[QUOTE="Gamesniper19, post: 1954278, member: 95013"] Update: Official caliber name is the 7mm GARRETT. It is complete. After testing and working through the calibration of the free bore and powder cocktails, we feel like we have the caliber in a great place. What we accomplished: [LIST=1] [*]Calibrated freebore and landed at .240. That freebore is optimized for the 175 eldx and will not run the 195 berger; it wont fit in the BDL style mag. [*]By adding freebore we eliminated the pressure spike at 81 grains. We also dropped our FPS slightly and landed at 3210 fps with 81.0 grains of RL25. Very happy with that node. [*]Seeing consistent sub 1/2 groups with best group at .29 running jump .012 off the lands - will probably leave it right there. This is 100% a hunting rifle [/LIST] In my opinion this rifle is equal to or perhaps even better than the 28 Nosler. It runs just as fast, has better case dimensions and powder efficiency and is plenty fast enough for ANY application. I wonder why Hornady marketing hasn't gone down this road yet but no matter, we did and we LOVE IT!! [/QUOTE]
