Move from short to long barrel

[shooterfpga]

I ran a 26" 1/10 with my 308. I ran 178's just under 2700FPS. If you use a 308 for long range work/practice an extra 50-100FPS will make a difference in your hit percentage for sure. I run a 27" barrel with break on my 243 Competition rifle. The only reason I would build with a short barrel would be for a short range brush gun.

Was this factory or aftermarket 26" i need that extra oommph between 900-950 because i seem to be dropping from transsonic at that distance.
