    believe it or not?

    Following on from the 30mm scope tube and light transmission discusion what other myths /wives tales are floating around?

    Heres one to start off the discussion:

    If you shorten your barrel you can regain the lost velocity by changing to a powder with a faster burn rate.... fact or fiction?

    Firearm manufactures all over the world spend mega dollars on engineers and their reports before they build a rifle and yet there are DIY's who attack these rifles with hacksaws at every opportunity because they know best.

    Yup Spook. I could never figure it out either. Every one of my firearms is exactly as the manufacturer built it and although I can't explain it, for some reason they seem to work.

    What more do we need? If we are above ground and breathing the rest is up to us!
    Rule 1: Treat every firearm as loaded
    Rule 2: Always point firearms in a safe direction
    Rule 3: Load a firearm only when ready to fire
    Rule 4: Identify your target beyond all doubt
    Rule 5: Check your firing zone
    Rule 6: Store firearms and ammunition safely
    Rule 7: Avoid alcohol and drugs when handling firearms

    In my mind barrel lengths on most hunting rifles are dictated by custom as much as anything else,and them factory ammo is built around that length barrel.

    Eg my main hunting rifle is a browning blr takedown in .308 and it had a 20" barrel-it now has a 15" barrel and with reloads and a suppresser I'm getting a few fps more than I did with factory ammo.

    Play with quickload and the fastest load with a 12 inch barrel will still be the fastest from a 24 inch

    Yes you can fiddle around the edges a bit but best velocity burn rate is dictated by the chamber bullet relationship, barrel length is mostly irrelevant.
    Often see the " chop it and get the speed back with a faster powder" quoted though.

    Could be other reasons to use a slightly faster burn though like reduced muzzle flash?

    Yes, well, they will all perform better if you were to cut a piece off the end...or weld a piece on.

    If it were the case Im sure all the competitive shooters would have the shortest barrel they could for stiffness less leverage on action etc
    But they don't seem to.

    Funny thing, my target rifle has a short barrel with a tube extending out past it to extend the sight radius. It's a factory anschutz set up so hardly a buba job

    Rimfire?

    There will be an optimum length for velocity for any given cartridge.
    While i think you can get SOME speed back with faster powder in your normal big game cals your always goin to loose over factory length and optimum charge of optimum powder.

    You need to remember that these manufacturers are there to make a profit (a big one) not neccesarily to create the best performing firearm.

    I think there are improvements to be made to pretty much any off the shelf firearm.
