Got a newb optics question

Very good question, ...er... after TRYING to explane the MOA and the powers of magnification I made it more confuseing than it was in the first place. Just woke up and I am not a morning persion. il leave it to someone else or when I wake up.

Something that is fairly easy to explane.
eye relief is how far you keep your eye away from the scope. You wouldent want a low eye relief scope on a 338 Lupa Mag, otherwise youd come out with a nice black eye and everyone pointing at you.( Yes, this happes alot at .50 cal ranges )

Aha! (Big props to Janq and Jamz for4 the Midway link)

3-9x40 is scope Magnification and Objective lense size. In this case the scope would be 3-9x magnification with a 40mm objective lense.

Eye relief is how far behind a scope you need to have your eye for a good view. Rifle scopes, telescopes, binoculars and microscopes work on parralax of light to magnify. If your eye was too close or far away you would see the image upside down. Depending on the quality of your lense and how the scope wil be used denotes what you need for eye relief.

MOA:

Definition for "minute of angle":
(MOA) A measurement described as a 1/60th of one degree of angle, such that at 100 yards, one MOA is equal to approximately 1.05 inches. MOA is a widely used means of determining accuracy and measuring group sizes; a firearm that can consistently fire groups of 1 MOA or less would generally be considered quite accurate. On some military rifle sights, the distance between two lines (clicks) on the rear sight is equal to four MOA.

They pretty much covered the magnification 3x-9x, objective lense 40 and eye relief distance from scope to eye. The other thing that in my opinion you want to look for is waterproof/ non-fogging lenses. Hot, cold rain and humidity can all cause the glass to fog. Cheap untreated glass will fog, it's just they way it is. When it comes to scopes buy the best you can afford.

Thanks guys, that really cleared it up.

If 1 MOA is 1.05" at 100 yards, what is it at 50 yards? .525" or some other #?

Cool. Now I know what I have to work towards with my 10/22.

aspirations of .22lr at 600 yards?!?

lol, I had wondered what that post was about to, was not going to say anything...

Gonna need a periscope to get that much elevation.

yes, I have new rocket assisted .22 shells and need a goal. 6" seems attainable.

Seriously, I am playing at 50 yards right now, until I finish clearing the 100 yard range.

I think it'll be like that old school vid game Artillery/Scorched Earth LOL.

no way! i thought i was the only one with those...

oh btw, if you're still looking for a scope, i highly recommend the simmons 44mag for the 10/22.

Sure, just recommend I spend more money on it. My old Bushnell seems to work, but every time I improve things I realize how poor it was before. So new optics will come and I will ask how I managed with the Bushnell.

what good is a 10/22 unless you mod the crap out of it?

There is plinking fun to be had in a stock 10/22. More fun when you add the barrel and a new stock (which I just did recently). Have to decide what next, looking for improving accuracy not looks.

How accurate is it now? What accuracy are you looking for? What barrel and stock ?
