That 7 WSSM of Brett Bunyan looks very interesting - must have capacity similar to a 284 to get 2900fps, or is it because it can stand more pressure with the magnum case head.
Alan its a 300WSM shortened 250 thou. 64 gns of water case capacity.

yep I defiantly think the non belted magnum helps a lot with pressures in the same way palma small primer brass does for the 308 size bolt face. worth while wildcat Brett.
I totally understand. I was just putting it forward as a suggestion, and if its the straw that brakes the camels back, then its definitely not an issue.
You are correct about it being a requirement for BR. It is written into the BR rule book, and a match is not official if it doesnt collect all competitors equipment information while running a match. It is time consuming to administer, but people do look out for the information - gun porn is popular stuff.
