6.5 prc prefit reamer question

[badseed]

Im building a 6.5 prc and am considering buying a pre-fit barrel. Ive read multiple discussions about tight chambers and clickers when using samii spec reamers. What I don't know if this is still a problem with pre-fits? Do you have to get a smith to use a custom reamer to prevent these issues? If it makes any difference I am looking at Proof CF barrel.

Check with the prefit manuf to see what reamer they use.
Alex Wheeler has a modified one (AW2) that opens up the base of the chamber a couple of thousandths to mitigate the potential issue.

I contacted Preferred Barrels about the PRC reamer they use and they did mention they use a reamer that corrects the clicker issue.

That would be great if all barrel manufacturers adopted the larger reamer for the prc but it is odd that you have to deviate from saami spec to make the chamber work with reloads.

In case anybody else is wondering which reamer Proof uses, they use a standard saami spec reamer for the 6.5 prc.
