2A SNBI
So GA Precision came out with a new 6mm cartridge last year and they named it the 6mm GT, and the guys in the PRS community quickly named it Gay Tiger. It's designed to shoot 105-115g bullets at or near 3000fps, and have better feeding from standard short action magazines than something like 6 Dasher, and have better barrel life than .243 or 6mm Creedmoor. My 24" target crowned 6.5mm Creedmoor was a serious tack driver, but without a threaded barrel I couldn't use a brake on it which meant it was hard to keep the reticle on target in fast strings of fire, so when it finally was shot out at 2800 rounds I elected to go with the Gay Tiger, in a 25" barrel with a big-ass four port brake, and in a heavier contour. Now it's rock solid, and recoil is near non-existent and it's a fucking laser. Worked up a load with RL16 and 109g Berger Hybrids, and it runs 2929fps with a SD of 4.2 and ES of 12.
After getting my load consistent, I loaded up some rounds with increasing seating depths to see how much jump would be best. This target was at 200yds, so all groups are well under MOA, and some are less than 1/2 MOA. I thought it was interesting that 4 of the 5 seating depths showed significant vertical stringing and one did show hardly any...obviously that's the one I'll be using.
KRG Whiskey 3 Chassis, Atlas bipod, Badger 2008 action, Benchmark MTU 1:7.5" twist barrel, Vortex Razor Gen II, 4.5-27x EBR 2C reticle. It's a fucking laser and I can highly recommend this cartridge for competition and even hunting.
