Does my 451 have to small of a cam?

M40A2 for a 1500yrd. Center shot, call me , that's what USMC. Trained me to be a EXPERT at.

Only 1500yds? What do you need glasses??

LOl... Sorry, I had to. It's just like setting up and calculating windage. You just take it one thing at a time, and get it right for the environment you're in.

Thanks for your service BTW.
