Shot out the barrel on my 110 FCP .338 Lapua and have decided to make the switch to .338 Edge. I've already ordered the barrel from Pac-Nor as well as some new dies and brass.

I understand that the Edge is based on the .300 RUM (aka 338-300 Ultra), and that is where my question comes in. Will I need to switch to a smaller bolt face given that the case head diameter of the Lapua (.585ish) is larger than that of the RUM (.540ish)? Or will the smaller diameter case work with the larger bolt head and extractor? Are there any other considerations I should be making?

I willl continue to update this thread with my progress, although the rifle is already done for the most part
