[QUOTE="Alibiiv, post: 2209159, member: 69192"] You might want to check the ballistics between the two cartridges before you go down that road. There's really not that much difference in ballistics between the two cartridges;[I][U] .270 AI and the 27 Nosler[/U][/I]. While you are checking the ballistics make sure that you are checking apples for apples because from the data that I have found there's not a great difference between the two cartridges. And yes there is a difference in performance, however it comes with a price.[I] (1) presently $92 for 25 pieces of brass (2) with a 150gr ABLR it takes 88.5gr of RL50 to get 3362fps out of a 26 inch Lilja barrel (3) then there is the recoil from all that powder,[/I] and.......I am not so sure about barrel life however do not suspect it will be too great with that speed and that much powder going down the tube. With the .270 Ackley I am getting close to the same performance out of a [I]26 inch Lilja and a 150gr ABLR with 57gr of RL19 and brass is $87 for 50 pieces brass[/I].
