I've taken a strip of aluminum foil and folded it several times then place in shell holder which raises case several thousands and then FL size it'll push shoulder back further.

Use a feeler gauge it's more reliable and much more accurate

Ya I could have but, didn't want to take apart set of gauges and loose one. The aluminum works in a pinch especially in a testing situation. But, you are correct about accuracy.

either the Redding full length or the Whidden new size 300 PRC, they have adjusted the size.

That will work but RCBS makes an elevated shell holder for the Match dies that will raise it 1/2" and will go inside the die base so you can set it where you need it.
