    Ok, I have heard that the 223 is more accurate and hits harder. I don't know much about ballistics but I would think that this isn't true? Whats your opinionon this?

    depends on the gun.

    a 223 out of a precision varmint type 24" rifle will be more accurate and hit harder than a 308 out of a 1.5" short barreled rifle...

    while on the other hand a precision varmint type 24" barrel 308 will be more accurate and hit harder than a 223 out of a 1.5" short barreled rifle...

    the truth doth lay somewhere in the middle

    So say out of a remimgton 700 varmint the 308 would win out over the 223?

    Definitely will hit harder than 223 out of that combination.

    The ballistics table in my horniday catalog shows the .223 superformamce cartridge with a 55gr gmx bullet traveling 2872fps carrying 1007ft lbs of energy at 100 yards while the .308 superformamce with a 150gr gmx bullet is moving 2715fps and has 2455ft lbs of energy at 100 yards as well. Hope this helps

    Your welcome. At 300 yards 150 grain 308 hits almost exactly twice as hard as a 60 gr 223 at the same distance

    That is significant. The person saying this may have been referring to an sporting rifle.

    Still same power equation. They apparently was tryin to make you think they know what they are talkin bout. Better to ask us on here like you did than someone you don't know if they kbow their stuff.

    Most people can quote the book too but don't know squat on the REAL world velocities and impact power levels are. That's what I deal in-if I give you velocities/impact power it will be real world levels. Several others are the same way.

    Ok, what are your thoughts about the 308 for a long range cartridge vs a 30 06.

    Same ballistics basically w the 308 being flatter shooting and a little less impact power out past bout 300 yards.

    I have always wondered why it is flatter shooting.

    30-06 has a very slight edge due to a bigger case capacity so it can reach a scootch farther. The real advantage in 30-06 vs 308 comes in using bullets heavier than 168 grains. The bigger case capacity of the 30-06 really starts to shine and totally leaves the 308 behind when you get to 175-220 grains.

    168 and down there is no practical difference.

    That's alright. It gets the point across just fine. Moat folks don't know the difference anyways. At least you looked wo juat spouting off bout it.
