Keith, I want to thank you for this video. I've been shooting long range rifles for 15+ years including 2000 plus yard ELR. I've developed loads for all of my stuff and helped many other people along the way. I have NEVER heard this explanation of scope mechanics. Mind blown. This certainly explains some issues I've encountered over the years with scope adjustments not seeming to respond correctly, especially when trying to zero. Thanks for taking the time to make this video and I appreciate the knowledge you bring!
@@perchowski3021 I have done some machining. I was also a heavy truck tech and welder for 17 years. I understand backlash well. I just never thought about it from a scope turret perspective. Understanding how the turrets work made all the difference
Just found your channel. I'm a wannabe; I've done some machining so all this makes perfect sense to me. Thanks very much for your effort. I'm going to share this around; I agree with others-- everyone who uses a scope needs to see this. Two thumbs way up!
......been doing that for 40 years, EXCEPT, I didn't take into consideration the VERY valid point you made about the importance of the directions with spring-tension on the erector tube. Thanks fer sharing !!
This is the same approach used to adjust an artillery director (think surveyor transit) and guarantee repeatable results. We were taught to "swing right and traverse left" so the gear would always be engaged at the end of adjustment. Once again you are providing critical information instead of magic. Thanks a bunch.
I have been shooting VBR at 1k for 13 years and this is the second time I have heard this method of dialing past and then back. Unfortunately I had forgotten the method and attributed it to a certain manufacturer of scopes. Thank you for your advice again, I again learned something about my sport!
I dont comment much on channels but with all the great content being shared lately about reloading on RU-vid this has to be the most informative bit of information I've learnt outside of reloading. Its makes perfect sense and I now know why I was chasing my shots when adjusting my scopes. Cant Thank you enough Keith.
It’s like spring bind in a cars suspension You have to turn the wheel all the way to the left to get that spring binding noise and then roll partially back to the right to take the tension off of the spring because what’s happening is it’s sticking. Makes a lot of sense thank you 😊
I shouldn’t even give you a thumbs up for giving away my best kept secret. So much for just grinning when my adjustments work and the competitor on the next bench is cussing, lol. Yea, you get a thumbs up! Great video. I truly appreciate the depth of thought and insight you are willing to make contributing to our shooting disciplines. You have added much depth and understanding to my game.
Excellent advice! I've always suspected these conditions exist, but your explanation and, more importantly, your tips on how to deal with it, are the best I've ever seen. Thanks.
Ok, im relatively new to this channel and this is something I’ve never thought about. I don’t have the time at the moment, but I will definitely be watching again to make sure I picked up everything. This is great 🙌 party on
Well, I thought J knew everything. I used this technique , dialing past then going back. It was our first match. My wife's gun, was low, way low. We dialed passed 2 mins, then back down to the desired come up. Was on the 9 ring the very next relay. Thanks Keith
You have shed a whole new light on scope adjustments for me. A problem i have fought with in the past. I was one that carried a small ball bein hammer with me for tapping on the side of the scope. It works but was a crude way to do it. I see the light now. Thanks for the very informative video.
Thank you. You just made me aware of why I sometimes have trouble with fine adjustment of my scope and how to fix it. As soon as you described how the reticle is adjusted, I knew what you were going to say. A simple solution based on knowledge and understanding.
Thanks Keith. I've had issues with this and didn't know how to get by it... But now that you've explained it, it makes complete and total sense. Now I just have to remember to apply what I've learned.
Wooow man, what an eye opener, never thought about this, this video may explain some troubles I have been experiencing, awesome scope! but expensive😔! I use Vortex.
Agreed on single click adjustments. I've not found a scope yet that "adjusts" impacts by one or two clicks, _especially_ when changing direction. In other words, making *another click in the same direction as last time* _probably_ adds one click. But, making one click in the *opposite direction* just removes tension from the internals. That's also why zero "stops" (or marks) are important. Down to zero, then up to your come-ups in the DOPE book *each time.* And frankly, for the _vast_ majority of shooters, 1/4-1/2 MOA is *well* within the variation of one round to the next.
Great video. Spot on. I always tap the scope lightly but deliberately when I do any cluck adjustment on my scope. I primarily hunt and use the reticle marks and not in habit of wrenching on dials.
Thank you for this video. I was recently zeroing my rifle and I felt as though I was chasing shots all over the paper. I never thought of doing this. Now I'm going to head out and do it again. Properly this time.
Great explanation Keith. I have been using the over adjustment to remove backlash for a while. But still find myself slipping back into old habits sometimes of knocking on the top of the scope. Great reminder here. Thanks for sharing.
So simultaneous adjustment of both turrets must provide least friction when dialing up or right. In that way you reduce friction in both X and Y axis of the suspended tube inside :-)
I'm going to try this when zeroing my laser/iron sights for indoor bowling pin shoots-I'd been going 1 click at a time and not seeing any change in impacts and then suddenly way over corrected! If this works the savings in ammo cost/time well worth a whole year of Patreon!
There was a channel Max Ordnance Academy that did some awesome testing of scopes. Their light transmission, their click fidelity and so on. Sad they only made a couple videos.
Keith, thank you. I recently read somewhere that there is a proper way to set the parallax also. The author claimed to always start at the infinity setting and dial back the side focus knob until the parallax is set properly. He went as far to say that if you passed up the point of being parallax free, you needed to go back to infinity again to reset the parallax. I can't recall for certain, but I believe the term he used was also back lash. I have always set my parallax starting at the low setting working up. Is there a right way and a wrong way to set parallax? Thank you.
That whole thing about dialing up one click, seeing no change in POI, so going ahead and dialing up another click.... yeah, (activate sarcasm), I've never done that before.
An extreme case from a reputable US brand. Could dial several minutes windage with no tracking response. Click the elevation a few clicks and the windage poi ‘snaps’ to where the setting should be. Proves the friction lockup you’re talking about.
