New Sheridan 2260MB: Here's my groups. What do you recommend next?

[WilsonLR]

Yeah, so I love the gun but it's consistently shooting right. See attached. Yellow arrows mark aim points. Everything was at 10 yards and 90 degrees in the shade. I shot JSB MATCH EXACT JUMBO HEAVY 18.13g and JSB MATCH EXACT JUMBO 15.89.

The buckhorn rear sight only adjusts for elevation so I'm stuck for L/R correction. I checked for cant. Maybe it's the hard trigger on the 2260. Maybe it's me. I don't know and am not sure what to do next. After the first two groups, I decided to aim at points to the left and it put the shots near the original bull but eventually, this thing has to dispatch Iguanas.

Second problem is my old eyes. Need glasses to focus on front sight. Forget about rear sight. Saw a great but boring video on the history of sights where it made mention of how the military designed iron sights around the capable vision of 20 year olds. So as much as I like doing things the old fashioned way, it looks like I'm into adding optics. Not many choices in red dots for 11mm dovetails but I did find a couple REFLEX designs at $50 and there's always a Bugbuster at $110. But I wonder if a red dot will really solve the problem of not being able to focus on near things. What about rear peep with glasses?

What do you recommend?

Try a rear aperature sight that you can adjust windage...

Right. A peep sight. There's this one for $60 but says "Can be used on Daisy Match Grade Avanti models 853 and 953 target rifles but ONLY if you use a globe front sight." My front sight has no attachment mechanism I can see. Not sure what can replace it and that puts the dollars closer to a scope. Williams has an adjustable peep for a dovetail mount that's around $40 ... requires tools to adjust.

So for the same ballpark dollars, which is better for old eyes?

peep sight
reflex red dot
tube red dot
Oh screw it all, BugBuster Scope?

TIA

If you are near sighted a rear peep sight should work well.  Because of an optical phenomenon called the Camera Obscura effect the rear aperature acts as a lens and you can actually correct for near sightedness by adjusting the focal distance from the aperature to your eye.  I find the large (3 minute or more) red dots to be too imprecise for the kind of shot placement necessary to kill small game humanely.  My eyesight is so poor that any gun I intend to use to kill things wears a good telescopic sight.               

[WilsonLR]

Thanks. Good to know. I used to have wicked great eyes but after 45 years of computer screens, it's farsightedness problem. Hence the hesitation with red dots and peeps.

Please keep us informed when you start "relocating" Iguanas to the hereafter.  I intend to make an Iguana Safari soon and I want all the tips I can get!

I would recomend this sight below. I have one on my pistol and did not have to mess with my front sight. Or get a Wiliams rear peep sight.(Just pick the right one)

A Bug buster scope is an excellant choice as well.

Since you’re considering red dots but only have 11mm dovetail grooves, I found this on Amazon for my P-17, has several (I think five) levels of brightness so I can shoot in bright sunlight (I have old eyes too) and choice of red or green dot, or various other reticle shapes. Battery seems to last forever too. Good luck:

'Peep" sight would likely help....even with glasses. Problem being the apature/peep sights that would fit that one would also need a new front (taller) sight to work right...can't think of anything currently that would mount low enough to keep the front sight....so think in terms of BOTH the front and the rear sight.


Reddot has helped...basically the immage is all in one focal plane. Same is true for "peep"sights (even with prescrition-eyes). It'sastill an "extraadd on",sticks up waiting to get knocked around, runs out of power at the worst possible moment.

[WilsonLR]

I see front sights that need a dovetail of some kind. Are there standardized bands or something I can replace the stock front sight with? Not sure what to search on. TIA

[Pb_Volare]

BugBuster and UTG .22/Airgun to Picatinny/Weaver Low Pro Snap-in Adaptor. You'll love it!   

[Ribbonstone]

The rear sight would work.

It's the height of the front sight that is the problem.

Simplest way to get a match type front sight on is to order the Crosman Callenger 2009 front sight base (CH 2009-029) and the little set screws (88-089).   It's made to slip on that diameter barrel and has the grooves to attach the match type front sight.

