Theoretical 308 round question.

[dvdcrr]

If you fire a 150 gr. 308 round at a 45 degree angle how far will it go before it hits the ground. Feel free to insert relevant details assumptions. Zero wind.

I don't reload, yet. I don't use a bench rest. I shoot a Ruger Scout from 100 to 300 yds; 100 and 200 with the factory ghost ring, and to 300 w/ a 2.5 X 28 scout scope... I have no real ballistics data but I'm guessing a mile to a mile-and-a-half.

?

2.6-3.52 miles. i guess.

For what it's worth, if you're looking for maximum range, it's not at a 45 degree angle. A 45 degree angle would provide maximum range in a vacuum. When you factor in air resistance the angle for maximum range decreases.

Hatcher quotes the results of a study on the Swiss military round from the early 1900s. Ballistics are pretty similar to the .308. The 174 grain, .30 cal bullet with a muzzle velocity of 2600 attained a maximum range of 4457 yards (2.53 miles) at an elevation angle of just under 35 degrees. Velocity at impact was 417fps.

Need a lot more info, muzzle velocity, and ballistic coefficient of the bullet are critical. Factory loads start at 2700 fps and some better handloads exceed 3000 fps. A quality target bullet will have a much more aerodynamic shape than typical hunting bullets.

This. Max range will be achieved at 30*-35*

Need:

Launch velocity
BC or bullet type

Maximum range of the early .30-06 is 3500 yards.
The .308 has very nearly the same ballistics.

 

[lysanderxiii]

Maximum range of the early .30-06 is 3500 yards.
The .308 has very nearly the same ballistics.

3500 yards is for M2 Ball (152 grain flat base FMJ), or M1906 Ball (150 grain flat base FMJ).

With M1 Ball (173 grain FMJ-BT) the maximum range is 5,500 yards

 

[Jim Watson]

Yes.
I figure commercial .308 Winchester loaded with a 150 grain flatbase spitzer will shoot pretty close to 1906. Military 7.62 with 147 grain boattail a bit farther but not enough to matter on the keyboard.
173 gr M1/NM not in play in the OP.

 

[lysanderxiii]

M118LR is a very close ballistic match to M1 Ball (more accurate though).

Just tossing it out there....

Does this have anything to do with the recent DARPA Exacto test? I wondered the same thing.
