Re: Federal match 175 gr .308
I don't know how serious you are wanting to be, but if it were me, I wouldn't want to trust my dope past 500 yards to guessing at my muzzle velocity. But that is just me. I think the best way to go is to run some over a chronograph and then run some numbers in a ballistic calculator. Even then, when you get out at distance, things like Density Altitude are going to change, so you will either need to have multiple cards or a field useable ballistic program...
I will do a search there was someone selling drop cards here, I think they were adjustable for velocity and DA..
