I'm interested in either one of these for my 7mm Express ( .280) I can get the 150 ABLR/154 SST to 2900 with R22 and the Speer 145BT to 2950 with IMR 4350. I get the 168 ABLR(R22) and my most accurate 160PT(imr 4350) to 2750... Since it seems to provide better speed with the 150's or so, I'd like to have a good load with either just for elk. I have a lot of experience with Barnes and I have always had good results with the TSX/TTSX. I like the looks of it but I see the Etip has no relief grooves. Is it a "sticky" bullet like the older Barnes X or Scirocco? I am after all the weight I can shoot the fastest, but I'm afraid to try the 160 TSX because of this rifes history. Now, that 168 ABLR is a flat shooter even at 2750, but I'm not sure it would work for a hard angling shot on elk or break shoulders up close. Am I overthinking this one? My main elk rifle is my Whelen AI, but its good to have a spare. Long way around to ask if the E Tips are as easy to get to shoot fast/well as the TSX/TTSX? Thanks. BTW, I saw a Kimber Montana at the LGS in .280 Ackley! OMG...my brain is pondering "any" excuse/reason to trade up, lol.
