She weighs around 16 lbs as is, 6.5 Creedmoor with a Vortes Gen 2 razor. I have been shooting at an 800 yard range but plan to shoot further next year. Guessing windage is something new to me and my son also shoots. It is a blast. I am waiting on a suppressor for it.
I'm right there with you stretching out the distance. It's all about the wind at these distances. If you have not purchased a kestrel yet check out the weather flow wind meters. You plug them into your smart phone. If I go out for a walk or am going to be outside at all I'll take it with me. I'll observe wind conditions and then run the wi d app to see if I'm close just to get some practice. It's a lot harder then folks give it credit for
We have an 800 yard range in Oak Ridge, TN. I visited this one while in AZ recently. Did not shoot. Just walked around. They were getting ready for a SW competition.
