I’ve owned my TAC A1 in 6.5CM, for just over a year. I finally got around to tuning a load for this rifle. In the past year my best groups were hovering around .6-.7 MOA for 5 rounds with factory ammo. The rifle doesn’t like the lighter bullets (under 140gr). Yesterday I took it to the range, with some of my hand loads. Temperature was 92 degrees, 90% humidity, 20 feet above sea level, wind was 5-10mph true cross value. The group of the day was 4 rounds into .17 MOA, shooter induced flyer on the 5th shot opened it up to .75 MOA. The load was 43.6 grains of RL-16 under a 140gr Hornady ELD, once fired Federal Brass, with Federal GM210M primers. I use .004 neck tension with the billet .003” off the lands.
