6ppc reamer

[DShortt]

Thinking about diving into 6ppc. No experience with this cartridge. Any reamer spec recommendations? Just off-shelf. Don't know enough about it to be hung-up on any specifics. Don't mind turning necks to even them out, but not necessarily undersized.

Thanks for looking.

There are multitudes upon multitudes of reamer prints out there with subtle differences. I have tried several,, only to come back to my .269 neck, .050 Freebore.
Another important number is do not go too tight at the web. A number of years ago, shooters got excited about a grind that was .439 at the .200 line. Many complained about getting that click at the top of extraction.
The base was too tight. .440 to .4405 at that point seemed about right. This is one case where a little more clearance is a good thing.

Here's a very recent thread with lots of good info.

I’m looking to buy a new reamer 6ppc with .268nk, what other changes would you all make to this reamer? I’m planning on shooting 65-68gr Bt on .790 or .825 jacket. Thanks
