Sighting my scope
 

Hi guys, It's almost gun season here and I'm trying to sight the scope on my 30-30.
Right now its pretty accurate but shoots a little high and to the left.
How can I fix this?

How much is "...A little high and to the left"? And at what range are we talking about? Have you tried adjusting the "dope" of your scope?

I always do all of my sight-in work off of a bench to eliminate as much of the human error as possible. Since I don't have a boresighter I start sighting in a new scope by shooting at close range (25-30 yards) at a large target (2'x2' at least) to make sure I'll hit paper. For the first few shots I'll use a "called shot" method for determining whether the shot was off due to the scope or myself, adjusting the scope after every shot until point of inpact is within 3 or 4" of bullseye. Then I move the target to my intended zero range (usually 100 yards) and start shooting 3 round groups. If I get a flyer I'll just shoot a fourth shot to make sure. After each group I make 1/2 value adjustments to the scope until I'm satisfied with the point-of-aim/point-of-impact. By 1/2 value adjustments I mean that if the center of the group is 4" high and 3" left at 100 yards, I'll adjust the scope down 2" and right 1.5" and shoot again. This is to make sure I'm not overcorrecting and chasing the dope around all day.

Good luck,

Mike

Driftrider's right, basically down and to the right is required. Most scopes are 1/4" per click at 100, but just check and make sure when you remove the scope cap covers. Also like he mentioned until you know how your scope tracks adjustments, go with 1/2 the required adjustment. It also a good idea to shoot 2 shots before re-adjusting, scopes can sometime need the recoil to settle in (Can tap the adjustment knobs with a screwdriver or small rubber hammer to help this process, if it is required)
