It's fact that shortening barrels does reduce velocity, but really efficient cartridges like the .308 will suffer minimal loss ans sometimes only 15 fps depending on the load... The barrel needs removed from the gun and can be cut to near a finished length with a band saw... Then put in a lathe for the cut end to be squared to an exact desired length and the desired contour of the muzzle to me made... As said prior, re-crowning for a perfectly symmetrical rifle groove ends by a competent gunsmith or machinist is a requirement... Upon the bullet's exit, it needs to break free of all the riflings at the exact same time and an uneven crown cut would prevent this...
