On the re chambering of a standard cartridge chamber to an AI chamber, I have always heard that it is best to set a barrel back slightly (which wouldn't be possible with an Encore barrel without major alteration) so that the standard case will have a slight crush fit in the shoulder to ensure that there won't be any stretching in the case head area during fire forming.
As Idaho CTD said it is a wildcat and you can set the dies up where this does not happen. And by using the 25/06 head space gage with the 25/06 AI reamer it will not change the head space on your 25/06.
This change will improve the performance of the 25/06, Improve the brass life, and should improve the accuracy. + If you head space it with the 25/06 head space gage you can hunt with 25/06 ammo
with good accuracy and fire form at the same time. saving one firing to fire form.
