RE: .50 cal. Optima Pro loads
From what I’ve read I assume you are not allowed to shoot a sabots. I have the same gun you do and I have never gotten any repeatable results with Powerbelts. I recommend Shockwaves all day. I would order something else online if you want quality. It’s kind of like fram oil filters they have the biggest and best ad campaign so you see them everywhere but are the worst in quality.
You might want to check your owners manual I think it says something to the effect that 300g is the maximum allowable bullet weight in your CVA.[:@]
