Within the last few months, I've had a couple of head-scratchers.
1) 6.5 Creed shooting a 140 grain Ballistic Tip. ~80 yard shot on a WT doe broadside. Central TX, so the doe wasn't exactly big. The near shoulder was turned into pudding, however the opposite shoulder was untouched. She dropped dead, so not technically a bullet failure, but not getting exit wounds is no bueno. Heck, the opposite shoulder showed ZERO damage.
2) Same loadout as #1. Spike WT deer. The broadside shot did have an exit wound. The near shoulder was absolute mush, with the far shoulder hardly effected. (I'd rather the near shoulder show moderate damage, with the far shoulder getting absolutely wrecked).
3) Broadside neck shot on ~100 pound boar. 85 yards. 308 Win. shooting 150 Interlock. Bullet did not exit. Instead of mushrooming, the bullet pretty much pancaked. Retained bullet held together but over-expanded.
4) Same story #3 except broadside shoulder on ~120 lb. WT buck. Pancake with no exit wound.
The terminal performance of 308 168 Gold Dots has been really good so, but the sample size isn't that large.
