    Default Ammo question

    .308 win, and .308 win "boat tail" can both be shot outta a 700 chambered for .308 correct? All i've been able to find lately is the boat tail, and wanna confirm before i "send it!". Looks the same size, maybe a tad shorter, and necked down.

    Thanks!

    That's correct. The "boat tail" means the back portion of the bullet is angled inward. This provides better accuracy. No difference in the case. I reload .308 with boat tail bullets.

    You're fine to shoot this from any .308 rifle.

    Boattail does not increase accuracy, it increase areodynamics. Just like a sedan is more aerodynamic than a hatchback. In fact, boat tail bullets could be less accurate. The area where the bullets dig into the rifling is called the bearing area or bearing surface. Some guns with less than ideal bores, even brand new rifles, can have a bit less accuracy. it all depends on what the gun likes. A well made gun with a well machined and finished bore probably won't care much. A gun with a not so well machined bore or a particular bad spot in the rifling could shoot worse with boat tails. It would compare to car with longer wheel bases or even more so motorcycles. the longer that contact area, the more stable it is.

    Far as bullet drop and wind drift goes, you wont start to notice the difference until you hit 300-350 yards.

    I would disagree that it does not affect accuracy. If you have a rifle sighted in at 100 yards, and then go out to 300, the lessened drag would make the zero more true with the BT round.

    In either case, yes, you are fine.

    Thanks. The cartridge is necked down a bit closer to the primer, and overall primer to bullet nose is a bit smaller and it got me a bit paranoid.

    A necked down cartridge refers to the diameter of the bullet.


    Most Bench Rest shooters use flat based bullets.
