My advice to anyone on here who believes this is a problem talk to your smithh about what reamer he is using and especially you guys who do pre-fits.
That should be the #1 question you should be asking is about the reamer being used on any pre-fit or build not only on the PRC's but even if the proper freebore for bullet and Neck clearance for brass you wanna use.
Charlie we are gonna agree to disagree, everbody good luck on your future builds
You are disagreeing with the wrong person. Charlie is not only an excellent gun builder, he also has pressure testing equipment and is proficient in its use.
