Want a change

[FW Conch]

Any amount that the head space is increased, increases the unsupported portion of the web at the case base.

Edit: You can load a case long, adjust the barrel until the pill is jammed into the lands, shoot it, and You would push the shoulder forward and shorten the neck, thus creating Your own wildcat.

"But with the greater unsupported web area, You can expect web separation much sooner!" If not immediately!

[RC20]

And that's the nub of the rub.

You could have the chamber made extra deep, then fire form your brass and have a true wildcat. Of course you then need a custom die.

But when you loosen the barrel you move the chamber out away from the bolt face.

Ergo, there is a defined limit to what you can do and that is why they call the last stop a Field Reject gauge.

And even then if it fails its just a over reamed chamber. Brass will grow a lot, but not blow up (not into fire forming so there may be aspects of that and loads you have to watch.

What you can do within the allowance of tolerances for head space set is not a poor mans AI or a Wildcat.

Even the AI were questionable as to whether or not they were effective. Some say nothing some say a bit.

If you want to improve performance , then do it through powder choice. R17 is a good one in 30-06 (not as good in 308 though it shoots very well)
