RE: tips 4 sighting in a new rifle?
I use 130gr. for my .270. First I would bore sight it an then start at 25 yards and then fine tune it for 100 yards. One good thing to do before you shoot is clean the barrel real good before shooting,then while at the range,take it slow and make sure things don't get hot and run a dry patch after every 2-3 shots! This will help in the "break-in" of the barrel...

Might be info you already know? The bullet weights and brands should not be mixed as each can shoot differntly. I shot 3 shot groups. Starting at 25 yards is good idea and move out to 100 yards like mentioned above. Everyone sights in differntly at the 100 or 200yard zero. I also "tap" the scope lightly after eachscope adjustmentto make sure the reticles move if they happen to"stick" internallywhen adjusting the scope I personally sight in 3 inches high at 100, not everyone agrees with this but works great for me.

I'd pick a grain size you intend to use with the 270win. Start at 25 yards, adjust so you acheive a grouping approx -1"(below) the bull and then move to 100 yards for fine tuning/adjustments for zero. Most of my rifles sit at +2" at 100, that allows me to have a MPB of 300 yards (without hold over). Though it dependsentirely on your situation,say a 200 yard shot is the max that you'd see no real need to site in for further ranges.
I assumed that your scope was boresighted when mounted but an easy test is to place an orange dot on your target at 25 yards, then remove your bolt and place it in a solid rest position. By looking through your bore line up the centre of the bore with the dot and without moving the rifle raise your head to see if the crosshairs are approx. in the same position. If not you can adjust them to match what you see through the bore to acheive bore sighting. Then fire groups/fine tune as per normal. (a second pair of hands is helpful for this procedure if you don't have a gun vise or rest that helps stabilize the rifle easily).
Good Luck and enjoy
