Does he still make these dies? How much do they cost?they are open on the inside and only hit the base so it doesnt matter how long the case is

I have been having issues with my 308 Lapua brass shot out of a 308 Bisley match Chamber bolt gun. Second firing I have to FL (RCBS) size the brass and bump the shoulders .003-.004 to prevent the bolt click on extraction.
If I bump the shoulder .002 using the FL RCBS 308 the empty brass will chamber but have the dredged bolt click on extraction.
Same thing for the 3rd firing.
I suspect that when the shoulder blows out and the base is expanding and pushed out the rear of the chamber slightly and not springing back so I get the click upon extraction. This is being shot out of a rem700 close with a Bisley match chamber in a Bartlien barrel.
Do I need to run small base dies because the chamber is so tight? but the reamer specs on the bisley shows a base of .470.
PS I'm using a forster co-ax press and have an RCBS press sitting on the side not being used.
Any help is greatly appreciated. I own a 308 RCBS FL sizing die and a 308 Redding body die and Forrester bushing bump die.
I want to keep the should bump to a min of .002 and size the base/body do I don't get that dreaded bolt click on extraction.
Will the ring die work or do I need a small base die to set the headspace back .002 when bumping the shoulder?
Any help is greatly appreciated from the knowledgeable folks here in the forum.
