Hello everyone, I've just joined and can't wait to learn. I'm a retired emergency room nurse. I have been shooting since a kid, but haven't shot for distances since the Marine Corp (1969). First rifle for distance was an AR30 in 338 lapua, bought the gun before pricing ammo. It was quickly sold. Currently have sig ssg3000 and I have a couple questions that I will post and look forward to y'alls expertise.
