Working on putting together my first mid-long range rifle and was wondering how you guys make sure your scope is as level as possible. I typically use a plumb line and hang it from something 25 feet away and make sure my vertical post is true to the plumb line. This has always worked for me in the past but wondering if there is a more precise way to do it. My rifle is a Bergara Premier Approach in 6.5 PRC and I am going to be putting a Zeiss Conquest V4 4-16X44 scope on it. Just trying to get my feet wet at this point and become proficient out to 600 yards or so for now. Thanks!
