Re: need advice on load work up for 338

Went shooting yesterday.. i loaded up 91 and 91.5 at different seating depths and shot. I didnt shoot any half moa at 400 yards but the wind was blowing from 2 oclock position.. some groups were moa and some were 3/4 moa. I think iam just gona load 91.5. 25 thousands off lands as it was the best a couple weeks ago.... now i just gona need some advice on how to do trajectory validation. Could some of u guys tell me how u do this ..Do i just need to shoot at every 100 yards and mark down my dope for it. Any advice u can give me would be appreciated.

you can shoot every 100 yards and collect that data, and play with your velocity input on your ballistic program to match the data you have recorded. The shooter app for smartphones, you can get your ballistic chart hit settings and go to trajectory validation, input 5 distances along with the corresponding MOA correction for each distance and it will adjust your ballistics chart for you.

Can you give some step by step instructions for this? I can't seem to find it.

Thanks

Re: need advice on load work up for 338

Once you select your rifle and ammo, and put in your conditions, then hit calculate.
From there you can select solution,table, or graph.
Select table: once the table comes up, I know on iPhone there is a tab on the top right, not sure about android, hit that button on the top right on an iPhone or menu type button on android I'm guessing:
Once you hit that a menu should pop up allowing you to select between: show lead, email table, or velocity calibration.
Obviously hit velocity calibration: and that's where you should be able to input your information I mentioned, hit calculate and it will give you an adjusted velocity.
