Is this the cartridge that seems to be taking the long range, 600 to 1,000 yard, NRA matches? Used in an AR10t?
I've considered getting a second upper and having one of the accuracy guru/gunsmiths make one for me.

I think Tubbs is using his called a 6x just a 22-250 case changed and using 1/8 twist barrel for the lvd 6mm bullets. Think they found out that case is better than the 243 and won't burn barrels as bad. I would of gone with the 6x but didn't want to form cases but have heard someone is making cases for the 6x now.

I think you'll find the the 'X' has it's shoulder moved back. It isn't a straight neck up of the 22/250 anyway.

Just not sure need to pull up Tubbs web page and look.
