shotgun primers

[Twicepop]

I understand the differences between rifle and pistol primers, but shotgun primers have me somewhat baffled. If load data call for one specific brand of primers will it cause problems to use another brand. The pressures most shotshells are loaded to are in the 8500-10,000 psi range (or is it LUP and not psi). It seems as though substituting one brand for another wouldn't cause dangerous spikes in the pressure by doing so, or not? I've never loaded shotshells before, I purchased a used press and refurbished it. I found hulls, a bag of shot, wads and a brick of primers, all I need is a can of suitable powder to get started. None of the "shotshell recipes" I've found use the brand of primers I have (Remington).

It is interesting that shotshell reloading data specifies a certain primer. It is also interesting that rifle and pistol reloading data does not.

I have always treated all makes of primers the same, shotshell and pistol and rifle.

The general rule for shotgun loading is to follow published loads exactly. Working up a load and looking for pressure signs isn’t possible with a shotgun shell, and substituting components can have unpredictable results. That said, I’d feel safe substituting a Remington primer for a Winchester, if the load isn’t at max pressure. For federal primers, I would stick to the published data.

The biggest thing between brands is diameter, there’s European (rio, fiocchi) and American (federal, Winchester). The difference in “heat” is a lot like rifle, slight differences in ignition. Have you tried ballistic product loading manuals for your primers?

It isn't just primers.....Wad brands/types as well are specified.

Stick to published loading data. If you look at any manual you can see what changes a primer or wad can make. I've been around three shotguns that came apart and all three were people who thought they knew more than the books. Like mentioned above, there's really no tell tale pressure signs.

Could you post up a picture of your primer carton? I have a lot of old manuals and maybe I could find a published load. Also need your wad and hull ID, and what sort of load you are after (weight of shot and speed).

You can tell which posters have a ton of primers and which post have realized we live in Socialist society and you use what you can find.

The rule is if a load is in the 8000psi range you can sub any other primer. Otherwise stick to the book load. Federal 209A is the hottest of all primers. This primer can make a load go extremely hot
