6x47 Lapua reamer help

[jwcrabb]

Guys,
I am ordering a barrel from PacNor in 6x47 Lapua. I sent a email to PacNor asking if they could do a "no turn" neck and throated for bullets from 60-90g. They sent me back a reamer spec. with a throat of .5237. I am new to this so i'm wondering if this spec will fit my needs? Thanks

Looks like a no turn with .093 free bore. It should work good with the 90s but I would say its a bit long for a 60 grain but it will work they will just be hanging out of the case a ways. Overall it appears to be a pretty versatile chamber.

.274 nk should be no turn. For a 60gr bullet, if you ever wanted to touch the lands I would probably be a .030-.040 freebore. I can't imagine you'll come close to touching with a .093.

Thanks for the replies. I should have added that this is purely a hunting setup. The idea is to run the 58-65 VMAX for Coyotes(90% time), with the ability to use the 90g Noslers for Deer if necessary. Max range would be 400yds with most shots 0-200yds. Is it important to get into the lands with these lighter bullets?

If your going to run the 60gn 90% of the time you may want to shorten up your freebore. I have a .060'' and it works well with the 60, I have a good .125 of shank in the neck with a .010 jam. If you are using a bushing die then you wont have a donut issue as you don't size that part of the neck, it will be ok to have the shank of your heavier bullets down there on your hunting rifle.
