Sorta having a issue with winchester 16g super #6 lead shot. Just about every shell I fire the primer ruptures with a little hole right in the middle of the primer.

In the same old 16g I have fired the canadian tire federal loads. But the problem with the federal is I get alot of clicks but no bangs. Primer too hard??

Is it the 100 year old single shot gun or the ammo?
 
Could be an unevenly worn firing pin that you may want to get looked at, but Winchester primers are soft and Federal are hard and crap IMO. I have had more fail to fires with Federal in any gone then any other manufacturer.

Much of the current WW 16 gauge ammo is made in Australia. The hulls are Cheddites and primed with Cheddite primers which have a known primer piercing issue. Looking at the photo of that old single I would be highly suspect of the gun though...
 
I sure hope that the mark on the barrel near the hinge is superficial. You may end up wearing part of the barrel if it is a gouge. It looks bad, but you have it in your hands to check over.

Yes they sure do. It amazes me any manufacturers still use them after all these years and the issue unresolved.

Low cost trumps good quality any day, it seems. Having said that, I still buy Cheddite for reloading. The only gun I own now that has a problem with them is a 20 ga Lightning, it gets Winchester primers. One of these days I'll pull the firing pins and shorten them slightly, it usually cures the problem.
Those shells the OP showed a pic of look to have Cheddite primers.
 
Hard vs soft primer material. Your pin is likely worn somewhat to a point and easily piercing the softer Winchesters while not hitting hard enough the pierce or fire the Federals. I have shot hundreds of the Australia made Winchesters out of all of my 16 bores (6 different guns) with no issues. There is also the consideration that chamber dimension vs cartridge dimension is allowing the Federal cartridge to sit deeper in the chamber causing the misfire. This is unlikely though. Place one of each cartridges in the gun and with a good straight edge to check and see if one sits higher or lower than the other. (across the breech face). One other cause could be the gun is off face a little from long use having the same effect. I think you will find the issue is with your old well used shotgun.

Your hammer spring is probably original too at over 100 years old. It is almost certain its weak and may not be driving the firing pin hard enough to strike a harder primer material. I think Struff hit the nail on the head, you have a wallhanger now. Retire it and move up to something newer.
 
I have a .410 double barrel from the 30's and have the same issue. I bought a couple of boxes of Winchester 2 1/2" shells from Walmart. I can fire either barrel and the shells will not go off. Looking at the primers, it looks as though there are very good primer strikes and no reason they shouldn't have gone off. If I try them again, they will go off about the third try at which time the primers are pierced. I think Walmart had them on the shelf for about 10 years so don't know if that has any bearing. I have not tried another type of shell yet to see if it makes a difference. The gun has new firing pins.
