Thread: 1-14 twist 19" barrel .243 projectile weight for deer under 200m

Zero percent chance your .243 is a 1:14" twist if it is original.

Start again with the twist rate check buddy, find something that will work.

The history of the .243 Win is all about the 1:10" twist. The failed .244 Rem was 1:12" but the .243 Win was always 1:10" which is why it succeeded. Then Remington introduced 1:9.125" and Savage with the 1:9.25". None of the main manufacturers ever produced a 1:14" .243.

I'll eat my stinky hat if your rifle is 1:14" with an original barrel. If someone has rechambered a 1:14" twist 6mm barrel in .243, then its a bodged up varmint rifle. Sorry to be so blunt. Doesn't mean to say you can't use it to shoot deer, you just need to treat it like a "6mm 22-250" and shoot superfast 50 or 60 grain bullets and head / neck shoot them.
