First of all a little background on myself, as I am brand new here (been reading for a bit). I live in Queensland, Australia, have been shooting for a few years now, and recently started varminting (mostly spotlighting roos, foxes wee wabbits and the odd cat), with great success, very rarely is the target still breathing after the first shot. There have been many posts about 223's and many more about pigs, but as far as I could see, none particularly answering this. My hunting rifle is a Tikka T3 in .223, 1 in 12" twist, (Leupold VX-II x6-x18 that i leave at x12 almost permanently) I currently handload my own rounds, and I'm looking at buying a second magazine for a quick switch to a 2nd load on the chance that we see a pig while spotlighting. I realise that .223 isn't really a pigging gun, but it will be a while until I buy another rifle. I am comfortable with my accuracy (load and skill), so shot placement should be easy enough, which brings me to my questions. 1) Bullet Type. My current load is: 50gr Nosler Ballistic Tips (orange tips) 24.5gr AR2206H This gives me 1/4" groups (mickey mouse, clovers, one-holing etc. whatever you wish to call it) at 100yards. Head shots most of the time, except for difficult shots where i go for the Heart/Aorta. Now, I'm not certain on what bullet would be most suited here, but as far as I understand, the Nosler Ballistic will generally break up much too soon to be even the slightest bit effective on pigs. Perhaps something in the 60-65gr range? Solids/Hollow Point/Soft Point? I have seen .22-250 make quick work of pigs with 50gr Nosler Ballistics (neck shots) though admittedly it is travelling at ~3800fps as opposed to my ~3100fps. 2) Shot Placement There are a few areas to aim for, behind the ear, the neck, below the shoulder (to get the heart). I know my 223 wont do much more than anger the pig if I hit his skull or shoulder blade, so any particular recommendations here in reference to bullet type/weight would be very much appreciated!
