Hey all.

Couple questions about a .243 Barrel.

I've had a 110 in my cabinet for awhile now. Getting ready to dig into the build.

I'm looking at creating a 1000 yard gun. (I'm still unsure about using a .243 AI or a .243 Win. So, with that, i'll be pretty general about my questions.)

With the .243, what length of barrel should i be shooting to obtain maximum velocity? I've ready everything from a 20" barrel to a 26" barrel.

And, with that, I'm wondering what twist i should use. I would like to be able to shoot a heavier bullet, and at the same time be able to load a light bullet, and maintain excellent accuracy.

Thanks in advance.
