    Adjusting for parallax in a scope. Anybody done it?

    I ran across something I had never heard of, at least not doing this yourself. I always thought that you had to send your scope back to the factory to adjust the parallax. I have used centerfire scopes on rimfires before I knew any better. Most regular rifle scopes are set parallax free at 100 or 150 yards. So on another forum a guy was going to buy a new Leupold Freedom and put it on his rimfire. I checked and that particular scope was set for 150 yard parallax free. He was looking for input so I told him that fact. I was informed that he could adjust the parallax himself, to what ever he wanted. News to me. I haven't tried it yet. The scope has to have a removable front ring on the objective end. Remove that and there is a nut inside that moves the front lens. He told me he could adjust it to 50 yards, then back to 100 or 150 later if he wanted. I went to youtube and there is an example of a guy doing that but he doesn't explain it very well, but adjusts it down to 10 yards.

    Oh well, I always said we can learn something new everyday. I may have missed a few days but am always willing to learn, now if I can just remember all of it, HA

    I use 4X32 and 1-4X24 scopes on rimfire rifles all the time for squirrel hunting.
    Not sure what the parrilax is set for...
    But if I can hit a squirrel in the head at 30-40 yards I figure it don't matter.

    I have heard of what you are talking about, but I have never tried it.
    I figure sure as anything I'll mess my scope up.
    The best way to tell if you have a parrilax issue is to set up the rifle
    looking thru the scope at a given distance you wish to shoot, and
    slightly move your head side to side and see if the crosshairs move.
    But, I only worry about it if my gun won't group...
    And then, if that happens and I determine it is a scope/parrilax issue..
    I try another scope.

    You're right about the parallax issue of the crosshairs moving. I have rimfire scopes or those with adjustable objective ends now. It just struck me that I hadn't heard about this before, but what do I know!!!!

    The only thing I knew of adjustable parallax is on scopes that have the adjustment for that. I've used rifle scopes on rimfires many times and it hasn't been an issue for me and I shoot them from 25-100 yards. I have a Savage 17HMR I bought new last year and haven't shot it yet with the scope I ended up putting on it, which is a Nikon M-223 4x12. I got this scope in a package deal of AR parts a few years ago and never used it for anything. It was still NIB. When I needed a scope for the Savage 17HMR, I figured why not try it? It's a bit large on that rifle but if it hits what I'm shooting at, it will stay on it.

    I think you will cause a 'leak' of the inert gas out of the scope leading eventually to fogging problems. I was thinking of getting a Vortex Crossfire 1-4*32 for a crossbow, Vortex Canada said they could adjust parallax from 100 down to 40 and purge the scope with inert gas for about $75.

    I use a Vortex Crossfire II 4-12*40 AO on my Savage MK II FV .22. The adjustable objective allows you to use maximum magnification and focus at any range over 10 yards. With high magnification and parallax adjustment I get very little eye fatigue while target shooting.



    Great rig for spending the day at the range.

    This is news to me as well. I know the VX-Freedom is a new model but Leupold does not advertise being able to adjust parallax on these scopes, at least not by the end user. Seems like a good way to possibly void their famous lifetime guarantee to me.

    I've tried adjusting the parallax in a scope. Apparently you can change it by turning the ring that holds the front lens in place in or out but mine was too tight & looks like a special tool is needed.

    This is the forward adjustment ...

    It is interesting and time consuming.

    Where I ran across this was on Rimfire Central. One guy was buying a new Leupold and it was set at 150 parallax. Another guy told him he adjusted some from 100 to 50, and if he wanted to put it back to 100 for use on a center fire, he would. Surprised me as I thought it had to go back to the factory. They are taking the objective ring off and accessing the nut inside. They all look like it would take a spanner wrench, but with the nut off they were using a metal scale. All new to me and I haven't tried one yet.
