Just wondering if someone could post some load data for how far their .308 can stay supersonic. I know the usual is about 1100, but does anyone have load data to show supersonic speeds past 1300 or 1400 (under I assume near perfect conditions).
.308 load data out past 1000

- Start date
Re: .308 load data supersonic
This is a .308 load from heaven ( even at standard atmospherics).

Re: .308 load data supersonic
Thank you very much. I had a few friends that didn't believe it could stay supersonic near those distances, and wanted a little proof.

Re: .308 load data supersonic
What powder charge were you using to get 2600FPS out of a 230?
That's impressively fast.

Re: .308 load data supersonic
That load is still in development and is very hot out of a very long barrel throated for this bullet especially.
This was 46.3gr of RL17.

Re: .308 load data supersonic
Is there some more data for anyone who has gotten their .308 supersonic past 1350?

Re: .308 load data out past 1000
This is DOPE from my 17" .308 1:10 Krieger firing a 208 amax @ 2500
Goes subsonic at 1200+, I've seen guys pushing the 208 up to 2700 out of their long barrel 308, that would put supersonic flight out to 1400 at sea level.

Thank you
Is there just one more person who can provide load data for supersonic at 1350 or 1400?

Perhaps you should have a look at ExBal???? And you can find all this yourself......

Re: .308 load data out past 1000
I am just starting out to LR shooting and don't know very much. So far my rifle and I have only been up to 400 yards. I'm wanting to see what rounds are capable of staying supersonic at those distances, and because I don't reload or know how, I was hoping someone on here could provide some data.
That, and a few people I know don't believe it can stay supersonic out to 1350 or 1400, so I'm trying to give them proof it can.
