I have several made in Japan Bushnell scopes. A 2x7x32, a couple of 3x9x32, a 6x32, and my favorite a scopremaster 4x32 that only made for a year or so in the mid 50s and sold for about $50 back then. All of the Japanese Bushnells that I have have Bausch and Lomb lenses and all are very good scopes.
Oustanding info. I used this knowledge to correct a Weaver V-22A objective lens on a used scope that had been turned in all the way. The rings were loose, so it just required ALOT of adjustment. Now it shoots ragged holes at 25 yards on a Marlin Ga-22. Thank You!
Remington 788 is a great gun. I got one years ago but it’s in 308 Win. Very accurate!! I have several Tasco scopes. Tasco was here in Miami about 10 miles away. I would get scopes that had problems for free and Tasco would fix them up and sometimes they would just replace it with a new one. That was in the 70s and 80s. Don’t know where they are now. Good to see you back and good luck on the 788 hunt. Richard
Now I understand why I was unable to achieve acceptable accuracy with my Ruger 10/22 Competition when paired with a Nikon scope that was meant for a centerfire rifle. The parallax was all wrong. After changing to a Nikon rimfire scope the accuracy improved significantly. Thanks for a very informative video.
The parallax issue is why I almost always put a scope with a side parallax or adjustable objective on my rimfires. Most folks don't even think about this issue, but it is more important on rimfires than most centerfires. I have set up a Remington 581 with a centerfire vari-II 2-7x just like you show here.
Great video addressing scope parallax when using high power riflescopes on .22’s. Found it interesting using the acetone, so after doing so you did mention any need to reapply anything to reseal the objective rings.
Thanks a lot for your recent video on adjusting parallax in rifle scopes! I have a Bushel banner 3x9-32 and a Tasco 3x9-32 laying in a drawer that I took off of big game rifles but the parallax was too bad for accurate use on my .22 rifles. Both are old Japanese made so I gave it a try right away this morning. Both worked out great with no parallax and good focus at 35-50 yards which I shoot regularly! Now I just have to decide which of my .22’s will get the opportunity to try them out! 😁 Thanks again for all your .22 series videos!
Yesterday I adjusted another scope for parallax as you showed. A Simmons .22 mag 3x9-32 that was totally useless because I could never focus both the crosshairs and target at the same time… it was either one or the other. I had to turn the lens around 5 full turns to bring it into focus with no parallax. To my amazement, now everything is in focus at .22lr ranges. I put this scope on a Steven’s model 36 single shot that I cut off the barrel and stock to make a boy’s rifle years ago. Works great! Thank you so much for sharing your knowledge about changing parallax in these scopes! You helped me take JUNK and make a useful .22 scope out of it!
Mount scope uncomfortably forward. Seeing the black around the edges has the effect of correcting parallax when the x is centered. This is a valuable hack when going to longer shots out of parallax settings. Grey squirrels move too much for any adjustments. My favorite scope is a 2x7 VX 2 compact on ULA 22LR
@@WalnutandSteel I was pleasantly surprised at how well it turned out. I recently obtained a very nice 582, and I featured it and this 581 in a video. If I had to admit it, the 581 is my favorite .22 rimfire rifle model. I now own 5 of them, mostly because I admire the design, and how well the action was made.
@@CumberlandOutdoorsman and @WalnutandSteel it is good to see that my two favorite video producers have a link, the old 581. Tom got me hooked on the 581, I now own four and three 582’s.
Cumberland Outdoors, I have been around rifle scopes since the 1960’s. I have never studied then but, I do know about parallax and just bought the proper one for the proper distances I would be shooting. I never knew the scope could be adjusted by this method for parallax. As old as I am I still learn things. Thank you.
Thanks again for another interesting and relevant .22 rifle video; maybe the most relevant to me so far. What is your procedure for cleaning the .22 rifle between ammo brands?
I mounted a shotgun scope on a Ruger ten-twenty two. For one thing those are supposed to be parallax free at 50 yards rather than the usual 100. Plus the tube is straight so really low mounted and variable power 1.75-5X, good enough for pretty much any rimfire work. The larger rear of the scope with the zoom hangs over the receiver roll off so has plenty of clearance. Works for me.
@@CumberlandOutdoorsman No kidding the prices on Remington 788 and 660 rifles has gone way up around the time when the scamdemic was rolled out, but so has the prices on many firearms by design.
Frank Bannan. Greetings from 'down under' Tom. Tell me, when you say 'screw' the lense, is the lense threaded or screwed into the thread of the bell of the scope housing or what holds it in place when the locking ring is re-tightened, and do I need to apply some new glue. Roughly how many turns and which way to change it from 150yd to 50yd?
Sorry for the late reply. To answer your questions I would really need to see the scope you have in person. However the rings that hold the lenses in place are indeed threaded into the bell of the scope.If you are shooting a .22, there is not enough recoil to worry about using any glue. The locking ring will hold things in place. In my Bushnell scope, I screwed it about 3 full turns to get most of the erratic movement out. You really need to play with it somewhat to get your optimum setting.
Hi mate, Gordon from Australia. After you dissolved the glue around the lense ring , have you had any fogging issues? , I was led to believe that a lot of scopes are filled with dry nitrogen to prevent fogging in extreme temperature or humidity. Does this release the gas? Thankyou for a very informative video.
