Removing live primer from factory ammo?

I'd highly recommend using a set of go and no-go headspace gauges if you're checking headspace. They're designed specifically for that purpose.
Having a good gunsmith walk you through the process is a good idea too. Most if not all of us here are amateurs, something I always keep in the back of my mind.
I got my go and no-go headspace gauges from Bighorn Sales in BC, Gary is great to deal with.

I agree,
I have a new 6.5 CM barrel and 6.5 CM no nogo gauges.
I haven’t installed this yet.
I’m still using the .308 barrel as a learning experience. But I’m about done with it .
I chopped 5 inches off it(for loss of FPS testing) and recrowned it.
I did have a smith ,show me how to check headspace,with a empty case.
So I’m good with that.
I’ve got to get a new recoil lug,so I’ll give Gary a call.
Much to do about nothing ! GEES ! Un less its something ultra rare or $$ round pull projectile, dump powder, remove primer and reinstall projectile !
If I understood, the OP wants to headspace his barrel using a particular factory round. Wouldn't either a full length sized case do the trick? Or even a neck sized one fired from that rifle work?
Simple Buy $2000000 dollar CNC lathe with live tooling or CNC mill Full inclosure then set up Bullet and load Tooling drill bit.. Start machine and leave building and town/city/country to be safe, hit remote start program. come back hole is drilled with absolute safety and don't even need safety glasses. (new machines have 1000psi coolant through spindle would be impressed if got hot enough to set off round)
Primers are sealed with laquer. You can run a box of primers through the washing machine and they will work fine.
Don't ask how I know this...
Some are, but they aren't all sealed. A thread on the subject came up awhile back, and I dunked 10 primers in a glass of water for a moment. Seated the primers and had 10 duds.
so here is some fun... I have 3 22br cases reverse primed... lol, lee primer deal, small rifle and primer inside exposed, in the bin,,,, 3 of them. all were flipped and I can with a shake, duplicate the fail in the closed hand press, in the easy press... I know 40 bucks.. primer tool... beware but its bad.... anyway first time removing a live primer with inside out... lets see....
Just deprime as usual.
Why not just remove the firing pin from the bolt, and ejector if it is a push feed, before using the factory round for a gauge?
That should get you close to safe headspace for that particular ammo.

Ok guys,sorry to get everyone upset.
I just wanted to set my barrel up to a factory rnd ,that grouped really well in my rifle.
So I googled the method I asked about, got a few hits,and thought why not just ask here.
After all it’s a Firearms forum,on the internet,just like the ones google provided.
I wasn’t going to pull the primer out, just wondering if it could be done.
As for hurting my feelings?, no you didn’t, but I admit, I got a little ticked
Anyway sorry if I said a few things I shouldn’t have, it’s not my style.
If I understand this right, you want to set up a barrel on another rifle to shoot as well with this cartridge as it did in another rifle? Or set up a new barrel on the same rifle?
Either way, the cartridge and it's dimensions are irrelevant. What matters is duplicating the CHAMBER dimensions. The cartridge is staying the same as it's a factory round... it's the chamber that is the variable. You're not aiming to just make a chamber theoretically optimized to this cartridge, you're aiming to make an identical chamber to the one that shoots this cartridge well. Same headspace, same body and neck diameter, same throat, same leade. If I understand what you're trying to accomplish correctly, you don't need to use the round to set it up, you need to duplicate the reference chamber properties so they're precisely the same. That would mean using the same chamber reamer, with the same wear on it. Even then it's not necessarily enough; the barrel contour, manufacturer, steel, twist, etc etc all have to be the same. You could have a chamber cut to match your preferred round exactly, but that's not really the question... the question is what are the dimensions of the chamber that this round shoots so well in? And even then, a different chamber may shoot this round as well or better than the original chamber.
Sorry if I misunderstood, but it sounds like the wrong question is being asked. Sounds to me like you want to duplicate one chamber to another barrel, which doesn't require an unfired reference cartridge at all.
Also, if you reload, you must have a set of calipers? In that case you could absolutely duplicate the factory round... pull the bullet, dump the powder, decap and then reseat the bullet to the same seating depth...
