There are 2 options. If you have a newer Leupold scope thats not a CDS scope a scope thats 5 years or newer(talking to the Leupold rep), you just box it up and ship it to them in Beaverton Oregon. You will send them all the info I stated above earlier. It cost me about $20.00 to ship my scope in cluding insurance, plus the $150.00 for them to make the engraved dial Takes about 2 weeks once they receive your scope. Don't send any money, just your shipping and contact info along with the scope. Leupold will call you for your dedit/debit card info. If you have purchased a CDS scope you call them with all your info and they will engrave the dial and mail that out for you to install (you wont be shipping your scope). Installlation is a snap, just 3 small set screw on the dial. Once you have converted a non CDS scope over, you wont have to ship it off again, if you choose to have different loads for your rifle and another engraved dial is like $65.00.
You only get 1 revolution on the dial since its engraved with yardage marks. Because we are talking about MOA, you will have fewer marks between 200-300 yards, and alot more between 600-700 yards. My sons 308 has marks out to 575, my 300 win Mag has marks out to 800, both zeroed at 200. If I did a 100 yard zero, my scopes will not have settings on the dial out as far as they are now. I have been around quite a few people with different zeroing points on their dials. A 100 yard zero your able to really zero your rifles vertical trajectory, but your gonna lose some distance on the dial setting. It will become your preference.
Bragabit sorry to hear about the problems your having, they did mess up on your scope, I am wondering if your info was conveyed over the phone. That too bad, I could not be happier.
