the .22 cal has a smaller transfer port. the 30 cals have a bigger transfer port. i have not opened mine up yet to see the TP diameter in the breech. but having a bigger TP in the 30 cal barrel will also help.
I don't know much, but I'm wondering if you considered the JSA Raptor? The RTI Priest 2 seems along the same lines as the Raptor, being tactical-looking, bottle-fed, very accurate, very powerful, etc., and the same price. I don't have a clue how easy the Raptor is to work on, and it is very new. Edit: Oops; now I see the date of the original post was June 2019, before the Raptor was even available.

Atom, what did you do to get that big damage in that valve housing area? the trigger is not the only difference. the magazine was redesigned, also other things.Atom, what is the ID and length of the plenum? Mike, i considered the raptor vs the crown. i went with the crown cause i had fx slug liners ready to go. besides, i didnt want to wait for the preorder. Frank, i am well pleased with RTI customer service. Harold, the port on the 30 cal barrel will help. if the ports in the breech were bigger that will also help with fpe. try opening your barrel port to 3/16 and see if that gains you the speed you need
