Hello
I just got a new .233 WSSM for christmas. I have been looking for ballistics on it but i am having some trouble. I have only found one chart that winchester has. If someone could please help me out with any info. I want a 150 yard zero and was wondering where to sight it in at 25 yards. Thanks in advance
Marcus

This would be your best zero with the same load.
