ive been bouncing back and forth between these two out of a 270WSM. the 140gr accubond performs flawlessly, but out of a bench rest, i get much better long range groups out of the accutip. i was getting a sub 6 inch group at 600 yards with the remington factory ammo and knocked down 3 critters with the accutip this year. All 3 shots hit bone and the accutip destroyed the shoulders and spines without coming apart. Last year i hit a bull elk in the spine with the accubond and dropped it in its tracks. so in my experience, both work just fine, but the accutip (SST) seems to fly a little better at long range. but at 300 yards and under, its hard to pick between the two...
