Hi,
I'm after people's thoughts on the suitability of 1/4 moa click turrets for air rifle indoor benchrest ( at our club its 30/75 yds) .I'm looking at a Sightron 10-50x60 scope but the configuration I want only has 1/4 click turrets and am not sure 1/4 click is precise enough as i've always used 1/8 click before. What are your experiences / thoughts on this?
 
Hi Chris:

I use a Sightron SIII 10-50 x 60 with MOA 2 reticle for BR as well as for FT shooting, it is mounted on a Steyr LG-110 FT gun...1/4 MOA clicks become 1/8 MOA clicks at 50 yards and while 1/8 adjustments would be desirable, I haven't really missed not having them.

I have been able to ZERO the gun very accurately with no issues and this Steyr can consistently shoot less than .170 ctc groups at 50 yards when the conditions (wind) are appropriate, I have won BR competitions at both 25 yard and 50 yards using this set up...I keep a 45 X Leupold Comp with 1/8 MOA adjustments from my .22 BR gun as an alternative, but I have not needed to swap scopes.

Sighton is built like a tank, consistent and reliable and the optics are as good as a Nighforce or a March...It doesn't have the optics of a Swarovski or a top of the line Zeiss but it neither has those prices, it is very clear and sharp and as good as or better than the competition.

This is no bragging, but please look at these pics: (Also posted on another site)
.170 and .150" ctc five shot groups at 50 yards using JSB 10.34 gr pellets at 20 ft./lb and NO WIND, but shot outdoors...Notice that I set the scope to hit 1/4" lower to the "X" for keeping my shooting reference. I then shot a fly after done with my practicing/testing and I afterwards I have shot a few more bugs for fun...If you can be dead on a fly at 50 yards with 1/4 MOA adjustments you will be dead on the 10X at the same distance.

Best regards,

Thanks Azuaro for the comprehensive response, it's exactly what I wanted to hear.
My choice is between the SSIII 10-50x60 LRMOA with 1/4 clicks and the SSIII 10-50x60 FTIRMOA which has 1/8 clicks as well as the MOA-2 reticle but it would need to be re paralaxed from the factory settings of 9-55 yds to 13-infinity. I'm speaking to the distributor today to see if the parallax adjustment is possible and what additional costs are involved. If it's not possible and considering your positive experience, I'll go for the LRMOA 1/4 click
Sightron have a custom shop in the U.S. so anything is poss but I'm in the UK and don't think I have access to the same service.
Best regards,

Chris,

Being in the UK I'm assuming you saw the Sightron article in the latest Summer Issue of Airgun World. Even though I'm in the US, I subscribe to it regularly just to catch articles like that one as you don't see them anywhere else over here.

Good luck.

Yeah, I've read that one. Cheers Dave.

I rang the distributor today regarding the Sightron 10-50x60 FTIRMOA and the possibility of adjusting the paralax range from the factory setting of 9-55 yds to the standard 13- infinity yds. I was informed that they actually come from Japan in the 13 - infinity yds format and are adjusted to 9-55 yds in the U.S. So the distributor only needs to ask for one not to be re adjusted prior to posting for which there is no additional charge.
So my order went in today with all my preferred requirements and I should have it within 2-3 weeks. :)
 
Dave:

I will like to read this Sightron article/review on Airgun World...Will you please refer me to the issue where you read it?...
I looked for it in the digital version of the July issue and is not there and after you mentioning: "We will not read here in the US" I assume that it is a good review
and will like to read it...

Best regards,

AZ

Chris:

Mine is not the FT model but the Sightrom SIIISS 10-50 x 60 LRIRMOA with the .250 MOA...The parallax goes from 9 yards to infinity as I received it from the factory...I have read some people complaining about larger gaps (in the adj. wheel) above 45-46 yards and up to 55....While they are a bit larger than lower distances, I don't see why this could be an issue...
The scope parallaxes PERFECTLY or at least I haven't had any issues with mine.

