RE: Scope Sighting Question
Shoot all three back to back.
I have a Browning A-bolt .223. It hates Winchester ballistic silver tips. It will shoot other bullets of the same size, but not the Winchesters. It will shoot the cheapest ammo money can buy better, even the Russian surplus ammo. When I first got the gun, I tried Winchester, Federal, Remington, and Hornady each in a variety of bullets. The same gun that will shoot a clover leaf with Hornadys will be lucky to get a 2" group from the Winchesters.
