I have a 270 in an old a-bolt medallion, a 6.5 swede in a model 70 classic featherweight. Also had a 260 in a browning synthetic stalker. All 3 shot great, and killed deer dead. I will say I had more bang flops with the 270 and standard cup and core bullets than with any other caliber. The 260 had them beat in groups on average, but all 3 had loads they shot under an inch. I gave the 260 to my brother I killed 20 deer with it. The old 270 is retired now with 24 kills and only 2 blood trails which is awesome caliber testimony I believe. My go to gun is the swede mainly because I love the fact it is such an old classic and I love the model 70 classic featherweight. Even though its not a real "classic" featherweight it feels and shoots great with old hornady soft points and H4831. Whichever u choose will kill any deer that ever walked as far as u can accurately shoot. Good luck!
