I have a gen 2 12fv that started life as a 204 Ruger
I converted it to a 22-250, changed the bolt face, mag and followers. It is an internal box mag, 4.275 action screw spacing.
I just rebarreled it to 6.5 creedmoor.
Head space is set
Created a dummy round with a 139 grain Norma bullet.
Seated to 2.74 and it is too long. Won't eject and comes.in contact with the action. The round fits the mag and chambers no problem any thoughts on what to do?