Great question. Here in Tennessee we have plenty of humidity along with temperature changes that are extreme in most years. I have not noticed any fogging issues with my scopes. I never fully remove the lenses, so I think the nitrogen does not escape.
Awesome and thank you for sharing. Is acetone the best solvent to use? Will isopropyl alcohol work? Do the solvents have any negative effect on the lens coatings?
I have never used alcohol, but I don't think it would be very effective. Acetone has never damaged my lenses or their coatings. After it evaporates the lens still has the same bluish or reddish coating it had before I started.
Some folks shorten the trigger spring a coil or two, but personally I wouldn't. Take the trigger assembly down, clean and polish the sear engagement. Check out my video on how to service 580 series triggers.
Great question. I would first of all make sure they need to be adjusted. If you are concerned about the acetone getting into the scope tube, then don't use as much of it. Personally, I have never had a problem with it leaking inwards. If it should ever get past the objective ring threads, then your scope is already leaking out nitrogen. Acetone evaporates very quickly and it shouldn't leave any residue.
Interesting video I've been a fan of the Remington 581 since I my dad bought one for me in 1970. In pouring acetone on your lens, did it remove any of the lens coatings? Did you reseal the lens that you loosened and turned?
Hey Tom! Thank you for the great content as always you are very detailed. I just viewed a episode by Hickok45 and he was talking about some UA-cam restrictions on gun sponsorship. Will this affect your channel? I hope not because I really have enjoyed all of your videos and everything you do on your channel. Please reply back and let me know. Stephen Milligan from Georgetown Kentucky
As far as I can tell, I have only had one video that got limited monetization. I don't understand why, because all I did was restore and refinish an old Marlin 60 in that video. Perhaps it was because I filled two holes in the stock and they somehow considered that as "altering" the gun??????
You must turn the objective lens outward to correct parallax to a closer target, not inward. Look at your AO scope to see that. I believe you got that backwards.. ?
Seems to me that would also break the moisture shield and it would fog up with sharp temp changes ,just wondering if you checked on that? Love your vids by the way, watching for the home of the bluenose ‘
This is absolutely something you should not do, a rimfire scope can be bought for less than $50 and if you look around you can find a used one for half that price certainly preferable to doing what you suggest
Yep, this is a good way to lose your nitrogen gas fill. I just learned to always center my crosshair in the vision field. But this should keep the scope warranty people guessing at the factory. 😆
I have done this on older scopes that I wanted to mount on my rimfires. Never ever had a problem. Yes, you can buy one of those Chinese made so called rimfire scopes, but as I stated in this video, you can correct the parallax on a good quality Japanese made scope without a hitch. No nitrogen loss, no damage to the lens coating in all the ones I have on my rimfires, and when I get done with one, it tightens up my groups, and you can't tell anything has ever been done to the scope. I have never had one of these scopes fog up due to nitrogen loss, even in the humid conditions we have here in Tennessee. That being said, if you don't feel comfortable doing this........then don't.
Maybe, but the main difference is that Yugos are practically non-existent, meanwhile these older Bushnell's and Tasco scopes are still around and going strong.
Tom, the .22LR has been a big part of my life where shooting and hunting is concerned. I've enjoyed all your .22 videos. Thanks for that!
Thanks.
Great video with valuable information. Parallax is a big deal and most casual shooters don't know it exists.
It should be basic knowledge,one of the first things you learn.

A 2x7x32, a couple of 3x9x32, a 6x32, and my favorite a scopremaster 4x32 that only made for a year or so in the mid 50s and sold for about $50 back then. All of the Japanese Bushnells that I have have Bausch and Lomb lenses and all are very good scopes.
Looks like you are just as aware of the quality of these scopes as I am. Bausch & Lomb optics are high quality, and they have a great reputation.

How does the acetone affect the coatings?
How does those eleys HP's shoot out of most of your guns?
Will that work on varible power scopes?
Great question. To answer your question....yes it will, but certain models are harder to manipulate. It all depends on the adhesive they used.
You must turn the objective lens outward to correct parallax to a closer target, not inward.
Look at your AO scope to see that.
I believe you got that backwards..
?
I hate to think what the acetone is doing to the lens coatings?
I did the same thing, but had no issues. After the lens dried, it still had the same bluish hue that was on it before.
I understand, but would that not affect moisture resistance of the scope?
Great question. I have done this on several scopes, and it never presented a problem.
Seems to me that would also break the moisture shield and it would fog up with sharp temp changes ,just wondering if you checked on that? Love your vids by the way, watching for the home of the bluenose ‘
👍👍
Seems to me that wouldn’t do the coating on the lens any good! Acetone is a very strong chemical but I’m no chemist.Good video thou
Good point, and well worth considering. On the ones I have adjusted, I did not notice any damage to the lens coating.
The biggest danger would be if it came in contact with a rubber o-ring. If so, it will fail allowing moisture into the scope.
Why not just buy a rimfire scope?
This is absolutely something you should not do, a rimfire scope can be bought for less than $50 and if you look around you can find a used one for half that price certainly preferable to doing what you suggest
