primer?

[DON WALKUP]

will winchester WSR primers work for 22-250 and .223?

thanks

WSR= Winchester Small Rifle. Those will work with the 223, which uses small rifle primers.
For the 22-250, you need large rifle primers, so, no, the WSR's would not work. You need WLR's.

Hopefully, if you are actually reloading, you should have one or (preferably) more loading manuals, all of which will tell you the right size primer to use for any cartridge.

Now to really confuse the issue! If you were to find some of Remington's URBR cartridges and reform them into .22-250 cases, you could actually use small rifle primers. I have reformed over 1,000 of the cartridges and found no disadvantages in using the smaller primers. Actually I found that the round to round consistency was increased by using small rifle primers. Occasionally I find a cartridge that was over annealed and has a slight hang-fire (you can hear the click of the firing pin just as the cartridge goes off.) I don't think that I have more than five or six of them in the entire collection.

Will Small Pistol Magnum primers work in a medium velocity 357 Mag? Powder, Red Dot or Herco.

If you substitute magnum for standard primers (or vice versa) you are essentially on your own, as the published load data will no longer be valid - unless you happen to find some that lists those exact components.

Switching ANY component can raise, lower or have little effect on the pressures generated, and there's no way to predict which way it will go. I developed a handy and efficient way to determine the effect you'll have, but it only works if you already have a safe load BEFORE you switch components.

If you don't have an established load for YOUR gun, the method doesn't work; you are developing load data from scratch.

The load I use in the 357 is mild. I know that it is listed for a standard primer however I did load some pretty stiff loads using H110 and it called for a Mag primer. I'm not one to mess around with loading data but the small regular primers are still non existant around here and I was hoping to us some Mag ones. And yes I do value my hands.
