Adjusting Scope - Help

[Taxman003]

Ok, pardon the terminology but I hope you all will be able to understand.

I was sighting in Sunday (.308 Remington) and initially, at 50 m, I was 5 inches high. I"™m not sure what the trajectory should be at that distance, so I adjusted until I was 1 inch high and called it a day after that. I will be going back out for more practice and would like your advice.

My scope is a 2 ½X Redfield. The booklet says if you adjust one click it will make a difference of 1 inch at 100 yards and 2 inches at 200 yards. So, if I want to adjust at 50 yards (or metres "“ I know this is a longer distance) does that mean that 1 click is ½ inch at 50?

Thanks.

A single click is 1" at 100yards?That is the most coarse adjustments that I have ever heard of.Usually one click=1/4 inch and one division =1 inch at 100 yards.

if you are shooting a 150 gr. bullet you will be over 2" high at 100 yards.are you sure your adjustment is 1" per click at 100 yds.?

1/4" for on click at 100 yards will result in 2 clicks at 50 yrds for 1/4" . One click for 1" at 100 yrds is not common now days unless the scope that you have is designed for long, long range shooting. I find that hard to believe considering it is only a 2 power scope. Anything less that one hundred yards you divide 100 by that number and that is the number of clicks you must make to achieve 1" movement of point of impact.

Good shooting

Actually some long range target scopes are 1/8" per click at 100 yards.The further that you shoot the finer the adjustment that you need.

To answer your original question...Yes! If in fact one click equals one inch at 100 yards it will equal 1/2" at 50 yards. With adjustments that course it sounds as if you have an older Redfield scope.

How your 50 yard (meter) zero will effect your 100 yard zero will to a large extent be determined by how high above the bore line your line of sight is. (It is best to confirm your 100 yard zero by actually shooting at 100 yards!)

Good luck!

Thanks guys,

Yes it is one click for 1" at 100 yards. It is an old scope (I' m guessing from the late ' 70' s). I know I should be sighting in at 100 yards, but I' m on crutches and thought 50 would do.

I downloaded the ballistic tables last night and if sighted in at 100 yards, the 150 grain is off by 0.1 at 50 yards (so it' s negligible).

I am a real rookie at adjusting the scope and your answers have helped greatly. I have no idea why I' m so far off this year, but good thing I checked before I hit the bush. Back to the range for some additional work!

Heck-If the point of impact only varies 1/10th of an inch from 50 to 100, leave it an inch high and you can take it out past 100.

Yes, that' s called a ONE MINUTE-OF-ANGLE per click adjustment value.

There are a lot of scopes, particularly lower-powered ones, that have adjustments coarser than 1/4 MOA per click or dial graduation . AND, a lot of them, especially the " lower-priced" ones, that have coarser than 1/4 MOA adjustments, despite CLAIMING have them 1/4 MOA ones!! Take a look at the older Leupolds that have " friction" rather than " click" , adjustments. They have numbered dial graduations, and it is 1 MOA from one numbered line to the next. However, you can stop between lines for finer adjustments, if you want.