If you are not satisfied with the parallax, re-adjusting it is very easy as you only need to remove the frontal ring and make minute adjustments to the frontal lens...If you don't feel you can/should do it, I believe that there are some experienced shooters/gunsmiths who can do it while you are waiting for it ...I have adjusted 3-4 very successfully including a Zeiss that the factory would not re-parallax to 50 yards.
I made a simple tool for removing/adjusting the ring and adjusted the frontal lens very well and it took me no more than 10-15 minutes...I use this German made 3-9 x 36 Diavari in a new Daystate Hunter Regal XL and besides the nice looks, it is very sharp, clear and parallax ceased to be an issue at any distance.

AZ,
The issue you're looking for is the SUMMER Issue (making the 13th issue when you subscribe), not the July Issue. It's a good read and definitely retweeked my interest in swapping out at least one of my Leupold 36X's for one.
As for me, I'd rather go with the more traditional parallax, especially if they too will go down to ±15 yards, as you never know when the urge will once again strike to go out and buy another 500+ yard "chuck" gun. BWT: the one in the article, the 9 to 55 yd one, lists for £1050, which equals ±$1700.00, although I'm not sure if they're that much for us considering they come through the US on their way to the UK. Need to take a closer look.
Dave

P.S. I just checked and the MSRP is $1589.00 for the 10-50X60LRIRMOA, so that's the most you'll need to pay.

Thank you Dave...I don't know the fiscal policy in the UK but it will be worth checking out how much you will need to pay for taxes if you import it directly from a vendor in the USA...

Scope objective size?

As 69 mm Butler Creeks are rarer then hens teeth could someone please measure the inside opening of the 10-50x60 Sightron objective. I'm hoping to order a pinch style camera lens cap which clips into the threads on the inside of the objective bell.
Thanks
Chris
 
Back to the original question for a moment...

If you're one of those folks that need to aim where the hole goes then you'll need the closer adjustment. Alternatively, you can simply determine where the hole goes when you shoot and adjust the aiming point accordingly. Some folks adjust their scope while others just hold. Whichever of these fits your thoughts is the best choice.

Yeah, I'm a "aim where the hole goes" shooter. ( I shoot indoor benchrest )
In my head, it's a visual confirmation that I've got it right:).
I've now ordered the 10-50x60 FTIRMOA which has the 1/8 clicks and the MOA reticle. When they leave Japan they are set with the standard parralax of 13-infinity yds, it is Sightron who re adjusts them to 10-55 yds. So they will take one aside and leave it as set from Japan.

--------------

Since a minute of angle is pretty close to 1/10" per ten yards (or 1"@100yds), a 1/4" minute click turret would give around .025" per 10 yards, or .075" (not quite 2mm) at 30yds.

2mm is the size of the 10ring on the International airgun target, and though some find that movement a bit course, I have used several scopes with the 1/4moa turrets with good results. I have always shot airgun BR outdoors, and thus hardly EVER shoot directly right on the ten ring anyhow, due to wind, and don't feel the difference between 1/4" and 1/8" systems make any difference scorewise so long as I'm familiar with the scope ahead of time.
 
Be sure to check that parallax when you get the scope..and check it every shootin' match thereafter.

Why, have you had a problem with the parallax shifting on one?

100ths of Inches Can Mean A Lot

The answer is simple really. With tenths and even hundredths of inches mattering very much to me, I re-set my parallax every time I shoot a target for score or group. I also pull out my torque wrench before sighting in, to make sure my scope rings are properly torqued. Then there is the slow excruciating process I go through getting my benchrest gear properly aligned. Doesn't everybody?

Yeah, it goes without saying to check you are parralax free before shooting as the wheel is likely to have moved in the case/bag etc. I mis understood Wilbur's post, thinking he was implying that they had a problem with parralax shift/creep. I was worried there for a minute:).
