.308 VS 7mm-08

Texas Hunter
What is the advantage of one over the other as far as a hunting round is concerned??
When i mention hunting it is in reference to whitetails,mule deer,and occasional varmint hunting.
Never having owned a 7mm-08(i will soon though)i have looked at the ballistics in factory loadings and cant see much difference really.
Any help will be appreciated.

    SIX OF ONE AND 1/2 DOZEN OF THE OTHER, 7/08 HANDELS LIGTER BULLETS BETTER (139 GN. HORNADY IS A FAVORITE OF MINE) WHILE THE .308 COMES ON WITH 150 GN BULLETS.

    Your own observations about not much difference are pretty accurate. As you are probably aware, the 7mm-08 is a .308 necked down for a 7mm bullet. As is usually the case in this type of "improvement" the cartridge of smaller bore handles lighter weight bullets at a little higher velocities with a little flatter trajectory, whereas the larger bore permits the use of larger bullets. You usually can't use the larger bullets in the smaller bore; because, as you add grains of weight the smaller bore bullet can't get fatter, so it's got to get longer. If it gets too long the ideal twist rate of the smaller caliber's barrel will no longer stabilize it, so it becomes impractical--and you need the larger caliber's barrel for the heavier bullet. In the case of these two cartridges an overlap exists right around 140-150 gr. bullets, and in that area there isn't much to chose from. Either cartridge makes a fine deer rifle.

    I recently posted re 7mm-08 hunting rifles and I chose a Tikka T3 in S/SS.
    I mounted a Burris FF2 3X9.
    The rifle shoots great and the ammo selection is good.
    Ammo selection is much broader amd a little cheaper for .308.
    I will use this rifle for deer hunting and it is a pleasure to shoot at the range.
    I may consider elk hunting as I become more comfortable with the rifle.
    The Hornady light magnum rds @3000fps give me ballistics between .270 and 7mm mag.
    I may start reloading and experiment with different bullets.
    I am very happy I went with this combo.

    As I understand the story, the 7mm08 is a wildcat cartridge generated by the silhouette crowd. A 7mm projectile has a better ballistics coefficient then a .30 cal projectile, so theoretically the cartridge would have the inherent ability to be "accurate"! ...theoretically.
    As far as hunting goes ...6 of one or half dozen of the other(as already stated). Good Luck! ...Mark

    You are correct... it was been used by IHMSA competitors for about 30 years now. Back in the early 1980s, I got really tired of making brass for my 7mm BR chambered Remington XP-100 silhouette pistol, so I had it rechambered to 7mm-08... quite a handful[:D], but man did it ever shoot good[:p]! I shot my first 40x40 score with it[^]

    I think more highly of the 7-08 as a Hunting round,than I do the 308.

    It offers great performance,with modest recoil and there isn't much that will shake either the 120XBT or 140XLC. Here's my then 11yr old,with some tidy work done via 20" 7-08/140XLC combo,early last Spring.

    The 308 gets the nod(from me),when utilizing the readily abundant mil-surp fodder,at a great savings. When loading,my preference is definately 7-08.......................

    Recoil , recoil, recoil
    the 7mm shoots with alot "less" recoil amd when shooting competition , it helps in the long run .

    Boy ! Big stick , I sure don't like seeing that rifle pointing at that youngster, even with the bolt back .

    Looks to me like the gun isn't pointing at the youngster. Looks to me like his legs are below the imaginary line coming from the muzzle.

    Obvious that he is both behind and below the muzzle,with the bolt obviously opened.

    It ain't his first foray,nor mine and safety is paramount..................
