    Just wanted to see if anyone has any information on a barrel for a 338 SnipeTac ??
    Right now im looking at a Lilja 32" with a 1-10" twist that will be on a Stiller Tac 408 action and aiming to throw 300gr Bergers around 3300 fps.
    I want to know if theres an optimal length and twist for this caliber.
    Also very curious about carbon wraped barrels ?

    34 inches excellent accuracy you will get about 700 rounds before you will have to replace the barrel

    At that velocity a 1:11 twist would work great - a word of advice on the carbon wrapped barrel - stay away.....

    I have a 1-11 in my snipetac..

    load 136 50bmg = 3200fps..

    im not sure how you guys are running 3300fps+

    I CAN load up hotter but brass life goes out the window...

    I can get 3300 with us869 with ES isn't good and temp sensitive..

    all accurate though...
