Thread: Rule of Thumb!?

So what's your's for attaining the so called accuracy of your rifle?

MOA
. 3 Shots
. 5 Shots

Time
. between each round fired
. barrel temperature?
. dependent on Caliber?
. dependent on load pressure (high-low)
. dependent on barrel couture (taper/thickness/fluting)
. 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.
