I handled a few of these at different times. Looked and felt well made. Seemed to work well. nice glass.
For me, when I was looking at them, I wondered why they did not put paralax adjustment on a long range scope. I also would like to have seen Target Knobs.
I think this scope would probably be right at home on a sub 500? 600? yd rig depending on how much correction you would need. I assume they were thinking of the guys that would buy it to put on their 300 win mag or 338 win mag and wanted to take shots out to 500 on their elk trip.
I liked the mount set up.
Bullets have well documented performance specifications.
Min Velocity info is available, and describes the performance floor of the bullet... DON'T allow yourself to reference F.P.E. as an accurate descriptor of killing power.. You are smarter than a copy editor, and you understand that you can determine maximum (reliable) effective range by comparing your drop chart to published bullet data....... And, dog-on-it, people like you!
