Evan you will need an 8 twist for 80 gr. bullets and a 7 twist if you want to try the 90 gr. bullets. You need to get a Savage action and have it gone through. Then when you want to try a different round you can change the barrels yourself. Right now I`m pushing 80 gr. Berger bullets at 3,250. I can push them to about 3,600 fps. but they are most accurate at 3,250. With slower bullets you just hold higher.
