I have a used Simmons Whitetail Expedition I picked up for a really great price. It is in excellent question other than a few ring marks. I would like to use it but I have a question regarding the adjustment value. Hopefully someone else out there has the same scope and can clue me in.
The model number is 800441 and is Phillipine made. It is 6x-18x with and adjustable objective. It has a duplex crosshair. The turrets are numbered in 2's (2,4,6,8,etc) with a hash mark on the turret between each 2's. It has the tall target type turrets that are marked from 0 to 22 plus one hash giving a total of 23 per complete turn. It has clicks on the 2's, on the hash marks (1's), and one click in between the 2's and hashes. This leaves me to believe that each click has a 1/2" of movement at 100 yards. What is odd to me is that it is a 6-18 powder scope and I have never seen a higher magnification scope with 1/2" adjustments. Most times it is 1/4 or even 1/8 adjustments. It appears to have a total of ~120 MOA of vertical adjustment if it is 1/2" clicks like I believe. There are no markings on the scope to indicate what the click value is and I can not find any information on the net regarding this particular model. I know I could bolt it on and just check but I figured I would ask before wasting the ammo. Thanks Dolomite |

Per your above description, you're correct, this design reads like a fairly common one that I'm thinking of. More importantly, it won't have the amount of internal adjustment you might think it does. To be on the safe side, I would assume that from the scope's mechanical center, you have 20 MOA to the right and to the left, 20 MOA down, and 20 MOA to 25 MOA up. I wouldn't push the internals past these numbers. Hope this helps. |

I wouldn't push the internals past these numbers. Hope this helps. I ran it all the way up, not tight but until I felt a slight difference, then back down. I was able to get over 4 complete turns from top to bottom. I will assume because of the 1/2 MOA adjustments I should be able to reasonably get 60+ MOA of adjustment if I install it on a 20 MOA base or at least 40 MOA without it providing nothing is seriously wrong. My only concern is the course adjustments at the longer ranges. I will definitely take it to 550 yards but will more than likely try my hand at some 1000 yard shots. I normally use a mildot scope with 1/4 MOA adjustments on the dial. It is a 223 bolt gun I am going to use. It will have a 7 twist barrel at a length of 26". The 20 MOA base is Ken Farrel and the stock is a Stockade PDS/T. Hopefully I have enough barrel to get enough velocity to get there. I will be using 80 grain for the 1000 and 69 grain for the 550 yard shots or at least that is the plan. Dolomite |

I have the same scope and it is 1/4 moa adjustments Odd, I guess they just use whatever numbers they want on the turrets then. Like I said mine is marked on the turret in 1's with a click between. Oh well, I guess I won't be using it then because it would make changes to confusing for me if I have to cut the numbers on the turrets in half. Dolomite ETA: Here are a few pictures of the turrets and the movements. There is a click between each mark. 
It doesn't make sense that it is 1/4" movement but you never know with scope makers. Maybe it is so you can keep track of your 1/4" clicks. That being said it would be way to confusing for me to use. I'll just stick with my MIL/MOA scope I have now that is correctly marked. |

Put the scope on your rifle. Go to a range with sufficient distance to shoot 100 or 200 yds. (or more if you're lucky enough to have a range where you can shoot that far). Load the rifle with the shells you intend to shoot in it and shoot it.
Shoot a nice group. Adjust the scope to move your group to the point of aim. See how many clicks it takes to move the POI to the POA. If its a 1/4 scope it'll take 4 clicks to move the group 1 inch at 100 yds. At 200 yds. it should move the group 2" for 4 clicks. Then shoot at the differenct ranges and find out how many clicks are required to have your POA and POI be the same as you move out to 200, 300 , 400 yds., etc. Write that down and keep it some place you can find it (some folks laminte it and tape it to their buttstock). Have fun. |

Have fun. I understand all that but I didn't really want to waste time and ammo if someone could verify 1/4 or 1/2 MOA adjustments without me having to hit the range. I will work out dope when I get the new barrel installed and run a few loads through it for accuracy, then across my chrony once I find a accurate load. I have a mildot scope I normally use to range as well as for hold over but was going to try my hand at making adjustments on the fly using the turrets instead of the reticle. BTW, I can shoot to 550 yards at a range that is free and open pretty much anytime, just show up and shoot. I also have access to a 1000+ yard personal range but I have to clear it with the owner before I go shoot there. I have a 50 yard range at home I use for sight in and pistol shooting. The problem I have is I have some serious injuries in my back from a helicopter crash a few years ago and trip to either of the long ranges puts me down for 3-4 days. Because of this I try to get everything setup before I go. I don't really want to waste time swapping scopes and such at the range. Thanks for all the info guys, I guess I will just have to shoot it to see. Worse case scenario I will just go back to what I am used to. Thanks again guys Dolomite |

As I stated in my earlier reply that scope is 1/4 moa adjustments. The numbers are so you can keep track of your comeups and windage adjustments. If you remove the center screw you can zero out the turrets. Thanks, to be honest that has to be the most idiotic setup. having 1/2 steps between numbers. It would have made more sense to have hash marks at every click. It is a nice scope for what I paid for it but unfortunately I am going to stick with something a bit easier on me. My other scope does have hash marks at ever tick then a number for each MOA of adjustment. It has 14 MOA per turn but I have been using the reticle for holdover as it is mildot. Thanks again, I appreciate it Dolomite |
