I have finally Decided on getting a 243. win for Predator hunting. Im going with a Remington Model 700 SPS Varmint which comes with a 1:9 1/8" twist barrel. I was planning on trying everything from 55-95 grain bullets. What im really aiming for is around 70 grain Nosler Ballistic Tips. Will a 1:9 1/8 twist stabilize a 70 grain bullet. What should it stabilize the best?
