Mr. Phillips,

Many thanks for the information and pictures. The profile photo is especially nice as it gives a good idea of the cartridge's shape and size. In exploring Huntington's website a little further, I discovered that Horneber offers brass as well. It's actually slightly more expensive than the Gehmann brass. Anyway, it appears as though the 7x66 should fit into a standard, 30.06-size action although the bolt face would probably need to be extruded a small amount to provide proper case-head support. You may lose one round capacity-wise due to its rather large diameter.

As far as loads go, I'd love to see how the 7mm Barnes TSX and Banded Solids (both in 140-gr.) set up over VihtaVuori N160 or N165 would perform.
