I prefer 180gr Core-Lokt myself, but again the key word is "prefer", it's just my personal fetish on 30-06 bullet weights. And as for the Core-Lokt, well it's cheap, accruate enough and when they connect they are deadly, my hunting friends and I call Core-Lokts "deer bombs" b/c once they met the rib, they friggin explode. One time I shot a doe for vension at about 40 yards with a 180gr deer bomb, it was a gut shot. Anyways after I tracked her down she was bedded 25 yards back into the woods, after I put her down with a head shot, my uncle and I examined the situation. After I shot her, I ran to where I thought she dropped but didn't find her, then I walked into the woods, found about 2 liters of blood and 1 of her 2 intestines in it's entitery on the ground in the pool of blood. The deer literally looked like it had been split down the middle with a buckknife, a perfect lasion running from her tail up to her breastbone straight down the middle, you could see all of her guts. So that is my story of how effective 180gr deer bombs aka Core-Lokts can be on deer, imagine if I woulda put one behind her shoulder!
