From Winchester Super X to Federal
PAW PAW makes an interesting post.
An instructor at the local sheriff dept told me recently they had noticed Winchester SuperX threw a much wider pattern than Federal. They have since switched to Federal for their agency in order to have the tighter pattern. I have not yet experimented with the Federal ammo.
I am seeing semi-transparent cases containing buckshot without any buffering granules. It is competitively priced. I havent bought any for testing yet. It appears to be a European brand.
Will buffering granules have anything to do with the size of the pattern? It is my understanding that buffering granuels reduce shot-to-shot pellet deformation on ignition.
