABSOLUTLTY CRITICAL, trim cases, note rim thickness also plays a part. KM
