AA 14" Barrel?

[65Whelen]

I bought one of the Sabre 14.5" Grendel barrels from RedXArms and a Saturn Heli-Coil Muzzle Brake from a fellow Horde member. The barrel is a little dinged up and the throat is on the short side. I have four different bullets on hand and the 129 SST is the only one I'll be able to load to 2.260. Factory ammo(Hornady 123 SST) sticks in the chamber with the bullet into the lands.

Will be loading up some 129 SST and see how it shoots when the weather breaks. It's been a little chilly around here lately.
