Not a problem..
If we look at how a primer is designed and put together we see that there are three parts to a primer.. Cup, Anvil, and Priming Mixture.
If we take a look at the Anvil, we see that it is 'pointed' toward the Cup. This creates a 'pinching' point where the firing pin will 'punch' the relatively soft Cup against the relatively hard Anvil with the Priming Mixture in between, which is what creates the flame to ignite the powder charge.
Now if we use a decapping pin to move the primer from the back, or the opposite direction, we see that there can be no 'pinching' taking place because we are moving the primer by the harder Anvil, especially considering the 'minimal' amount of force required to move the primer out of the pocket, compared with, the amount of force a firing pin exerts in an actual firearm.
The idea of using something (a decapping pin) that looks just like a firing pin to remove a primer does not set well in our minds, but in reality it is relatively safe to do so,.. with minimal force.
Just go slow and wear eye protection and you won't have a problem
