Wouldn’t your fire formed brass be formed to the chamber on the sacrificial barrel?Some guys say it impacts the load a full grain of powder when using a mag primer in a standard case but I'm sure that's just a "rule of thumb so guys will reduce their load a little.
RookieWYhntr is spot-on!
I just fire formed 300 rounds of brass in a sacrificial barrel and used mag primers because they were a brand that I don't use in anything and it was a good use for them. Didn't seem to make much difference on that load but there's a lot going on with fire forming which you won't have.
Yes.Wouldn’t your fire formed brass be formed to the chamber on the sacrificial barrel?
Short answer is ...well, maybe you are but I cannot really answer that for YOU.I’ve never considered fire forming detrimental to a barrel.....and I’ve done a fair amount....am I missing something?
Elkoholic,Zeke, are you saying that you buy 2 barrels when doing this? Do you do the reaming or have you got someone that does it for you?
