Re: FN Mauser build
Mauser34,
Treebasher brings up a point that reminds me of something I forgot to mention, I had forgotten to mention. The 6.5x47 (wearing my asbestos pants right now), while a great round, has reported problems with some firing pins/holes being too large for the SRP'ed case. This is with warm to hot loads, and based on what I have heard (I have no actual hands on experience). Either way, it might factor into your caliber choice, as it may cause more work needed than just screwing a tube on the action (so to speak).
