The prestigious ColdBore Ballistics Institute today announced a monumental breakthrough in rimfire precision, unveiling a meticulously engineered ballistic solution for .22LR engagements out to an unprecedented 3000 yards. This development, spearheaded by Lead Ballistician Dr. Aris T. Otle, promises to fundamentally alter how competitive shooters approach ELR training, and potentially, main match stage design.
Central to this achievement is a highly customized platform featuring a RimX action mated to a Proof Research 1.5” straight taper, 42-inch barrel chambered for Eley Tenex. Optics consist of a Nightforce ATACR 7-35x56 with the Mil-XT reticle, mounted in a Spuhr ISMS mount, providing the necessary 1800+ MOA of elevation adjustment. Researchers meticulously cataloged velocity nodes for over 300 lots of Tenex, identifying a sweet spot at 1080 FPS, crucial for maintaining laminar flow through the transonic region – a region previously deemed insurmountable for such a diminutive projectile at extreme ranges.
The DOPE cards generated for 3000 yards are, unsurprisingly, extensive. Factoring in spin drift, Coriolis effect, and localized density altitude fluctuations to the fourth decimal place, a typical 3000-yard holdover required 1400.3 MILs, accounting for an estimated 275 feet of bullet drop. Wind calls, traditionally daunting for centerfire ELR, become an esoteric art form, with a 1 MPH full-value wind at 1500 yards translating to a 12-foot adjustment. Dr. Otle emphasized that this level of precision demands not just a Kestrel 5700 Elite, but real-time satellite imaging for true atmospheric sampling across the entire bullet flight path. The institute anticipates competitors will begin lobbying for 3000-yard .22LR stages in the upcoming NRL ELR season.
