Thread: Barrel chop

Have just had my 308 barrel chopped from 24 inch to 20 inch to add a suppressor.
It is nicely balanced and a good compact rifle now.
I was a bit disappointed when testing the loads out through the chronograph to see the velocity has dropped 200 fps.
The 150 gn were doing 2820 fps but dropped to 2620 fps.

Was told barrel chopping doesn't effect the 308 as much.
Do I accept the lower velocity or change powder loads?
