FIRST CHOICE for defense against heavy grizzly
Our 540-gr +P Hammerhead Ammo is the ideal choice for stopping heavy bears at close quarters or hunting them at short range. This Hammerhead bullet has a meplat (frontal flat) diameter of .360”, which is just one tenth of an inch less than bore diameter. With its tremendous weight to diameter ratio (sectional density) it provides end to end penetration on the heaviest of bears, with exit, and does tremendous damage per unit of penetration due to its extremely blunt front end. This load is carried exclusively by NOAA for protection against coastal grizzly attack. It is also carried by the National Marine Fisheries Service and the U.S. Geological Survey for protection from grizzly attack. For the specific task of stopping a grizzly charge, this ammo has no peer.
Modern 1886 pattern rifles can use this ammo if they will easily chamber. The throat dimensions will determine this. Example; the Pedersoli examples tested have chambered this round fine. Browning and more recent Winchester’s pattern 1886’s generally will not chamber this round. In many cases being so close you can relieve the interference by twisting the nose of the bullet in sandpaper where the rifling starts to engrave. Additionally on Ruger No.1’s; Ruger has used different throating dimensions thru-out the years, some will chamber and some will not.
