Its so good to see that folks still use the good ole 270.
270 has killed plenty of animals all over the world.
The only 270 I have now loves IMR4350 and 150 gr Partitions but I would bet they will shoot Nosler Accubonds just as well.130 gr has taken plenty big animals also.
As others have said the amount of powder, and make of powder,primer as well as how close to Lands to load will be your indicator for accuracy.
Its a journey so enjoy your journey and keep all posted as to what works best for your rifle.
Just my 2 cents
