Sunday GunDay: Innovative 7mm-6.5×47 Wildcat by Jason Baney

By Editor

Jason Baney was one of the “founding fathers” of this website when we started out as 6mmBR.com 18 years ago. A few seasons back, Jason created an interesting wildcat, a mid-sized 7mm cartridge based on the 6.5×47 Lapua case. In this report, Jason (who now works at Eurooptic.com) talks about his 7×47 wildcat and his initial velocity (and feasibility) tests. To determine the 7×47’s velocity potential, Jason did a multi-stage test, cutting a barrel in two-inch increments. This process is illustrated in a video, embedded below.
You may be surprised that the little 7×47 cartridge could drive a 180gr Berger Hybrid at 2770+ FPS with a 32″ barrel and Reloder 17. Max Velocity with H4350 (and 32″ barrel) was roughly 70 FPS slower. With a 24″ barrel length, the 7×47 was still able to propel the 180gr Hybrids over 2600 FPS with H4350. That’s impressive performance for a mid-sized cartridge pushing a very big bullet.

The biggest enemy in long-range shooting is wind. This also happens to be the hardest to gauge and predict. The only way mere mortals can attempt to defeat the wind demons is to shoot a cartridge
