I'm sure this is not a new thought process .. and confess I haven't searched to see what has been discussed before.
Is approx 24" and thereabouts an optimum length of barrel (let's loosely stay withing the 30 cal area)? I guess it is. I only ask because IF we had a barrel near twice as long (forget for now probs re weight, support etc) ... and IF we had stronger chambering ..... and IF we had a slower powder in a larger case ... then could we expect that the bullet's acceleration phase could be extended that much ... so we have a very marked increase in velocity potential. Thence longer range and energy levels.
Acceleration obviously ceases at the muzzle .. it's all downhill from there! But could we extend a gas burn long enough ... and get enough volume of gas .... to maintain acceleration that long/far?
I am tempted by thoughts of barrel resonance problems .. decreasing accuracy .... but in principle .... what are the pro's and cons ... again leaving aside ergonomic factors.
Rifle guru's ... what say you? .... and sorry if this is an old subject.
