We are so lucky to have a great many excellent bullets to choose from! I have not used 110 ABs. I have limited experience with the 140 AB out of a 270 and am a fan. But if you wanna play with 110 grainers out of a 270, go with the TTSX - especially if you have a 24" barrel. It'll make your 270 think its a 257 Weatherby. As others have noted, of course, the BC catches up with you at long range.
