my favorite method involves chambering it in the gun and placing your finger on the bang switch, pull it!
(with no other powder or bullet in of course, pull those out first)
And then you will have a mildly fireformed case to boot!

Just press it out. No biggie.

If its a starting to mild load and the wrong primer is Magnum vs Non Magnum wrong brand Match non match etc I would just use it.
If its pistol vs rifle etc I would NOT use it.
Buy a Lee Decapper die for $8 and you can now decap all normal sized cases without reszing. Put on your hearing and eye protection and decap as needed.

I was always told that pistol primers are designed to withstand lower pressure and, with somewhat softer metals, be easier to fire.
Some quick on-line research shows pistol chamber pressures - with some exceptions like the .454 Casull - to be 40,000 PSI or less. Even the .44 Mag only cranks out 36,000 PSI.
Looking at rifle calibres, .223 Rem generates 55,000 PSI and the .270 Win 65,000 PSI. Average is about twice as high. Presumably - and I stand to be corrected if somebody has better info - pistol primers could rupture if subjected to stiff rifle load pressures.
As to depriming live primers, I've done it, but gently and with safety glasses. Never had one go off - yet.

Interesting.
I have used rifle primers in pistol loads with no big difference that I could tell.
I know the cups are supposed to be made of harder metal than pistol primers so they need a good stiff blow to set them off.
I have never tried it the other way though.
I just might try it to see what happens...all in the name of scientific inquiry of course.
As for brass with live primers....I just throw them in with the rest and process as normal.

When S&W developed the 500 S&W it used large pistol magnum primers, they quickly found out that there was a problem with the primers letting go under pressure and the standard was changed to large rifle primers. Of course the 500 S&W has a maximum pressure rating of 60,000 PSI so it is not too surprising.
Why would you want to screw up a perfectly good primer? Just decap as usual and save it for some plinking or practice loads.

I don't know why you would want to degrade a pushed out primer to be used only for plinking.
In all the live primers I have pushed out, I have never seen any sign of a mark on any of them, from pushing out.
I just re-use them, or put them in the box they came from.

I'd be careful here. If you have pistol primers in a semi-auto rifle you could have an out of battery firing. This would be especially true in an m305.
