DoubleTap Handgun Ammunition Features This DoubleTap Ammunition .45 Colt +P load drives a 335 grain hard cast solid bullet to 1250 fps generating 1163 ft lbs of muzzle energy for serious penetration on tough game or in a defensive scenario. The hard cast solid bullet construction resists deformation on impact driving straight through heavy muscle and bone rather than expanding and losing penetration depth. Because this is a +P rated load it operates at pressures above standard .45 Colt ammunition requiring a firearm rated for the increased pressure. DoubleTap specifically notes this load is safe in modern Ruger revolvers the TC Contender Colt Anaconda BFR revolvers and Freedom Arms firearms. This load is also approved for use in modern Model 1892 leverguns as well as Winchester and Marlin 1894 rifles giving lever gun hunters a hard hitting option for deep woods hunting. Shooters should never fire this ammunition in older or weaker framed firearms not rated for +P pressures as DoubleTap stresses these are not standard pressure cartridges. Brass cased construction supports reliable extraction and feeding across the approved platforms. DoubleTap Ammunition .45 Colt +P 335 grain hard cast solid ammunition is sold in 20 round boxes for sale at GrabAGun for hunters and shooters who need maximum penetration from their revolver or levergun.
