When it comes to choosing a handgun and ammo, there are no easy solutions. The accuracy with which you fire is significantly more crucial than the weapon, cartridge, and bullet you use. Alaska is home to several very big game animals, including mature bull moose weighing 1600 pounds and coastal brown bears at 1500 pounds. A moose or brown bear shot in the gut with a high calibre magnum rifle, such as the popular 17 hmr ammo, is injured but just as likely to survive as if shot with a small calibre rifle as the.243 Winchester. When it comes to accurate bullet placement in the crucial cardiac area, barrel size, cartridge weight, and velocity are minor considerations.
