[QUOTE="AZShooter, post: 1520177, member: 5219"] As long as we are talking about 6mm made from other cases, here is one that works from a different prospective. No necking down but there will be fireforming. Use a 6 BR reamer cutting deeper to headspace as a 243. You end up with a 6 BR neck which requires turning, a 30 degree shoulder angle and less body taper. Someone beat me to it. It is called the 6mm BRK or the "long 6 BR". It can use the excellent Lapua brass. It was featured on Accurate shooter long ago. Getting 3450 fps with a 95 gr VLD with a 28.5" barrel. Author says says "he can push the 105s faster, but 3220-3240 fps seems to be the sweet spot.” [URL]http://bulletin.accurateshooter.com/2013/10/hot-243-based-wildcats-the-243-br-k-and-6mm-super-x/[/URL] Lately there are many newer cases using a 30 degree shoulder angle. In addition the thinner neck wall requires turning which might lend itself to more precise light neck tension for precision shooting. Around 8 years ago I did the same thing with a 30 BR reamer going deep enough to headspace as a 308 win. It has been fun to use and delivers excellent accuracy. I did it because I had the 30 BR reamer and was too cheap to buy a 308 reamer. Just one more 6mm wildcat to add to the list. If I didn't have a 6mm-284 I would give that 6mm BR-K a try. [/QUOTE]
