nothing wrong with the 270, but no 270 bullet can compare in the offerings in 6.5, 7mm, and 30 cal, the only reason the data even looks favorable to the 270 in the cherry picked loads is the fact that he used the superperformance loads in the 270 and then I will guarantee you those loads won't shoot nearly that fast in an average factory chamber.......in the world of long range trajectory muzzle velocity don't mean much, BC will outrun it every time, and great long range bullets in .277 diameter are as scarce as hens teeth, the 169 & 190 wildcats are awesome but ya need a specialized twist to shoot them, like a 1:6 in the 270 winny
