Description
Double Tap's Hardcast Solid is engineered for serious big game hunters who demand deep, reliable penetration from their 45-70. This load pairs a 405-grain wide flat nose hardcast bullet with carefully selected components to deliver consistent performance in the field. From a 22-inch test barrel, you're looking at 1810 fps and 2914 foot-pounds of energy, which is substantial performance for a round that stays safe in modern 45-70 actions.
What makes this load interesting is how it achieves its ballistics. Running at 25,000 psi, it delivers performance you'd typically expect from much higher pressure cartridges. The hardcast bullet construction is the key here, resisting deformation and maintaining penetration through heavy bone, hide, and soft tissue without breaking apart. That flat nose design cuts a clean hole and works well for the ranges where the 45-70 truly shines.
Double Tap's Quality Control and Brass
Double Tap loads all their ammunition by hand using top-tier components. The brass cases are new and reloadable, so if you're into handloading, these spent cases have value. The powder charge tolerance is held to incredibly tight specifications. That kind of attention to detail means each shot behaves predictably, which matters when you're counting on consistent performance in rough conditions.
Perfect for Modern 45-70 Rifles
This load is rated safe for modern 45-70 firearms like Marlin and Ruger actions. It's not suitable for older trap-door style rifles, but that's the trade-off for getting real power from the cartridge. The 405-grain bullet weight is a traditional 45-70 specification, considered adequate for any North American big game within the cartridge's practical range, including larger bears. That heritage load weight combined with modern hardcast construction gives you the best of both worlds.
