I know that a shooting several shot strings from sported weight barrels causes the POI to change as the barrel gets hotter.
When I shoot my .308 that has a heavy varmint contour barrel, measuring .875" at the muzzle, the poi does not shift, no matter how many rounds I send down range.
I know that any heavier countlur iaides in recoil management,
But how much lighter can a barrel be and still not change it's POI when shooting several shots in rapid succession?
Can the rem varmint contour (.820 at muzzle) do it?
