Last October we told you about Steve Spinella, of New Jersey, and his record-breaking long-distance rifle shot of 3,800 yards. But did you know he broke his own record about two months later—by a solid margin?
According to this story from Texas Fish & Game, on November 22, 2015, Spinella hit a 36" plate at 4,210 yards with an HCR 375 CheyTac rifle—a distance of 2.4 miles. Each of Spinella's three record shots (the first was 3,600 yards) required Hill Country Rifles in Texas to build a unique rifle, though each were chambered in 375 CheyTac.
The story says one of the most drastic improvisations was engineering custom mounts to avoid running out of scope adjustment. A 230-minute of angle rail was machined for a 20 MOA Nightforce Unimount for a total of 250 MOA.
The scope the team used was a Nightforce Beast that allows for an additional 34.9 MILS of come-up.
“The last 400 yards adds 1.5 seconds to time of flight and the bullet drops and additional 265 feet. That is a lot of time for the wind to push the bullet. Another major obstacle to this shot was that the equipment would only calculate ballistics to 4,000 yards. So just finding a starting point in terms of dope was a challenge.”
