I have lost the covers to my windage and elevation adjustments on my Simmons scope. Where can I purchase new ones?

Your scope has 5 adjustments:
1. Eye piece focus - used to focus on the reticle.
2. windage adjustment - should be on the R side of the scope, adjusts lateral impact point.
3. Vertical adjustment - the top turret. Adjusts vertical point of impact.
4. Power ring - adjusts the magnification of the scope.
5. AO ring - Parralax adjustment - used to focus the scope at specific distances. Most markings are not exact, you should set it at the range you are shooting and fine tune focus when you look through the scope.

One of the things about bore sighting is there is no shock to the scope. They are meant to have some shock that goes along with an adjustment. Try smaller adjustments and tap the tube of the scope with a screw driver handle after every adjustment. Not so hard you dent it but hard enough to get stuff moving. Hope this Helps FixYa up.

Yes there is a screw on cap covering the adjustments. Here is one of there general manuals on the link below.

The adj knobs on there are for windage on the right and elevation on the top, if they are not covered, they are turret knobs for target shooting, not for hunting. The focus knob is the rear lens, it spins in and out to fit your eyesight. It usually focus on the crosshairs and the distance for most shooters, some will not be able to get it right because of their eyes. 98% will. Hope this helps.

I don't have this particular model. Chances are, those are not "knobs" but caps. Remove the caps as you would remove the caps from a pill bottle. Underneath, you should find the adjustment dials for windage and elevation,

Is that the "Prairie Master"? I think Simmons is pretty uniform in that range of scopes--elevation adjustment should be the top dial and windage is on the side. The zoom locking ring should be in front of the eyepiece, with the zoom ring just forward of that.

if you cannot adjust it using the windage and elevation screws, you have a defective scope. Most scopes have a warrenty. If you purchased it new,, the store from where you purchased it should replace it.

Sounds like you want to "re-sight" in your rifle. Make sure mounts are okay and tight. Look down barrel and then thru scope and eyeball windage and elevation adjustments so the scope seems to be fairly in line.

Clean barrel if it needs it.

For basic sight in, start at 25 yards with a large(3 to 4 feet) cardboard or wood backdrop around target (bullseye). Fire at target. Once done, look through scope and position rifle such that the shot mark you created is dead zero. Hold rifle very steady and you or buddy move windage and elevation adjustments until scope moves dead zero back toward original target (bullseye). Fine tune from there. Air cool rifle between rounds. Once dead eye, fire another round or two to check grouping. Check your ballistics (sometimes on ammo box) to see how height at 25 yards affects your desired dead on target (100 yards, 150 yards, 250 yards etc.). Adjust accordingly. Example: you may need to sight in at an inch high at 25 yards, depending on your dead on target distance..

Always remove sling from barrel when sighting in.

Try to sight in at similar temperature as you intended shooting temperatures, if possible.

If not black powder, avoid cleaning barrel between sight in and hunt/competition unless you note bad buildup inside.

If you change ammo, understand that that may affect performance. Once a preferred ammo is found, some even try to buy a decent quantity with the same lot number on the boxes if storage allows for such.

There is no manual for elevation and windage adjustments. (at least not one that comes with your scope; all your scopes manual will say is whether its FFP or SFP (First Focal Plane or Second Focal Plane, the scale used on your scope for mil dots)(you can get this info by finding a store that sells this scope and asking a sales rep)

To adjust for elevation and windage you have to take into account the daily factors (unless your shooting in the same indoor environmental controlled shooting range each day you SNOB! jk

The formula takes alot of variables into account and is known as Exterior Ballistics

!) Environmental Factors - First thing you account for.

A) Elevation from sea level plays a large part into your environmental adjustments. Your elevation from sea level determines largely the Barometirc Pressure but it also varies slightly with Temp and Humidity (Major Factor)

B) Temperature - The temperature can affect the density of the air. The hotter it is the thinner it is and therefore less resistance and a higher bullet trajectory (Minor Factor)

C) Humidity - This again will affect the densify of the air infront of your bullet (Minor Factor)

D) Barometric Pressure - The other large factor in air density this is the base stat that the others modify

These all combined create a ratio that you apply to standard MOA (windage and elevation adjustments) to obtain the shooting information for that particular environment)



2) Bullet Factors (Listed on the Box you buy) - There are a few bullet factors to take into account.

A) Speed - the bullets feet per second can vary as much or more than 500 feet per second with the
same caliber ammunition.
B) Grain - The Grain of an ammunition is a measure fo its "Sectional Density" or weight to volume
ratio
C) Ballistic Co Efficient - This number is the measure of the bullets ability to maintain its speed
during flight. This also varies from Grain to Grain


These factors are complex and a pain for the best of shooters to determine. adding to that confusion. there are many ways to determine a bullets ballistics coefficient and each one gets a different number. In this case bullet data is best retieved from the manufactuerers box and take their word for it.

3) Lastly you account for shot factors.

A) Range - by referencing your standard elevation MOA adjustments and mutliplying by the ratio for environment the Elevation MOA is achieved.


B) Windage - Windage is done in inches per mile per hour then is multiplied by the Mph of the wind.
In order to be precise the windage is done in inches instead of MOA. it needs to be converted heres and example.

You Ballistics Cheat Sheet for the day says the windage at 900 yards is 5.2 Inches per mph of wind.
you apply the ratio for your environment .90 (all example numbers. this number would represent a shooting environment with an air density lower than standard/ the cheat sheet's known MOA adjustments). the 5.2 inches is multiplied by .9to acheive 4.68?? idk the point is you mulitply that by the wind of 10 mph to achieve a total of 46.8" of wind drift to the target.

now for the conversion to MOA. 1 MOA is eqaul to 1.047" per 100 yards. meaning for every 1 moa you adjust the bullet will move 1.047" per 100 yards (our target is 900 yards; meaning that each MOA for this target is 9*1.047" = 9.423" per MOA adjustment. so take that number and divide our total wind drift by it. ie 46.8 / 9.423 = MOA Windage Change of 4.9665... now you need to know whethere your scope is 1/4 minute clicks or 1/8 minutes (how many spaces between large numbers?) you would adjust to 5 MOA for a 1/4 minutes scope equaling 20 clicks on an 1/8th minute scope it would be 40 clicks.

This is the math of shooting. to learn how go to
WWW.shooterready.com they are an excellent sight to get the math down WITHOUT wasting ammo. Once you have the math you an transfer it to your gun. waste a few rounds checking it out and youll be hitting targets @ 1800 yards in no time

I like to take the simple way after i learned how to do the hard way

There is software tha will do the exterior calcualtions for you.

if your interested i use Sierra Infinity V6 Ballistics Software

I'm not sure how this got posted in the car audio section...

 

If the scope was manufactured by a well established company, you should be able to get a new cap from them.

 

If you cannot locate the manufacturer, you can move the other cap to the windage adjustment to set the windage. Then when you're finished, move the cap back to the elevation adjustment.

 

Even if you use it for a shooting discipline that requires constant adjustment, it's unlikely that you'll need to use the windage adjustment for anything other than setting the zero.
