I just purchased a Savage Edge in 22-250, the twist is a 1 in 12". What would be the ideal bullet weight for this rate of twist. The manual is recommending that 40 grain Federal V Shock Nosler Ballistic Tip. I thought the rate is a little fast for a 40 grain pill, I was thinking something closer to 55 grain. If anyone has any experience with the 22-250, Savage Edge, or a factory ammo that would work in this combo please let me know. I am going to shoot factory ammo from this gun, but I am still hoping to get one inch groups at a 100 yards.
