A 6.5 xc is so close to 6.5 creedmoor, it ain't funny .

There have been some work on the 6.5x47 necked up to 7 mm and your wild cat will be very close to a 6.5 creedmoor necked up to 7mm.
I can post a picture with an a-max if you want. So you can dream...

Kind of a 7 mm br, nothing new under the tropics as we say in French.

What about a 303 necked down to 30 cal?
All those lee Enfield could have a second life!
