I have not gotten an action yet, but probably will start with a target action. Rifle will be primarily for range use and possible occasional varmint. I want to have the option to shoot up to the 77-80 gr bullet. I am hoping to be able to try some shooting to at least 600 yards. I am looking at the 223 Improved primarily because of the heavier bullets.
With an 8 twist barrel what range of bullets should I hope to be able to use?
Also what length barrel would you recommend for the caliber?
