Now you guys saying this it seems almost obvious that there is a better seal for added pressure.
If you think about the angle of the land to the bore, it is more sloped, less angle. With that the bullet can seal better. Think of a balloon in a square box. When you blow it up the inside corners don't touch the balloon. If it were in an Octagon shape the slopped edges would let he balloon get closer in the corners and have more surface and less gap.
Just a thought if the bullet seals in the barrel and lands better causing more pressure to build up, I guess more velocity with the 5R..
