On that note do you think that the case shrinking, and causing less volume inside the case could be leading to these spikes? Similar to going from Hornady to ADG? The powder charge and primer remaining the same in a possibly smaller case and smaller chamber and smaller bore?Problem with that theory is that while the bore may shrink, so does the diameter of the bullet and cartridge case, and likely by more than the bore, unless you are keeping the ammo warmed somehow..
