    Since I'll be sighting in a new rifle I thought it would be a good time to get others input on the subject. I'll be working with a Rem.700 ADL in 270. My scope is a Buckmaster Nikon 3x9x40 ( I know there are better scopes out there.) I'm using Leopold Rail and rings. Remingtons core-lok in 130 Gr is what I'm hoping to be able to use as it is the most available to me. Most of my hunting offers shots in the 40 to 80 yd. range , with sometimes a 200 yd shot. I'll be using a bench rest. I've sighted in several rifles to my satisfaction but want to hear what others may have to say. Thanks in advance.

    At those ranges I'd try sighting in dead on at 100yds, then set up a target at 40yds & 80yds and see where you hit. Should be within about an inch or so at those ranges depending on the highth of your scope above the center of your bore (ring & base highth,etc.). Then set up a target at 200yds and see where you hit for reference. -- In wide open spaces where shots are often long, I normally sight in a 270 around 1 3/4" - 2.0" high with 130s. This puts it about 6"-6.5" low at 300yds depending on the load,bullet,etc. with the top of its arc between 140-160yds. -- Good luck..........[8D]

    What Temblor said is good information, I too would sight in for dead on at 100yards. First off though make sure all screws are snug on the gun/stock, scope and mounts. Then what I do is set the gun up somewhere stable with sandbags and sight down the bore and let it rest steady looking down the bore at an object, (fence post, target etc.) and adjust your crosshairs to match what you are looking at, yeah you could go someplace and have them bore sight it for ya but this is more fun and puts you on the paper at 100yards too. I always set up on my range at 100yards, fire 3 shots and look it over careful and make your adjustment, then repeat until you got it right.

    All of what ya'll say sounds like your right on to me. I like the bore sighting method that was mentioned , I never thought of that. What do ya'll do about lok-tite on the scope? I know I will lok-tite my rail down, but havn't decided on my rings. Also the only rail I could get my hands on at this time in a leupold had a windage adjustment on the rail. I don't know if I like that or not. I never consider adjusting my scope for that. .heck . .I very seldom see a deer here if the wind is blowing much , and if I do I just go a hair one way or the other. It just looks like something else to work loose.

    you do not need to use thread lock on the rings, not on a .270 Good luck.

    Don't worry about those windage screws on your Leupold bases I have those bases on 10 or more of my rifles and have never had one bad experience, don't use locktite on your rings, honestly I don't use it on bases either but some do. Good luck and have fun!

    If you do use any locktite make sure it is the BLUE color that is easy to break free later. Do not use the green stuff as you will find yourself using a propane torch or other method to get it loose someday. Nothing wrong with the windage adjustable base.It's plenty reliable and occasionally you'll find you can't get your scope centered with one click in either direction but can move the rear of the scope over to accomodate the dead spot.....good luck again....[8D]
