I have never purchased any ammo that is +P. Anything to consider or be aware of? Does it work in all or most handguns?
check your gun
user manualmy AR15 can shoot both .223 and 5.56
some AR15 can only shoot one or other... it all depend...
read your
user manualif you don't have it
check the barrel and guns for what caliber it will take and just stick to that...
you don't want your barrel exploding
