gentlemen,
i have a 30 br bbl that is marked "330 nk"
i just fire formed a new lot of brass and it all measured 0.331 .
question: do you think the neck is actually 332 ?
how much spring back does new brass have ??
this was fire formed with fast pistol powder, no bullet, no wad, pure powder.
as a clue to maybe not a "great" chamber, the brass must be resized or it will
stick in a wilson seater.
this is the third hand kreiger bbl that i have mentioned elsewhere.
the more i learn about the bbl the more i lean to cutting off and starting over with my reamer.( see my reamer thread)
