I just picked up a g seven by gunwerks. Tried it out on bigger objects such as buildings, trucks and treelines and it ranged out to 2316 yards. I have used it at the range twice and picked up targets out to 1477. I still have a lot of testing to do with it but it looks good so far. Entered 2 rifles in the ballistics program and it mirrored my kestrel
dial up so far. Shot it out to 900 working it from 600 to 900 with both rifles on 2 different days with very good results.
