Gunsmithing 284 GAP finish reamer

[skeetlee]

Anyone here using this reamer? would this be a good choice for a short action magazine feed rifle? im sure its a no turn neck, but i dont see any info on the freebore. I left a message with Kiff and i even called. but they havent gotten back with me. I have a PRS shooter wanting to shoot the 284 out of his short action Bighorn. I would appreciate to know what you might know about this reamer. Thanks Lee

According to this, it is optimized for the 175 grain matchking, loaded to 3.10, which would not be shot action friendly.
