Rear ghost ring sight..useless?

[Bronco_85]

With slugs @ 30 metres I get the same grouping and maybe a tad faster without the rear GRS

I've read many good reviews about GRS
Am I doing something wrong...or is it just not for me?
If by using the ghost rings correctly I could get faster and more accurate that be great. But i thinks its no brainer: front sight in the rear ring then... BOOM!

BTW Im right handed and my strong eye is the left one...maybe it has something to do with my grs problem?

Try at a longer distance for 1 and try blocking the eye not on the side the shotgun is shouldered. ie if on right shoulder block left eye. You might think it looks like the front sight is centered but if both eyes are open your predominant eye might be fooling you. Just my .03 and worth what you paid for it.

 

[Bronco_85]

What I said in the previous post wasnt clear ...my bad
I dont use my left eye to aim even if its my predominanat eye

I close it just a bit so my right eye becomes the stong one.



but when I shoot with pistols I use my left eye

is the ghost ring mounted on the barrel or on the action?

 

[Bronco_85]

its on the receiver
the gun is a 590 A1

 

[legi0n]

You can't expect good (or even decent) accuracy when the sight is on the receiver and the barrel can move against it. Get barrel mounted sights and you'll notice some improvement.
I get 3-4" at 25m with the sights on the action.

I find the front sight on the mossberg with it's colored line less precise then a round dot style front sight for me. Some of the newer models seem to have sights more like the ones on beretta's

Well, on the 590a1 the barrel seems very sturdy im pretty sure it doesnt move while shooting. It has a bayonet attachement and they had to make sure that it wont move after you stabbed bad guys...lol

I took a file to my front sight on the 590.....I found it was way too wide for any sort of accuracy.....if one is able to say that about a shotgun, LOL. Anyways, at a 100 yards, rested, I can get 5 shots within a 4" group, that is pretty good for a Smooth bore barrel, and Foster type slugs. I also painted the front sight with some high vis paint!

Anyways, I find the Ghost Ring slows me down a tad when shooting close targets, like 10 - 40 yards, i can shoot just as well and faster with my head held up, so I can see over the Ghost ring......YMMV

If your sights are set up correctly and you are using the ghost ring correctly then the rear sight should have zero effect on speed.

With a proper set up of ghost ring sights, when you take your cheek weld, the rear ring should be completely "ghosted" out in you vision and appear as a blurry ring. Like any sight your front post should be crisp and clear. Is it possible taht you guys are wasting time thinking about lining up target, front and rear sights? Do you do that with your handguns and rifles or does it come naturally? I bet it comes naturally!

I'm not a big fan of sights with a stripe on them because I find they produce doubt regarding elevation. I use Trac Loc sights with the tritium insert but I also rely on the top of the post as my aiming point.

I also don't see how barrel mounted vs. receiver-mounted sights is an issue unless your barrel is really sloppy and moves even when the barrel nut is tighened down. You're still shooting slugs out of a smooth bore and a deviation of more than 3 inches at 25 yards has a lot to do with the shooter and not the gun.

Like any shotgunning, it's all about cheek weld, Baby!

I bench my ghost ring sighted guns and barrels and shoot groups at 50 yards (yes, I know it hurts!). I have found that with a consistent sight picture and smooth trigger press I can shoot 3 inch groups at 50m. On a good day I can shoot 4 inches at 100m with my Express 20" smooth bore and Trac Locs. You will also find that you need to try different brands of slugs in your gun to get the best results.

As for the speed issues that you guys have mentioned, I found that I tend to run my shotgun like I'm shooting an AR when shooting slugs and buck and that has helped me with speed. Like any platform, learn your fundamentals of solid and consistent stance, front sight focus, trigger press and knowing where your gun will hit. Start at 10 yards and focus on one hole groups with slugs then move to 25, 50, 100.

Then introduce multiple targets, I like to set up 3 IPSC targets and shoot 1,1,1, then 2,2,2, then 3,3,3. per target to work on transitions and speed.

Also, practise trap and skeet with a ghost ring sighted gun! You'll be surprised how much the rear ring is an aid to shooting and at how much your speed with that configuration is. I've found that if the bird is in the rear ring, press the trigger and poof!

Well said Earl
Its all about cheek weld and front sight!

