Here are some comparisons of the frontal area of a few 270 bullets. All fired from the same rifle. The 130 grain with all the same charge. I don't have a live test medium. So I had to set jugs of water up at 100 yards. Our little deer don't catch many bullets. Fairly controlled results though,and the differences in frontal area are varied no doubt.

Left to right is a 110 gr TTSX, 130 gr Accubond, 130 gr old school Grand Slam, and the Tipped Trophy Bonded. All the 130 gr bullets were launched via 55 gr of IMR 4350. The 110 TTSX was sitting on 57.5 gr of RL17. I don't have any e-tips to compare. Though I've considered trying them. The big rivet of the Trophy Bonded has been accused of veering off path in game. Anyone have any first hand experience with that?
