Scope with external micrometer Wind/Elev adjustments?

Hi,

I've now had two scopes go belly up on me on the adjustments where they don't move a couple of clicks and then just pop loose and jump over to where it should be, up to about 2/3" at 100m. One had it in the elevation, now one with windage. Won't say which brand as they were different brands so it seems to happen to them all. It's cost me three matches and a plenty of frustration so far and am fed up with stuff like this happening when I don't need/want it to.

I've seen a couple of external adjustable mounts, but mainly for BR where it is nice for one distance, but not really useable for repeated range switching. Does anyone know of a mount with external adjustments (micrometer etc) for both windage and elevation that is repeatable and accurate?

The frozen by Brackney and in his mounts. Have two, love them. Who told you they are not useable for multiple short range BR distances, or how did you arrive at that conclusion? Greg

I'm not a scope man but, it would seem the problem lies in the spring that pushes on the tube from the opposite side of the turrets. The fix for a long time has been to have Vic Swindelhurst in Canada or Cecil Tucker in Texas do their conversion on the scope. What they do is take out the small leaf springs that act as force against the turrets and replace these with a single coil spring at 45 degrees between the two turrets. I have a few scopes with the conversion on them and the clicks are much crisper now. There, now that someone has answered you watch the posts follow.

I had Tucker do a Weaver for me. Worked fine for a while then went TU. All 6 of my Weavers went that route, along with 3 Leupold comps. That's when I went with Brackney. No issues since except wind reading, seating depth, etc.
 
@FB: ;)

The scope I have the issue with currently will be sent back to have it repaired and then most likely will sell it afterwards for lack of trust. Price-point will make it less interesting for resale on this scope if it is modified.

I just found an article on 6mmBR.com on Mr. Beggs' rifle that is showing off a Brackney mount with micrometer adjustment. That looks like the ticket. I'm constantly clicking away 1/8 here and 1/8 there to keep centered, so a repeatable setting would be a must, no matter what the scale (less = more). I also don't mind zeroing every now and then, just as long as it is dependable during a match. Now to find contact info for Mr. Brackney.

I've only seen those on front parallax scopes, do they also convert side-parallax scopes?
 
I don't know the answer to that question, but I have a suggestion that relates to your problem. "Exercise" your turrets. By that I mean run each from limit to limit as many times as hand fatigue will allow. This should cause the parts that slide against one another during adjustment changes to smooth up somewhat, and improve the linearity of adjustment. I did not cook this one up, I read about it in a well done article in Precision Shooting Magazine, several years back. In addition to that article, I have seen one example of the method working that was quite convincing.

Some time back, I had stopped by a match at the Visalia range, and between matches had wandered down to the reloading area of a bunch of friends who come up to that match from Southern California. It seems that one of them, a fellow who regularly placed well in match results, was not having a very good day, and that the consensus was that it had to be his scope. A couple of his friends had offered him the use of their spare scopes, which he declined, when I asked him if he had ever tried exercising his scopes' turrets. He said that he had not, and asked me what I meant, which I explained. Well, he tried it, and went on to win a yardage, with the scope that had had the problem.

Given the price, you might try this one out, and if you do, let us know if it helped.

I tried that once with a problematic Weaver. When I got to one end of the adjustment range the mechanism froze and would not move. I thought about a Stilson wrench, but didn't have one handy. I sent it back, they sent it back and it was still junk. One should not expect much from a three or four hundred dollar scope!Greg
 
Greg,
The one thing that I gave serious consideration to adding to my post was that one should approach the end of turrets' range of adjustment with care. Your post reminded me of an incident that I heard about when a fellow became sufficiently agitated , ,during a match, that he managed to screw the entire turret out of a Leupold 36X. Not saying that you did anything similar, just that it reminded me. I think that a lot of good shooting has been done with Weavers, but nothing mechanical will be free of defects. Which scopes have you found to never have problems?

I'm near the 1/3 mark in terms of elevation, but on this scope it was actually the windage which is almost dead-center. On a previous scope I found out it was happening at a regular interval as if a thread was damaged and when you were fine-tuning in that range of the thread, you were pretty much done for.

I will try the exersizing to see, the scope is now around 4 years old and has seen regular use at 100m and F-Class (plenty or knob twirling all day long). I'll stick on my Leupy collimator and see if the tracking shows up visably when going through the range.

I have owned and used 6 Weaver 36x scopes and 4 Leupold comp scopes. Have had issues with them all. I now own and actively use 2 Leupold comp scopes frozen by Brackney and in his rings. I have never had a scope issue since...knock on wood!

I have never owned a March, but for me at least spending over 2K when I can get the same result for half the price is the determiner. Some find the lack of clicks troubling. Once you realize that using the target and the specific distances between points on it and knowing the drops of your load its easy as pie to go between 100, 200 and 300 yds. For group shooting precise placement of bullet on target is not as critical but holding POI sure is. I shoot IBS score and that game requires precise POI setting and holding of POI or you are toast.

Yours is not the first good report that I have had on Bob's system. I am glad to hear that you have a reliable setup. Thanks for the info.

I'm surprised

They are not more popular. However there seems to be some lingering doubt about external adjustments and the lack of "clicks".

One potential issue with the Brackney is the spring loaded leg that pushes the scope against the two adjustment points. It needs to be checked for proper tension once in a while. It is threaded and can back out. Greg