I get 3-4" at 25m with the sights on the action.

The potential difference in accuracy can't be realized in the field, and would be more than offset by the greater difference between the two sights. When the front and rear sight are only a foot apart, that doesn't optimize accuracy either. I have a 590, my son has an Ithica with the threaded barrel, both have ghost ring and post sights, both shoot the same slugs equally well, which with Winchester Foster slugs produces groups of similar size to your 25 meter groups but shot at 100 yards from prone.

OP, I don't know if you are doing anything wrong or not, perhaps you have a very repeatable cheek weld so you experience very little shot to shot variation. But when shooting with just a bead sight, you must be indexing it against the receiver in some way. If you are just getting used to the ghost ring, that might be interfering with your speed, but the GRS should be faster in that you can shoot as soon as the front sight appears on the target, there is nothing to line up provided you can see the front sight though the aperture.

Here's an interesting test for you to try though. From a rested position or even from the bench, sight on your target with a GRS. Now move your head around, keeping the front sight within the confines of the aperture. What do you see? The front sight stays on the target with very little apparent movement. Now try that again, this time with a shotgun with only a bead front sight and no rear sight. Without a rear index, when you move your head, the bead moves right off the target. What this means is that when you are in a hurry, the GRS potentially provides a more accurate shot than does the plain bead although given enough time either will have you on target.

A solid, repeatable cheek weld with a bead can produce excellent accuracy, but I find a rear aperture cuts out the extra FOV that is not needed around your front sight. It kind of focuses on the target. Thats not to say a bead is a bad choice as practice will lead you to conistent accuracy. Some people dont find the rear aperture helps much, or even slows them down, but I find it helps make me a little quicker and more precise. Windage and elevation are alot easier to adjust with clicks instead of lining things up. Just my .02 cents

 

[legi0n]

Wow, some shotguns you have guys! 3-4" at 100m consistently?
There are rifles (SKS comes to mind) that can't do that with stabilized bullets and fixed barrels!
I myself sometimes punch touching holes but that's rather the odd exception than the rule.

 

[tritium]

I hear ya Legion but this gun has been very consistent with that performance using reloaded Foster slugs.

That performance was from a bench. It can be done.

I am going to the Range today, I will set up some 100 Metre Targets, and post results!

I'll be using S&B Special Sport (Low Recoil) because I am a wuss!

 

[7.62mm]

Ok, so went to the range this morning, I knocked my camera off the bench, it is now in 3 pieces. I took picks of my initial targets! then the next set, I hit the camera with the butt of the gun......I guess i need another Christmas present. I shot others and the groups were good, right around the 4 1/2" mark. I should mention that I had this 590 Threaded for Rem chokes, so I was using my Improved Modified Choke, this throws the best "Slug Pattern" LOL, out of my gun with the S&B slugs!

Nice shooting but apparently, it can't be done with an iron sighted smooth bore SG.

7.62 - Cheater LOL!.... (hey, I know you actually did it, which was the point I was trying to make!).

With a good sight picture and a good trigger press, 4 " groups are achieveable! I've also found that improved cylinder gave the best results with slugs.

I have an open choke barrel 18.5" barrel that doesn't produce these groups and my 24" barrel with a modified choke doesnt produce groups like my 20" IC barrel (and they all have Trac Loc sights on them).

Legion, you can produce the same results! Do it! I bet you'll surprise yourself! You're a shotgunner, try it!!! A good rest, solid sight picture and a very smooth trigger press and you'll do it! Shoot it like a rifle!

When I was with OPP, we used my privately owned gun for accuracy testing of specialized munitions because the bead sighted guns weren't capable of the accuracy ( I had over 100 to choose from and test fired at least 75! - all bead sights, all IC). I managed to shoot 2X2's at 25 yards with specialized munitions consistently.

 

[7.62mm]

LOL....and I suck at the accuracy game....there is no arguing that!.......Someone that knew what they were doing, well........

I tried. Spent some big $$ on slugs but it didn't get any better. Not even with a red-dot mounted on the action.
Best group was 4" at 50m with sights on the barrel but only once.
I must admit though, I always shoot offhand. My defender is meant for bear defense and my shoulder can only take so much slug practice. Benchrest never makes it. 5" at 25m is good enough for the purpose.
