After a lot of work for zeroing here is the final results. The first shot down-right it was by mistake.
I used a Kestrel 4000 and a Leupold spotting scope for help.
Also i took the informations that i needed from Ballistic Calculator for shooting from 300 yard.
You have right Rich. We had and a AI with a S&B PM II scope on it and it was a lot better from Leupold.
I am thinking to order this .
Randy, the rifle is .308 WIN.
For this excellent group i used Remington PREMIER MATCH ammo (RM308W7).

PS: About the diopter i am looking for S&B USMC model. It has the USMC logo on it. Has anyone seen it on the web? I can not find it nowhere.
