Hello I have purchased a savage 110fp in 223. This rifle was previously owned by a LEO that was supposed to be a very good shot. He passed several years ago I bought it from the person that bought it from his wife. It has a F prefix and is a later model. As far as I know it's not been worked on . It has a warne 20moa steel rail on it . I'm not sure of the twist rate there is nothing on the rifle. It still has the factory stock on it not really a fan of it but if it shoots as good as my friend says I can probably get used to it. What would be a good bullet to start working up loads with. I have 55gr fmjbt 40gr fbhp 50gr wsp and 88gr eld match for powders I have varget IMR4895 IMR4064 CFE223 . Thanks
