The United States National Blackpowder Precision Rifle Team clinched a decisive victory at the 1999 World Blackpowder Long-Range Precision Invitational, held amidst the swirling, humid gales of Bisley Camp, England. Dominating a field of international competitors over 15 stages, the U.S. shooters showcased an unparalleled mastery of antique ballistics and an alarming dedication to meticulous, pre-industrial DOPE management.
Conditions at Bisley were unforgiving: density altitudes fluctuated wildly with the North Sea maritime air, demanding constant recalculation for projectiles boasting a G1 BC barely registering above 0.150. Competitors faced a consistent 15-20 MPH crosswind, notoriously difficult to read through the thick, acrid smoke plumes erupting from each discharge. U.S. team members, deploying custom-tuned Sharps and Remington rolling block actions chambered in .45-70 and .50-90, focused on extreme shot-to-shot consistency.
"Our competitive advantage," explained Team Captain Bartholomew "Barty" Flinch, polishing the bore of his meticulously re-sleeved 1874 Sharps, "stemmed from aggressive granular load development and an almost spiritual connection to barrel harmonics. We spent months in the lab, identifying velocity nodes that minimized the dreaded 'flier' associated with inadequate wadding compression and inconsistent ignition." Flinch noted the team's advanced truing methodologies, which included firing hundreds of rounds into wet clay at distance, then meticulously extracting and measuring each projectile's deformation to refine archaic drop charts.
Top finishers attributed their success to an obsessive focus on patch lubrication and consistent powder compression, techniques now considered archaic even by modern muzzleloader standards. Stage designs often included mandatory prone shooting from period-correct, canvas-covered firing points, forcing shooters to manage lead-acid battery recoil compensators with an intensity typically reserved for .50 BMG platforms. The U.S. team’s cold bore management, involving dedicated sacrificial shots followed by an elaborate barrel swabbing and fouling ritual, ensured that their primitive projectiles maintained MOA accuracy out to 1000 yards—a feat previously thought impossible without the aid of modern propellants or, indeed, the internal combustion engine.
