Home Forums Hunting & Shooting Long Range Hunting Smaller dispersion at longer range than at close range.

What if the blast at the muzzle is not upsetting the stability of the bullet or its angle of dispersion but is just nudging the stable bullet off line slightly?

A perfectly straight launched bullet nudged over/up/down .001" would cause some of the "MOA shrinkage" at longer range. Something like that could cause a .75MOA group at 100 to go on to be a .5MOA at 300. Once the bullet is out of the blast zone there is no other force but wind and air pressure to act on it.
