I am using the VLD, further drilled to make room for the long bullet. The seating stem is doing its job fine. The die is maxing out, which I have to look into.
Will ask Redding and Warner.
Seating bullets by chambering?

I said the same thing in an earlier post

Yes, don't understand the issue.
If'n you're going to use chambering at seating, as long as your neck tension is light enough or nonexistent, and your leade is configured to assist with alignment.
If I read correctly, you have 1.5 mil runout, which is not unacceptable.
The bullet and case being "too long" for seating is ridiculous. Aside from having to drill out seater stems to accommodate long points like with the Berger OTM tips, just back the die out.
For example, before I received my dies from Gunwerks, I used a 7 SAUM to seat 180's in my 7mm LRM cartridges.
Back the die way out, back the sliding seater stem out, measure, lock, and go. No measurable runout.

Regarding putting a locking collet on the ram below the bearing, not a good idea. As as your arm extends down, because it's a camming action, the force on the ram increases *significantly*. Unless you have clamped the locking collar to the point of stretching the collar locking bolts, you'll just move it on the ram, possibly gouging the surface. That would be an "oops".Have you tried using a split shaft collar installed on the ram below the press to limit its upward travel? Once limited, fine length adjustments can be achieved via the die micrometer.

Are you trying to seat the bullet in the chamber with powder in the case or empty?
If there is powder in the case laying on its side, it can act like a ramp against the boat tail of the bullet and push it sideways. Depends on load density and powder type how much leverage it will create. Trying without powder might solve the question.
As for die settings, sounds like you want to be able to switch between bullets and only change the micrometer setting.
That may or may not be possible. Set the die up for the longest bullet and hope there is enough adjustment for the shortest bullet.

OK, I took ten minutes and gave it a good look. He’s dealing with a REALLY long bullet! It’s 1.8 inches, about. I pulled out my Redding 338 Win Mag die, screwed it in 3 threads and looked at. It ain’t tall enough to seat that bullet! He needs to whack some off his seater stem!

Unexpected resistance during any part of the press handle stroke is a clear indication that something is wrong and to stop, especially when seating bullets, at least that’s the way I load...
Totally agree. I move my handle slowly when both sizing and seating. Near the end of the stroke, I've crushed a shoulder on the case (ripple the shoulder/body junction) without even feeling it. All it takes is 2 mils of travel.
I laugh, thinking back to when I started reloading, trying to see how many rounds I could produce in an hour. Broke a lot of primer pins.

Dear me - Its the bullet that's too long, not the case! So the die is correctly screwed in the press to accomodate the case. The issue is the die length from the case shoulder to the seating plug. Breech seating - not for me, I prefer more neck tension and of course, you will always be jamming the projectile. Time to give up on a std Redding and look elsewhere. As you have the die, I'm sure that a new die body could be made by any competent engineer and the internal components reused. All the dimensions are there on the Redding plus increasing the "height" by whatever you need to accomodate the bullet, the only "extra" would be the spring (maybe just add another or a spacer?).

Yes - soft seating can stick a bullet if having to unload during a cease-fire, though if moly or HBN coated bullets are used, it is used - it is very difficult to stick a bullet. While one can argue the merits of moly all day long in many respects- it does prevent bullets from sticking in such "low neck tension" soft seating situations - and I have used this method for years. This method also eliminates "chasing the lands", as every round is centered in the bore in the same position upon firing. Eventually - the overall longer length creates dynamic changes to the load due to internal powder capacity/air gap, etc., though they are easier to overcome with a minor powder tweak than constantly keeping the lands at the same proximity to the bearing surface of the bullet. At least that is my take on it. I do know that it works wonders in a few of my barrels.
Thankyou for putting in the effort and realizing my problem. I almost felt like a fool for not being able to explain my situation better. Will look into other options for seating these. Thanks again.
I suggest calling Alan Warner to discuss this problem. After a short conversation with him you'll understand how to solve this:
