HSM/Hunting Shack Rifle Ammunition Features The HSM/Hunting Shack Rifle Ammunition in .204 Ruger is built around a 32 grain BlitzKing bullet designed for rapid fragmentation on impact making it a strong choice for varmint and predator hunting where explosive terminal performance matters more than deep penetration. At a muzzle velocity of 4045 fps the load produces a flat trajectory that helps shooters hold on target at extended ranges without excessive compensation. Muzzle energy of 1163 ft lbs backs up that velocity with enough punch to anchor coyotes prairie dogs and similar game cleanly. The BlitzKing s polymer tip initiates expansion consistently reducing the chance of pass-throughs that leave game unaccounted for. Brass casings give handloaders the option to reload once the brass has been fired stretching the value of each box for shooters who shoot high volumes at varmint colonies. HSM builds its ammunition with consistent powder charges and seating depths which helps this load group tightly from a .204 Ruger rifle. The combination of flat trajectory and violent expansion makes it well suited to open-country predator calling where shots can stretch out. For hunters chasing small fast-moving targets at range this HSM BlitzKing load is a dependable choice.
