    WOW ... now this is truly sweet. I wonder if the last 2 are selling the same barrel ... ???

    The barrel sold by Fulton Armory is a Criterion with a 1-8" twist. These last 2 are 1-7". Price is not bad and again, unless you want a pure Colt that will have a 1-12" twist you're going to be able to shoot a wider variety of loads with the faster twist barrels.

    Personally I want a 1/7 or 1/8 twist. I shoot a lot of heaver bullets and dont want a slow twist to limit me on what I can shoot. Trying to keep track of different ammo and mags for different guns would be a real pain!

    Yes I agree. This has been my reasoning exactly.

    Here is a 1/9 twist chrome lined barrel
    personally I think 1/9 is better for a range rifle
    1/7 you are limited to 62+ grain bullets
    1/9 you can shoot the more common 55 to 75 grain bullets

    Your information is incorrect. A 1/7 barrel offers more versatility than a 1/9.

    Im not going to into a pissing match about this but I will say this
    the only reason the military went with the 1/7 was because the rounds the military used didn't work well under extreme cold with a faster twist and I believe also tracer rounds stabilized better with 1/7
    1/8 would be the ideal but 1/9 will work better with common 55, 62, and 69 grain bullets
    I see you are a master armorer and prior service so I will show you respect you didn't show me and leave it at that
    but I have offered in my prior post another option besides 1/7 and 1/12 twist barrels

    Regarding projectile weight(s) and barrel twist ... I'll leave this here (you may have to actually cut and paste the entire link).

    Hope it helps: ammo-oracle.razoreye.net
