BEst factory 270 load for a carbine

[PSE]

i just bought a stery mannlicher w/ a 20" bbl. what would be the most efficiant and effective factory load. i am looking for a round thats not gonna create a ball o' fire when the rifle is shot. i know most 270s have longer bbls and i am concerned that the 20" may not be able to burn all the powder.

I think they are all loaded to pretty much the same . I would pick them by the bullet
