[QUOTE="Stix, post: 717060, member: 43033"] G'Day all. I'm trying to make a more informed decision for a hunting rifle and would like to hear peoples thoughts on the penetration power or high velocity vs high energy calibres/projectiles. I primarily hunt large feral pigs in the 100-150kg range at 150-350 metres (soon to be 500m +) and need good penetration to hit running pigs and either smash large bones or leave a decent exit wound. I often shoot 10-15 rounds in 1-2 mins and so can't go much past a .308 recoil wise. Most people will instantly say the larger calibre with heavier projectiles will have better penetration. At some point though a lighter but faster bullet with have more penetration. I have seen 22-250 punch through steel when a .308 wouldn't. I know shooting steel is a lot different to travelling through 2" of mud and then 2 feet of flesh and bone. Obviously bullet selection is critical but i use nothing but controlled expansion bullets with extremely high weight retention (Primarily Accubonds). So at what speed would a 100-140gn pill have equal or better penetration to 180gn .308 at 2600? Basically just looking to see if there is a smaller/faster/flatter calibre than my preferred .308 which will give equal or greater penetration for equal or less recoil? [/QUOTE]
