Texas Triumph: 3600-Yard Shot with .375 CheyTac
They say ??things are bigger in Texas??. Well shots are longer too. In this video, a shooter successfully hits a 1-MOA target at 3600 yards with a .375 CheyTac rifle. That required plenty of elevation to compensate for the bullet?_s drop over its 2.045 mile trajectory. The shooter, Jim Spinella of New Jersey, needed a whopping 60.2 Mils of elevation (26.8 in rail, 22.6 in turret, 10.8 hold-over). Jim had to wait a long time to confirm the hit ?? with the metal gong situated more than than 2 miles from the firing line, it took the bullet 7.2 seconds to hit the target.
Big 350gr Bullets with a Wicked BC
The 3600-yard hit was made with CheyTac factory ammo using 350gr CNC-turned bullets. Spinella was impressed: ??The ammo chronographed out at 3080 fps with velocity differences at no more the 7 fps, which was outstanding. We found the true BC over 3600 yards to average 0.810 (G1)??.
This ultra-long-range adventure took place last September at the FTW Ranch in Texas. Spinella worked with a team of experts from Hill Country Rifles, builders of the custom .375 CheyTac rifle, to achieve a 3600-yard shot on a 36?? round steel target. Hitting a target at 2.045 miles is no mean feat. That 36?? gong represents slightly less than 1 MOA at that range. A lot can happen to send a bullet off target during a 7.2 second flight.

CheyTac Caliber Comparison ?? .375 vs. .408
The shooter, Jim Spinella, prefers the .375 CheyTac to its .408-caliber Big Brother: ??I shoot both the .408 and .375. Both are great ELR rounds and will get you out there a long way. In my experience, the .375 will get you out there a little bit further. My preference is the .375 Cheytac over the .408. This has nothing really to do with external ballistics. It has to do with fouling. My .408 will go from stellar accuracy to terrible between 40 and 45 rounds. It happens that quickly and accuracy returns after cleaning the barrel. I have never experienced this with the .375. After 100 rounds there is minimal copper fouling with the .375, but I clean around this round count. I don?_t know why there is heavy cooper fouling in the .408, but it is common to this round and other shooters who shoot it regularly. That said, I lightly clean the .408 using Wipeout and go back to having fun with it after about 30 minutes.??

If you go to the Youtube video comments, he said he made dozens of 2 MOA shots around the target before they got close.
Probably 25-30.

I had to go look for that, interesting comment:
Thank you! We peppered the 2 MOA area around the target with a couple of dozen rounds. We hit the rack the target is hanging on twice. This was a fun experience, and we took a lot of data away from it. We put a lot of work & planning into this in order to be in position to be lucky. So many things are ridiculously magnified at that distance. Every 1mph in wind is about 6 ft. 10fps in velocity differences shot to shot are almost 5 ft so as the barrel heats up the velocity changes with it. Great friend, and lots of fun doing it. Thanks for watching.#65279;
