Do you have a T/C barrel chambered for the 7x30 Waters?The 6.5 Creedmoor, I'm thinking of either getting another one in another caliber or rebarrel/rechamber this one. Shooting factory Winchester 125 gr. ammo I'm getting 1.2" groups at 200 yds. with this pistol. I'm going to sell some T/C stuff at some point to help fund the addiction.
Oddly enough the Nosler doesn't like Nosler ammo.
It also likes the Barnes 127 LRX but shoots the Winchester a little tighter, avg. velocity right at 2600 fps. I figure it will work fine on an Antelope.
