Do you not know how to use the internet? google ballistics calculator and use one of the hundreds of calcs and then enter your data...

Hey franky, no need to be rude. I put that question up for people who know to give me advice. Not for assholes to tell me to do things that got me here in the first place.

What length barrel? Box ammo or handload? Know the velocity?

Plug the data in here and it will be very close.

I use Strelok for Android to run my calcs..... if you got a smartphone....

I run a straight-from-the-factory Barrett 98B with a 20" barrel. I reload lapua brass with lapua 300 grain HP and 85 grains of vihtavuori. I can't remember if I figured 2400 fps or 2500. Ill get back to you on that. I'm also down in south Florida where the temp is the same as the humidity (90ish) and the elevation is lower than your shoe size. You guys are super helpful btw.

This should get you started. Based on a 2450mv, sea level, 85f, 80% humidity, and a g7 BC of .389(the 419 BC on the box didn't match up with my trajectories at all, and .389 is what resulted from a range test by several of the guys on this site during a gunsite XLR shoot/bullet test.

Cool. Thanks. Sweet rifle too. Negative points on the bud light though.

It's a proven fact: you can't drink all day if you don't start in the morning.
