I have encountered rifles that had been altered even to the point of rechambering to a larger
case/cartrige that had not been changed.
It is the obligation and responsibility of everyone that alters a chamber to give a good description
of the cartrige and special dimensions.
Also I have an update on more of the Superformance ammo. It appears that when fired in an AI
chamber that it is not as hot as a standard chamber. (When SAMMI loaded ammo is used while
fireforming) The extra chamber space allows the case to expand lowering the pressure.
Both chambers had the same free bore and neck size but one had been Improved.
Anyone else that uses this ammo please look at the brass and add your comments.
