Having used Interlocks for years in .25, 6.5mm, 7mm, .270, and .30, I've never felt the need for anything else. I've fiddled with others, but I've seen no better results. 130s in .270 and 139 in 7mm are the go-to bullets, although Jon Sundra wrote several years ago that he's killed more game of all sizes (not dangerous) with the 154gr Interlock than any other bullet.
