I know that there must be plenty of us who cannot simply plunk down the cash (or run up the credit card balance :o ) for a Leupold Mark 4 or a Nightforce or the like.  Sometimes it's hard to afford the stuff that we'd like to have to support our hobby, and at the same time keep the mortgage paid, groceries bought, and good tires on the family car.  And I believe, from reading through old posts here and elsewhere, that lots of guys would be out there dialing up shots and connecting (on targets or on game) if they only had the equipment necessary to do such.  And again, from perusing posts here and elsewhere it would not be hard to get the idea that a minimum of 800 dollars would need to be invested in a scope before any serious attempt could be made at dialing up accurate long range shots.

But there is at least one excellent scope on the market which can actually out-dial most thousand dollar plus models, and which also has glass which is easily on par with much more expensive scopes.

I have a Nightforce NXS with 110 MOA of elevation adjustment.  It's a great scope (as it should be) but let me be the first to say that I really didn't need it (I just wanted it!)... :D  The glass is good, the adjustments seem spot on... I can't complain at all about it.  That scope set me back 1300 dollars.

I also have a Weaver Grand Slam, 6.5 to 20 power, which I've had for three years or so.  I've never had a problem with it, and I've never had to doubt its turrets.  The only thing I had against it was the gold numbers on the turret dials wore off fairly soon after I got the scope.  Weaver does need to address this (and perhaps they have in more recent models, I don't know).

However, I found a way to mod the existing scope turrets such that they are easily visible, and easy to use.

The dial caps are removable on the Grand Slam which makes it easy to take a small three cornered file and cut grooves in the outer face of the dial.  I cut three grooves very close together for the "0", and then cut one groove every 2 MOA around the dial.

By having the hash marks cut at 2 MOA rather than every 1 MOA, it is easier to count by two's when you're dialing up the turret.  The 2 MOA hashes are close enough that it's easy to split them visually for 1 MOA increments, and of course the 1/4 MOA clicks can be counted by feel.

I thought of using white paint in the grooves, but decided against it because I thought that the paint might flake out of there.  It would probably be fine to put paint into the grooves, but I chose something else... :) which has worked out fine.  Desitin.  The diaper rash cream. :D  It's basically zinc-oxide cream and it's an easy matter to rub some on the dial then wipe off the excess, which leaves the grooves filled.  I've not had any trouble with it flaking out (naturally) and it seems to stay put.  It seems to be able to take all humanly tolerable temperatures, too.  And your turrets will never get diaper rash.  :grin:

Anyway, there is also the matter of limited elevation travel.  But believe it or not, with the right base or rings, you will actually have an advantage over many scopes with 100+ MOA of erector travel.  Here's why:

Unless your long range scope with forty-leven MOA of erector travel has a zero stop you might end up losing count of the revs you've turned that thing, and you might end up a revolution too low or too high.  Sure you can memorize how far from absolute bottom your 100 yard zero is and then take the turret all the way in and count the revolutions back out.  But that takes time and concentration--two things often in short supply when an opportunity presents itself.

But with a 20 MOA base, or simply with a set of Burris Pos-align rings, you can add 20 MOA to the rear of the scope.  This will take a scope with 45 MOA of total erector movement (like the Weaver Grand Slam I have) to near bottom for a 100 yard zero.  That's a good thing--because you cannot dial the scope a rev too low.  Mine will go about 4 MOA below my 100 yard zero and it's out of movement.  I can dial it down until it snugs and bring it back up until the three hashes are on the mark, and my zero is there.

Most Weaver Grand Slam owners have already learned that the Micro-Trac turrets are second to none in repeatability.  Again, I love my NXS but it has no advantage over the Grand Slam in turret accuracy.  The Micro-Trac system is simply awesome.

As can be seen in the photo, I'm using Burris Pos-align rings, and I do have the 20 MOA off-set installed in the bottom of the rear ring, which raises the rear of the scope by that amount.  If you were to have a scope that 20 MOA did not quite work out for, Burris offers off-sets in 5, 10, and 15 MOA increments.  You can use them front and rear, and in any combination to get the actual amount of elevation you're after.

If you have a Weaver Grand Slam with faint turret markings, you might give this suggestion a try.  I find the turret amazingly easy to use (one revolution equals 12 MOA on the Grand Slam, by the way) and seemingly fool proof.

Now that is inventiveness!  Weaver target scopes with the Micro-trac in 12 and 24x have been around for 15-20 yrs. and are still one of the best bargins going. I'm curious as to why you didn't use one of them? the target turrets have horizontal numbers, (this is why target turrets work so well for ranging) and you don't have to remember how many revolutions. Simply unscrew the turret and set it at zero vertical (for say a 200 yd setting) and note the horizontal number, (say it is 2) 300 yds will be at 2.5, 400 at say3 and 1000 at say 6. Is that a 788 remington it is setting on?

Thanks for the Intel dump, Dan.

Very interesting, indeed.

 

There are actually a couple "closet Weaver fans" here on The OT that have heralded the virtue Weaver's for some time now.

The Sightron SII's have gotten some good press from forum members too for it's great tracking ability.

 

How far out have you actually shot this scope accurately?

That is a Remington 788.  It's got a 24" 8 twist Douglas XX .243 win barrel.  Great shooter...

I already had the Grand Slam which is why I used it. :)  I have used target turrets before (I have them on my Nightforce and on a Bushnell Elite 10X) but I still get lost sometimes on the revolution count.  It's hard for me to tell which horizontal line is which, especially in dim light--or as is more often the case, if I forget which line is my zero rev.

With the 45 MOA travel scope, and a 20 MOA slant base (or the Burris Pos-aligns) you can get your 100 yard zero on the last rev going down with the elevation turret---and it then becomes impossible to dial down too far--and you don't even have to look at the turret.  You just remember how many clicks up from bottom to zero (about 9 in my case here) and you back on to your 100 yard zero. :)  The three hash marks are sort of like "braille."  You can feel them and know when they are lined up facing rear.
