. dependent on load pressure (high-low)

. Blued or stainless (heat retention/dispersion)

The issue of a barrel walking/moving/twisting due to heat causing a change in POI.
Is this real or as any metal tube that is heated does the effect of the rifling on the projectile just reduce/relax due to expansion therefore a change in the pressure/friction (bore increases in size)effect on the projectile (same as pressure change due to powder load and the effect it can have on accuracy.

3 Shots for a hunting rifle/gong rifle .5-.75 moa, obviously less is more

5 shots for a competition benchrest rifle after 2 or three "sighters" .0 to .1 moa less is really more in this case.

Shot as they would normally be shot ie for a hunting rifle, boom....bugger... boom...oh shit...boom....!!!!

No point waiting for them to cool or shooting off 15lbs of sand bags etc, shot as they would be in the field ie with bipod & rear bag/fist
