Fellas i have a quick question. Can you use a fireforming barrel for the first shot in a 6ppc if the chamber is a little bit bigger than the chamber your going to use to shoot. What i mean is this. I have an old shilen barrel that ron H chambered and it is worn out. I wondered if i could use this barrel for a FF barrel even though the chamber on this shilen is bigger than than the chamber on my new Dave Bruno barrels. I just dont want to put un-necessary rounds on the new barrels if i dont have to. It seems to me that i read that once brass is shot in a bigger chamber it will have memory and not work properly in a tighter chamber of the same caliber? The head space is also longer in the shilen barrel i have so i will have to push the shoulders back about .007 before i can shoot it in the bruno barrel. The bruno chamber i have requires a small base die if that means anything. Can i use the shilen or is this not a good idea? Thanks Lee
 
Lee...is the reamer yours?...the price seems a little high just to move the shoulder forward 1/8" and put the new reamer in...and set headspace...$240 would be for cutting a new tenon threading, chambering and crowning a new blank...
 
ya maybe i am a little high. I dont know what dave would charge to do this. his reamer is still smaller ( i have to use a small base die) the the reamer that was used for this old barrel i have. No worries as dave will be doing all of my ppc barrels from here on out. It wont be long and i will have what i need anyway. I was just wondering if i could use this old barrel for anything now. I didnt think it was a good idea but i wasnt sure for just the first shot since it takes two shots before the brass is comp ready anyway. Thanks Lee
ps. the reamer isnt mine, it belongs to dave bruno.
 
I always use a fireforming barrel, but I use the same reamer in both. I fireform my 30BR brass in a 22 cal barrel.
