    Posted: April/10/2008 at 19:06

I'm new and hopefully someone can help me with a question.  I just recieved a Zeiss Conquest 6.5-20X50 with the Rapid Z Varmint reticle.  This is the first real quality scope that I have ever owned.  Also, it is the first scope with a side paralax adjustment as well. 

Question, How do I set the focus and how do I use the parralax adjustment?  It has 50 labeled at one end and infinity on the other.  Inbetween is just bigger graduations.  I want to get this done right the first time.  It is mounted on a Savage MLII Muzzleloader using smokeless powder (Vit N120) and pushing a 300 grain bullet 2300 fps+.  It shoots .5" at 200 yards and the recoil is enough that it has killed 3 cheaper scopes, thats why I went to the Zeiss.

Thanks in advance!!!!!

Welcome to the OT

That is quite a scope for a muzzleloader, WOW  But on to your question the numbers on the parallax are yardages.  So if your target is at 200 yards you want to knob on the 200 and so on for other distances.  The knob on the eye piece is to focus the reticle to your eye.

Good luck

The only yardage marked is 50.  This rest of the marks are just lines.  It looks vary similar to the Leupold VXIII side adjustment.  I first asumed that each mark was for 50 yard incraments, but that did not work.  The reticle was moving on the target if I moved my eye position.  Mabye I did it wrong.

Welcome, cfrazier!
 
Just curious, why did you choose that much magnification for a muzzleloader?  6.5-20 is way more magnification needed for any kind of hunting except long range varmint hunting.  Even when set at 6.5X, you are sacrificing a great deal of field of view for the close in shots, and 20X is at least twice the magnification you need within any muzzleloader's effective range.  In addition, all else being equal in terms of scope construction, lighter, more compact, lower powered scopes are generally able to withstand recoil better.
 
If your muzzleloader is able to hold .5" groups at 200, you may very well have the most accurate muzzleloader in existance!

Basically, because I am working up to shooting to 500 yards.  I know quite a few people that shoot sub MOA at 300 and 400 yards.  Also, I generally take it to the range once a week.

Oh, if I use a 250 grain bullet and bump up the speed to 2800 fps it get somewhat flat(er).

Well in that case you just need to move it until the picture seems to be in focus at that particular distance.  But as soon as you move to another distance it will be off again and could cause your POI to vary quite a bit. 

That is why high power scope like that are not good hunting scopes.  If you get a scope that is 11x or under on the top end parallax does not pose such an issue.  A high power scope like that is made for long range shooting where you have plenty of time to get it adjusted correctly for the given yardage. 
Not to say they won't do the job, there is just more work involved in getting it set up.  And on a short range weapon like a muzzleloader you are really just handicaping yourself by having such a high power and having to deal with parallax at all.

Ah, if this is just a target gun then it should suit you fine.  I think muzzleloader and I think field gun for hunting.

I agree, for close hunting I have a 3-9 that is on Warne quick release rings that I can mount for that purpose.

Me too.  I would like to see a muzzleloader shoot sub MOA out to 400 yards.  That is an incredible feat I'd have to see to believe!

I can send you pictures if you want.  You have to remember that this is not an average muzzleloader.  It has been glass bedded and has 3 pillars.  It doesn't use black powder or a BP substitute.  I use a 45/70 spire point bullet, not a pistol bullet.  Also, it takes us a while to work up a load.  You have to try different powders, amounts, sabots, primers, barrel lapping, ect....   It is defintly overkill, but I like the challenge.  If anyone is interested in more information on this Savage, I recommend the following message board.  http://dougva.proboards34.com/index.c.cgi?board=Savage
 
Also, here is a .293" 3 shot 100 yard group.
 
 
Here is a .5" 200 yard group.  (Shots 4,5, and 6, I used the same target for different loads that day)
 
 
Here is a .75" group at 200. 
 
 
It is fun and challenging pushing it to its limit, its not your average muzzleloader.  The good thing is that Savage proof tests ever barrel before leaving the factory and book pressure is up to 40,000 PSI.

SO what kind of drop to you expect at 500 yards?  Cause that scope only has 45 MOA of elevation adjustment.  I can't imagine you could reach 500 yards with that setup.

Zeiss's website has it backwords, it is really 45 MOA of elevation and 36 of windage.  One, you have to use 20 moa bases.  Two, with a 200 yard zero and 2700 fps the drop at 500 would be 61.5"

 

So, back to the paralax issure, is there a way I can figure out what each indicator is at?  I basically want to just be able to dial the distance and be confident that it is right.

I don't know.  On my IOR even though it has numbers, most of the time while I am looking through the scope I just turn the knob with my left hand until everything looks in focus.  It always ends up being right on with the numbers in the end but that is how I usually do it.  As I practice reading the wind by the mirage and how it is moving and by turning the parallax so it is way out I can see it better then I just turn it back to focus and shoot.  I am into tactical shooting so I try to have as little movement as possible.  That has always worked fine for me.
