I purchased a 243 Tikka last week. It has a 1 in 10 rate of twist. Am I correct in assuming that it should shoot a 95-100 grain bullet the best or am I mistaken? I would like to shoot a lighter weight bullet but I am not sure it will with a 1 in 10 twist. I am a novice on twist rates so any help you can give my would be appreciated.
I am going to use the gun for coyote hunting. The gun is light and easy to carry. My other guns are to heavy to carry all day.
Your rifle should shoot 75-90gn pretty good. I recently acquired a Winchester HVB in .243Win that shoots the 87gn great. I've tried the 65gn VMax and they hovered just under an inch but the 87gn Winchester pills printed in the .2" range. I worked up a load with the 90gn Ballistic Tip and they're hovering around .2-.3". I'm using 44.5gn of IMR4831 with the 87gn and 44.0 with the 90gn. This powder and bullet weight range also worked just as good in another .243 Win that I used to have. It was a Rem 700 (9.25" twist). Good luck. JohnnyK.
