Picher, if pressure points can reduce amplitude of barrel vibrations, causing different bullet weights and loads to shoot closer to the same POI, that's interesting. I've never heard of this before.
How did you measure barrel vibration amplitudes to see they were made smaller?
How much closer do different loads shoot to each other with pressure points on the barrel?
Do several loads shoot within 1/2 MOA of each other at 100 yards?
And how do you keep the pressure at each point on the barrel the same force in all shooting positions?