But it will be long for a 2260 barrel....could always cut off the extra.

If you could live with a post front sight,then the front sight, then the one from the Crosman 1701 would work (didn't look up the part number).  Also made to slide on that diameter barrel

They aren't giving away even the lower priced match sights....could scope it both easier and cheaper....or red dot it. Neither one has to be too complicated/expensive to work on a non-recoiling rifle that isn't going to be used at long range.

Indeed. Replacing the cheap iron sights with adjustable peep sights is about the same as a basic Red Dot or a low end fixed power scope. The question do all three work with old eyes? 

[Ribbonstone]

OK...two PROOF OF CONCEPT ideas for peep/apatrure sights. 

Either will cost nothing but alittle time.

#1. Glasses.

Use an old pair of glasses(preccritption or just safety glasses)
Small bit of black tapewith a hole poked in it (if you don't have black tape, then marks-a-lot whatever color it is to black).

DSCN2890 by Robert Dean, on Flickr


(I'd use a smaller hole in the tape for rifles....turens out I like a slightly larger hole for pistols.)

HAve to fiddle around with the placement to get it in the natural spot your eye goes to when you aim the rifle, but it works like an oldmanuaol set camera's f-stop.  Makes for depth of field.....so you actually see the rear sight/front sight,and target at once.



Another try for proof of concept needs a bit more stuff.

#2: temp. peep sight.
Leave the iron sights on the rifle,adjusted as they are.

DSCN2887 by Robert Dean, on Flickr

Object is to cut out that silver key-hole shaped bit from a softdrink/beer can.
Poke a small hole in the roundish part.
Color that roundish part black.
Bend it and tape it on (but allow ther bolt to cycle).

DSCN2888 by Robert Dean, on Flickr

Likely tke a few trys, rebending and retaping,but eventually you;ll be looking though the hole and right down the aligned iron sights.

Can then remove the rear open sight and try a couple of groups.
If you don't knock the delicate little thing, can put the rear sight back on just as aligned as when you started.



--------
yes...your link is to the same Crosman front sight mount....but try the above to see how well it works for you.

[Arkmaker]

Here is the red dot I bought for my 2240xl. Best one I've had. 3moa dot. Holds position. A little pricey (for cheapo me) but I'm sure happy with it. Also tried it on my 850 and was great there.
Also this one is made for dovetails mounting.

Here ya go...I put this on my 1975 Sheridan...this takes care of the front sight issue.. See "Track of the Wolf" site.

Great ideas all. I went to modify my safety glasses when I realized I had removed the peep sight from my vintage model 99 before sending it off to Baker Airguns for a refurb. With a 1.25 8-32 screw, I was able to attach it behind the breech. Voila. I shot 2 groups of 5 (18.13g and 15.89g JSP Exact Jumbo). I had to adjust the peep windage to it's extreme to get lined up on center. To get the elevation, I had to use the bull and front sight to make lower case "i". Fundamnetally the gun shoots right but for now I can shoot.

What can I do about the gun shooting right?

New problem, when I put a new CO2 canister in, there was a hiss when I dry fired it and felt it through the trigger. I quickly tightened the tube cap and got 11 shots. Is this a problem with me not tightening the screw holding the peep sight or just not tightening the tub cap enough?

Yes I used Pellgun oil on the canister. :-) TIA

[csitas]

I can support the tape on the glasses trick. I use it all the time .Takes a little fiddle to get it just right . Use as small a hole that you can make with a needle. Make it about a nickle in size. I have a second pair of glasses and just leave it for shooting. Use both eyes and it'll just come into focus.I used to shoot comp. and used it all the time , this dot thing is as old as time.

[Ribbonstone]

Wilson:Just waiting...you already know which way the rear sight has to move to make it shoot left. But with that set up (good test), would be more of a pivot than a side-slide.

Never a fan of the slot in the fill cap...if finger strength won't seal it, then you need a new seal.
