Primers need 3 things, the cup (which is the part you see from outside of the case), the primer compound (which ignites when impacted / crushed) and the anvil (the piece aganst which the compound is crushed by the firing pin).
In the Berdan system, the anvil is part of the case and is not replaced when the brass is reloaded. Berdan primed cases can be identified by 2-3 off-center holes in the bottom of the case.
The Boxer system incorperates the anvil into the primer and replaces it with each reloading. Boxer primed cases can be identified by 1 hole centered in the bottom of the case.
Unless you need to reload some obscure / rare ammo, your time, money, and effert ahead to work with Boxer primed brass (even if it means forming what you need from somthing else)
The materials used in the primer compound used to be made with corrosive salts, however (in the US) the compounds were changed in the mid 50's to a non-corrosive compound. Some forign mil-surp ammo is corrosive, and some is discribed as "slightly corrosive", if you shoot corrosives add soap and water to your cleaning routene to remove the corrosive residue.
*More than you wnated to know, isn't it?*

Tailgunner gave you a great answer, but wish to clarify one thing. The use of corrosive primers in US commercial ammo ceased prior to WW2; only the military ammo (and it varies by caliber) continued to use corrosive primers into the 1950s.
