.223 Remington and 69/70 grain bullets.These need to be seated waaaay out of the case to even get close to a short jump.Too far out to suit me.
Now,what if......I use 222 Remington magnum brass? Longer neck,deeper seating of the bullet.
I can't find anything through google,only the reverse of this question.I have not at this point compared load data between the two case/rounds.Or pressure for that matter.
Is this a do-able safe option? Provided the case actually fits,as I have no 222 brass right now to play with.
