    Using Remington and winchester or Norma lapua because or the thinner walls is sometimes the one way to keep a 308 super sonic to 1000 yards winchester a always thought was the inferior casing because of its .0125 wall thickness and Remington being the best because of its .0145 wall could be reloaded more but to my surprise the two to three grains that the thinner walled winchester and Norma lapua is the way to get the longest shots you just have to learn to care for the brass so it will last

    thanks Jason!

    Yah thanks, Jason. For adding to a topic that's already been discussed 2 years ago!

    No Thanks Jason.

    What powder are you using? You can still load too hot with even "lower capacity" LC cases. So there is no point in using Winchester brass and having extra case capacity

    Also, Win and Rem brass are known as low quality brass that won't last ling. The best brass for longevity is Military LC brass, stuff lasts forever.

    Cartmann is spot on here. I use the same loads in all my 7.62x51 and 308 marked rifles and have no issues or pressure signs.

    Yup.
    Or you can go Lapua, and get the best of both worlds.
    Their walls are thinner, but the superiority comes from metalurgy instead of bulking up.

    I hate paying for them though.
    Do you really think we want laws to be observed? We want them broken. There's no way to rule innocent men. The only power any government has is the power to crack down on criminals. When there aren't enough criminals, one makes them. One declares so many things to be crimes that it becomes impossible for men to live without breaking laws. Who wants law-abiding citizens? Pass the kind of laws that canít be observed, enforced, or objectively interpreted - and you create a nation of law-breakers.

    They are more consistent for sure, but they are not as strong as LC. A lot of people don't know how to size LC brass because they can be tough to size and requires a certain technique, as well as extra lube.

    I use mainly LC 308 brass in semi autos and Remington in bolt guns. The only tin that gets Lapua brass is my 338LM. I do batch the LC an Rem brass for consistency though.

    I don't know how you're measuring strength (CUP pressure it'll take, etc) but I get my Lapua brass to take more loadings before the necks crack, so that's why I said "just as strong". Maybe "just as long of a life" would have been a better worded statement.

    I'm not loading the Lapua brass light though. I'm barely under 2700 fps with 175 SMKs using Varget. IIRC, I couldn't get that much Varget in LC casings, to get it to that velocity with that bullet and COAL. Might have to try and find my old data to make sure, but that's what I believe I remember.

    I don't know how you measure strength... LC brass is thick all the way through from top to bottom. Once fired LC brass shot from a M240 or M60 machine gun with out of spec, and loose headspace, is very tough to re-size. few people know the technique to resize this ballooned up and strong brass.

    If lapua was shot from a M60 with loose headspace, it would break after the first re-size.

    But then again, you would not know this because you are an Amateur.

    Please Discuss....

    No thank you, I prefer to have honest conversations with intelligent people.
    That means you're doubly excluded.
