perhaps a stupid question, flaring AFTER priming?

    So me and a friend are both starting this process as rookies, and he brings me some .45 brass he primed without flaring. I told him they way in understand it, this is out of order, that you flare first, THEN prime. What happens if you run a primed case through the flaring die? Will it possibly puff out the primer?

    shouldn't be a problem so long as you don't have an expander with de-capping pin as some older RCBS dies had. I like the idea to start reloading on a single stage press doing batches of ammo. A good use for old tupperware containers.
    The only way I could see a problem is if you go really fast, the air trapped in the case could Possibly set the primer back. But I seriously doubt it.

    Nothing will happen. No good reason why you can't flare after priming.

    [Added - Dan and I were simulposting]
    ... unless, as he said, you have a rare expander die with a decapping pin. Even then the chances of setting off the primer are practically nil.

    With my Lee 4-die set, 1st die sizes and deprimes (and primes on the downstroke), next die is their I think 'exclusive' Powder thru flaring die (the powder measure dispensers thru the die and then flares the case, then the seating and finally their Factory crimp die. In the 3 die set the seating and crimping are done by the same die.

    That's when I usually flare.

    I prime all my brass prior to running it through the progressive, since I'm so particular about priming. All of it is belled after priming.

    Hope this helps.

    I flare and then prime, as the flaring may cause a case crack. Then I don't waste a primer, or have to deprime. No, using the proper die and proper techniques, flaring won't cause the primer to go poof.

    I've done it both ways. Never noticed any difference.

    What "I do" is irrelivant to anyone's work except mine and it doesn't matter a bit to the cases or primers.

    You can expand the case mouth before or after priming. On my progressive press, I seat primer then expand but on the single stage I usually expand and then prime.

    On progressives the case expander is usually hollow because that's how the powder gets dropped. No chance of air pressure being a problem there.

    Flaring

    I usually flare before priming but have done it both ways. The only down side to flaring after priming is the one in (pick your number) a few that split the case neck when flaring. I just hate wasting primers as I don't reuse them after decapping as I do deactivate them first.

    I always flare the case mouth after priming... the press requires it.

    I just flared a much of primed brass, no problem.

    Have to agree usually better if you flare first because you will find a few cracked ones. Out of 2700 only found 4 that were cracked.

    In the past I would flare first then prime. For the last 10 years I will prime and then put the brass away. If I need to flare I will do it just before adding the propellant as some bullets do not require the mouth to be flared. Not flaring the mouth will reduce brass work stress and allow the brass to last longer before it splits IMHO.

    Since I started which was a few months ago, It's always been like this.

    Resize/Decap
    Prime
    Flare
    Charge
    Seat
    Crimp

    Works out for me without a problem.

    If your using a Lee powder/belling die that would be in deffinite proper order. And in this respect, I always primer first then bell the mouths and have been doing it this way for many years withouyt a single problem.
