Yildiz sight plane

When I shoulder my yildiz 410 side by side I see almost the entire length of the barrels. It points way to high. I have had this problem with other shotguns and I just added a plastic stock shim in between receiver and stock . Problem is no way to add that on double. If I add some sort of shim to butt plate will this have the same effect as shimming on auto ?

When you shim an auto's stock at the stock head, it moves the angle of the stock's comb up or down depending on size of shim. Unless you shoot with your head off the comb, which was done a 100 years ago when shotguns had 3" drop, I don't see how altering the angle of the butt plate would affect your head placement but you are going to have to try it and see. Even if it did change the sight picture, the shim at the stock would have to be considerably bigger because of the multiplying effect of having it at the stock's head rather than the butt. No harm in trying it to see if it works. Loosen both screws and put a wood chip at the top of the buttplate between it and the stock's end. Tighten screws and throw it up on your shoulder and see. If it works, measure the angle and cut a wedge to shape the length of the stock's butt end.

I loosened the butt plate and added nickels (2) , on top, until all I see is the bead. It worked perfectly. Going to order a shim plate for the butt plate. The other issue with the gun is that the stock appears slightly twisted to the right. When the stock is straight up and down the barrels aren’t level. Still happy overall with the gun because I didn’t expect much out of a 500 side by side.

Glad that worked out for you. Chris Batha, a noted shooting coach, recommends this simple exercise using your gun and a mirror to practice consistent shotgun mounting and insuring the gun is pointed correctly:

There are a lot of factors involved in the sight picture you get when you shoulder a shotgun. The drop at heel and drop at comb are very important in how the gun fits you, and so is the length of pull. It sounds like your gun also has cast to the stock to help a right handed shooter.

You have changed what is called the pitch of the stock by shimming under the butt plate. BPI and other places sell pitch spacers that are designed for the purpose of changing the pitch - is that what you are getting? I have one on one of my sxs guns that didn't fit just right.

A simple way to measure pitch is to place the gun with the butt down and slide it against a wall so that the receiver touches the wall. On most shotguns the muzzle of the barrels will then be several inches away from the wall. You can measure the distance and then the pitch is expressed in inches. Most of my guns will show 3-4 inches of positive pitch, but I wanted to tell you that my 20 gauge sxs Yildiz has no pitch at all - the barrels are flat against the wall. It's the only gun I've measured with no pitch. It sounds like your gun was about the same and you are adding pitch to it.

Increasing the lop will also give you a different sight picture and is the first thing I try when a gun is aimed up like yours. A slip on pad is an easy way to test this. Good luck getting it to fit you.

Called a gunsmith that is within an hour drive and going to drive over there with it when I get time. Think I am going to get him to add a grind to fit pad while we are making stock alterations, that way I can do away with having the shim and get some cushion from heavy tss loads. The length of pull on this yildiz is about 14.75 inches and all the guns that fit me are closer to 14. I am familiar with cast but on this gun I would call it a corkscrew stock. The thing has a twist to it. Kinda like if stock was straight up and down the left barrel would be half inch higher than the right barrel. If that makes any sense.

You're talking about "toe." Yildiz does that on some guns, including some semi-autos. It fits some people like a glove. If yours fit you, while the barrels would be canted if you tried to hold the stock vertically, if you held it naturally the barrels would be level. This is great for wingshooting, but perhaps not for trying to shoot a tight pattern like a rifle.

I made the mistake of playing with the stock shim spacers for cast and pitch on a gun last year and accidentally stumbled on a combination that fit me. In the old days , when I was ignorant to gun fit , I just adapted to the gun or sold it if it didn’t point right. Around here the local gun shops would try to tell everyone you could adjust your poi by shims problem is that if you aim a shotgun shims don’t adjust poi. The gun shoots the same for me but I did notice with some cast for a right handed shooter I don’t have to adjust my head and eye to the sight. When I shoulder the gun it is already pointing exactly where I am looking. May be obvious to some of you but I came up with Remington 870’s and old browning a’5. Didn’t matter if the gun fit or not I used what I had.

Story: The spouse and I went to get a Yildiz compact 20ga semi for the eldest daughter. I was set to buy it. My wife wanted to look it over after I inspected the gun. She threw it up to check fit in case she wanted one, too. I had her point to my eye with her eyes closed and then open them. First was, "Wow that fits you perfectly." Second was, "Uh-oh. That won't work."

It wouldn't work, because while both of them are tall females of roughly the same height, etc., the wife is RH while the daughter shoots from the correct side. Even if the girl compensated for the cast being wrong, keeping the toe of the stock from digging into her chest would mean holding the gun such that it would throw shots wide.

One of these days I am going to have a stock twisted correctly for me. Considering what a cast on stock does to a righty, watching one of y'all try a gun with cast on and toe in would leave me amused for a week.

Toe , cast , pitch dang things have gotten complicated.
I used to get a case of sears and Roebuck 7.5’s and brick of 22’s every Christmas and was proud to get them. I tried to make every shot count because they had to last. I have seen kids and even some adults at a gun range just see how fast they could burn through ammo. Like it was cheap firecrackers. I shoot turkeys with 6+ plus shell , not sure to be proud that I can now afford them or ashamed at the ridiculous cost.

Yep, I got $5/day limbing and loading firewood. .410 shells were more than $5.

A correctly fitted gun and quality shells cost less in the long run, because you miss less.
