All

I have been searching all over the net and talked to a couple of gunsmiths; but I can't seem to get a firm answer on this.

I am having some work done on my rifle and would like to take some length off the barrel...so here's my question...

What, realistically, could I cut my barrel down to and still be able to get 2350-2400 fps out of it (without driving pressure way up)?

I know all barrels are different and some are faster than others.

Any info would be appreciated.
