For me this could get to be a long list, using my 7x57 I have gotten exit holes using the 150 gr. Nosler Ballistic Tip, the 160 gr. Speer Hotcor, the 140 gr. Nosler Partition and the 160 gr. Sierra BTSP. The Ballistic Tip gave the largest exit holes of around 1/1/2 inches. The rest average around an inch. From my 308 the 165 gr. Remington PSPCL, 150 gr. Speer Hotcor, 150 gr. Nosler Solid bases all gave exits of around 3/4 to 1 1/4 inches in diameter. From my 270 using 130 gr. Nosler Solid bases, Hornady and Speer 150 gr. bullets and 150 gr. Nosler Partition golds I got exit holes just like the ones from the 7x57 with the exception of the Partition Golds, these were very small, close to 3/8ths of an inch. In my 30-06 I generally use 180 gr. bullets though I have shot a few hogs with the 165 gr. Rem. PSPCL, I have used the Speer 180 gr. Mag Tips, standard pointed Hotcors, and Sierra Gamekings. Exits generally are from 1 inch to 1 1/2 inches in diameter. My 35 Whelen which is relativly new to me so I have only used two different bullets in it on hogs, the 250 gr. Speer Hotcor, 1 1/2 inch exit and the 200 gr. Hornady Spire point which bave a similar exit wound. The smaller bores like the 6MM Remington I occasionally use give small or non existant exit hole but still dead hogs. Wow I have killed a lot of hogs looking back on it. The existance of an exit hole does not determine if you will get a good blood trail, it's position is more important like if it is a low chest hit. I like to hit them 2-4 inches above the "elbow", in the neck in front of the shoulder or near the ear. I also shoot them in the spine when all I can see of them is their back. Anchoring them for the first shot is very important where I hunt due to the thick thorny brush they like to head for. Often a chest hit pig will run 50 to 100 yards before dropping.
