If you planning to build locally, may I suggest?
That one on the far right has a most = unrestricted airpath. I have only a .22 and .25, but pretty much you can calculate from the picture. Now for a .30 cal you better use a CAD because of a wall thicknesses.

I R&D the one on the right 7 years ago, the walk thickness affect the strength of the brass, after shooting high power the brass started to bend i see no benefit in increasing the foot pound energy. One time I made the wall thickness too thin I kinda blew the barrel out the front.
