Feed rails too wide ??

[Varmint Hunter]

I have a 7WSM built off a Bordon magnum short action. I'm going to rebarrel the rifle in 6.5 PRC. Will I have an issue with the feed rails being too wide? Has anyone else done a similar conversion?

I wouldn't think so... but, never did one either. Good luck Cheers

My initial thought was that the head diameters would be more disparate.
With a modest .003" difference in head diameter, I'd have to agree that it wouldn't present a problem.

Thanks for the diagrams.

Like reading, math can be critical:

0.555
- 0.532
________
0.023 (this is 23 thousandths not 3 thousandths)

.535 not .555

That's the rim not the head.

The critical dimension in this question is not the case head or rim, it is the body diameter. I have built several rifles with both Nosler/WSM cases and PRC cases with no issue. Worst case you may need to tweak the magazine box assuming this is a BDL style setup.

I stand corrected, thank you for pointing out what matters and why!

Hmmm, very interesting. My original suspicion seems well founded. It's always helpful to get feedback from guys who have "been there and done that".

The action is a BDL style with internal mag and a floor plate.
