I've taken a number of deer with this "older" design loaded in 12ga Federal slug loads (not the same dia or weight, I know). Performed flawlessly - excellent accuracy, expansion and blood trail (large spray pattern behind where deer was standing). Since then I have used the 285 spitfire and 290 TMZ in my 50 cal ML. Last year took 6 point at around 10 yards with Spitfire and 90g TS at 1600 fps (Neck shot, dropped in his tracks, but no exit wound and never recovered bullet???). This year 90 yd shot at doe, she went 15 yds, but no blood trail and exit wound was smaller than entrance. I know I should be happy, but I hunt in some thick areas and a good blood trail is very important. The 290 TMZ was pushed by 100g BH 209 at 1780fps (chronographed). Called Barnes and they said at higher velocities the petals initially open fully and then may fold back to sides, thus a smaller exit wound. I will go back to the ole 300g Expanders. I believe, but will confirm, that the bases of the petals are thicker and keep them from folding to the sides too easily. Hope this helps.
