Magnum primers have a thicker cup and different anvil shapes to work better with higher pressures and ball powder. This will help prevent the round from unintentionally firing upon chambering.
What are Magnum small rifle primers used for?
Magnum primers are primarily for ball powders (since they’re more difficult to ignite) but they will work with others. Be advised that the primer cups are thinner on magnum primers.
Can I substitute small rifle primers for small pistol magnum primers?
357 Magnum using small rifle primers…..they both worked nicely. Only problem that I could foresee is that the rifle primers have a heavier cup to withstand higher pressures of rifle loads so a pistol might not have a heavy enough primer strike to detonate but it sounds like you don’t have a problem with that.
Can you use small rifle primers for 357 magnum?
DickM Member. Small pistol and small rifle primers are exactly the same size (which isn’t quite the case for large primers), so there’s no problem there.
Are small rifle and small pistol magnum primers the same?
CCI has stated there is no difference between their small rifle magnum and small pistol magnum primers in mixture or cup thickness but their printed data shows a distinct difference.
What’s the difference between Magnum primers and regular primers?
The only difference between a magnum primer and a standard primer is the priming compound. “… magnum primer does is make more gas…” They make no gas at all. They merely burn a bit hotter for a bit longer.
What primers can I use for 223?
Remington 6 1/2 small rifle primers tend to work best in bolt . 223 over semi auto . 223/ 5.56 rifles. The CCI #41 is a Mil Spec primer very similar to their #400, all of the Small standard primer types (pistol, pistol magnum, rifle, and rifle magnum) will fit in the .

It’s just not safe to toss a small rifle (or small pistol magnum, or small rifle magnum) primer in place of a regular small pistol primer if you already have a max or near max load. You could shoot the pressure through the roof.
Do you need magnum primers for 357?
IMR4227 does not need magnum primers to ignite. It does tho, like a full case(at or near compressed loads) and a firm crimp for complete burn. As others have said, while H110/W296 require mag primers in small cases like . 357, most other powders do not.
Can you use small pistol primers in Rifle?
Pistol primers are not designed to withstand the higer pressures of a rifle primer. They are generally softer with thinner cups. I would expect at the minimum your fire pin will pierce the primers and melt the tip of your firing pin and possibly the total failure of and blowout of the primer.
Which calibers use small rifle primers?
OP, another vote for both the 300 Blackout and for using them (depending on brand) in pistol calibers. I’ve had good luck with small rifle primers – Remington (including the 6 1/2 size), Tula, and Winchester in 9MM, 40 S&W, and 38 Special.
Can I use small magnum pistol primers in 223?
They will work fine. I just primed 570 cases with CCI mag primers last night. That is all I use(mag primers) for my 223 loads. You may even see better accuracy.
