Primer question

[billykaldrich]

I am using a light load 5 gr. unique with 200gr swc and I was given 1000 federal large pistol magnum primers. Any one have experience in this area? Thank you Billy

Works fine, I have burned many cases of Winchester primers for regular and magnum loads, as well as many cases of magnum primers from various manufacturers. As with any change of load back it off a bit and chrono back up.

One of my friends who shoots light loads won't use anything but Magnum primers. He says it helps the load burn cleaner. And looking at the front end of his gun after he started using them I can see it works.

+3 works like a charm

I have always wondered about this: is there any difference between Magnum and standard non-Magnum pistol primers other than the fact the cups are thicker on the Magnums?

Guy?

Magnum primers seem to have a bit more bang. Hotter/longer flame??

When I was running a 40 minor load in production, changing to magnum primers

would pick up the velocity around 10-15 fps. The magnum primers seemed to

light off the small powder charge more consistently---it would shrink

my extreme spread by about 20 fps.

I can't say about all primers, but with the CCI, the standard and magnum primers are different. Besides the thicker metal in the cup, the magnum primers use a different priming compound. The priming compound in the CCI magnum primer is hotter than the standard.

I expect that the Winchester primers marked as usable in both standard and magnum loads err of hte side of being hotter to minimize any risks of not igniting a heavy load of slow powder.

Federal 155's are harder to light in my lightened trigger 625 and Vanek modified G21 but they are good enough for practice with the shortage of primers being what it is.

Not to steal the thread but...How about using Win small pistol Magnum primers for 38 super, 9mm, and 40SW? I have 2000 small pistol magnum primers sitting on my shelf and I would like to use them for something other then 357 magnum (which I do not reload for).

The guy I referenced above uses small pistol Magnums quite a bit, in both 9 and 40.

He says he gets an avg 11 feet per second increase and a cleaner burn (what's not to love?). If I ever use up my stock of standard primers I'm going to break into my old stock of magnum primers.

using magnum primer should be safe on that type of loads your talking about, so keep on shooting and be safe

I asked CCI that very question. They told me it was fine if you dropped off your powder charge a couple of grains or so.
