Majd - are you seeing any barrel bend/flex as you power the pipe up that much? I assume thats stock Pathos 28mm ID carbon pipe you're using?

Given your results I assume if there is any barrel distortion its not affecting the accuracy even on long shots.

Am using alum pipe [Rob Allen, slightly thicker wall 28mm ID than Pathos] on my DR mech pipegun project, and just a bit concerned that barrel stiffness may hamper things as I load things up with that mech? seem to recall that was an issue in the old days messing around with twin 20mm bands on aly railguns, hence Rabi and others bringing out crazy heavy pipes, which of course sank like a stone

muzzle band slot is tight horizontal so both bands pulling from as close to shaft axis as possible......
