I'm considering building a 243AI on Gikes Ross Action with 33inch Broughton 5C barrel 1:7.5twist set up for the 115-117grain DTACS is barrel too long for the .243AI I figured given the increased pressure of the AI configuration coupled with increased pressure of the heavier bullets I would achieve better results with 33inch barrel than say 30-31inch and could achieve higher velocities?
Does anyone have suggestions or reasons why the extra 2-3 inches would be unnecessary or reasonable?
thanks
