Limited Elevation Adjustment
« on: May 18, 2004, 04:51:56 AM »
I am shooting smallbore rifle silhouette.  This is my second season.  I am shooting an Anschultz 1712 FWT  with a Leupold Vari-X III 6.5-20x40 EFR, mounted in a BKL  model 261 scope mount and shooting Eley Silouex ammunition.

I personally like and am quite satisfied with this combination, but there is one problem for which I am not sure of the cure; I run out of elevation adjustment between the pigs and the turkeys.

I have temporarily solved the problem by placing two shims cut from an aluminum Bud Light can in the bottom half of the rear ring.

Please advise me of the problems, if any, associated with my temporary cure and if possible provide advice on how to best solve the problem.

I am shooting an identical setup.  Anschutz 1710FWT with Leupold 6.5-20X40 EFR, using RWS R-50, RWS Target ammo. However, I am using Leupold Rings on weaver bases.   I ran out of elevation between turkeys and rams,  however, a single shim took care of the problem.  Was your scope zeroed before you mounted it to your gun?  Someone else might have more info on the BKL rings,  the only ones I have used are the Leupold and Burris.

I am shooting a CZ American with the same Leupold 6.5 X 20 scope with Millett rings. I also had to shim under the rear ring to reach 100 meters. I didn't want to invest in tapered hardware at this time and I haven't had any problems with the shims.
I would like to ask a question of both of you guys though. What was you deciding factor in selecting the FWT (Feather weight) model over the heavier 1710/ 1712 models? The reason I ask, is that my CZ with scope weights just a little over 7 lbs and it a bit light. With the weight limit at 8.5 lb, I was thinking about moving up in weight.

No particular reason other than to insure the complete setup, ie., gun, mounts, rings, optics would make weight.

Just purchased a CZ 452 American for my son and am setting his gun up the same as mine, although I plan to equip his gun with my current  6.5-20 EFR and am buying a boosted EFR from Premier Reticle to go on my gun.

Guys, BKL makes risers with I believe is 7 degree compensation. this would give you extra elevation. I personally make my own and machine them on the receiver with a .0020" taper in the front so I get the extra compensation.
Contact BKL directly and he can explain what you can do with what they make.

wplylar,

I use very special shims made from a once used gallon milk jug, the properties have been tested by a series of experts to include my hunting buddy bubba the tree rat dawg and was determined to be the most molecular structured material for sillywet use, teeth marks are used as proof marks of authenticity LOL, it actually measures to 3 thousandts and keeps my leuapold premiers dead center of the adjustment scale. Have done this for years and never noticed a problem of tracking, this would lead me to believe that it does not compress and will not scratch the scope, best of luck.

The differance between B class and Master class is less hits on the berm.

I spoke with David at BKL and he gave me a couple of options with which to solve the problem and alleviate my concerns.

I should note that he could, and would have solved my problem previoulsy had I known enough about the subject to understand what he was telling me.

If you are concerned about relying on "beer can" shims to provide the necessary elevation for your EFR to reach the turkeys and rams, I believe that David can help you solve the problem.  

His number is 877-255-2001.

I chose the FWT model just because I liked the Mcmillian stock on it,  I got one of the ones that are blue.  I also got it because I liked how you could easily add a little lead to the front of the stock. After doing this these rifles feel rock steady to me, and well balanced.

I don't mind being a little under weight,  this allows me to expirement with other scopes and rings/bases.  I currently am playing with a Leupold Var III 6.5-20x50 LR with a 30mm tube.  This is setup is quite a bit heavier than the one with the EFR.

Give Marvin Pearson a shout and have him make you up a custom tapered base and ring system.  This will take care of all your elevation problems.  His work is excellent!  Maybe he will see this post and answer directly.  I have his contact information on a different computer.

I would be a bit worried about putting undue stress on my scope tube by shimming a base and am a big fan of a single one piece tapered base.

I hate shims guys, why take a $600.00 scope and mount it on a set of $15.00 rings with shims and spacers and stress the expensive scope tube?
Just me.... may be I am wrong. 8)

Try a set of Burris Signiture rings with the offset inserts.

wplylar,
If you want to go one step above the Bubba Gump method, a fellow named Wayne Merier in Brunswick, Georgia (or Ghawja) makes some of the neatest scope mounts out of aluminium.  The rear mount is approximately 20 thousandths higher and brings your scope back to near center adjustments.  He makes them in a couple of different heights for both hunter and smallbore style rifles.  They are made for Weaver style rings and I too like the Burris Signatures for a completely stress free alignment.  I can email you pictures if you PM me.

your shims are OK, but I would find a set of rings that are different in hight, as one member said about 20 thou sounds right.  You could also get a rings lapping tool and try to lap out that difference - very lenghty process and no warranty that it will work,
So the best bet is to get the right set of rings,
why not try this fellow named Wayne Merier in Brunswick, Georgia ?
good luck!
