Most of what I heard is great, but bear in mind that unless you rifle meets certain criteria, like barrel length and grainage of bulliet. In other words like .30-06 Springfield 168gr bulliet, 24" barrel.
If you have a compact 16" barreled, shooting 147gr bullet, you out of luck. For the cams used Bulliet Drop Compensator are very set up specific.
But their still worth checking out. For if your rifle meets the criteria, and you'll have a dam good scope that once zeroed hardly requires thinking to use.
