Nah,
I wouldn't be "reasonably confident" that
my rifle's zero wouldn't change.
That's additional information, and it might make me say, "So
what if my rifle's zero changes a little bit?" What are you figuring on hunting, and what distances are we talking about? What I mean is, if I was hunting deer, and the average distance for a shot was 100 yards or less, I wouldn't give a hoot if my rifle shot 2" off from where I had it "sighted in" before I took it apart. Lots, and I mean
lots of people figure 4" groups are okay for deer 100 yards and under. Some deer hunters use open sights, and others even hunt with shotguns and slugs.
On the other hand, 2" off at 100 yards from where I had my 22-250 varmint rifle sighted before I took it apart
might make a difference - if I wanted to take a shot at a 300 yard coyote. The same thing applies to my 308 Norma Magnum if I ever draw another Idaho pronghorn tag (I haven't in the last 5 years) and want to take a shot at a 400 yard speed goat.
BTW, I grew up hunting with my dad, and to him, if he could hit a 12" diameter rock or dirt clod at a hundred yards, that was "good enough." And he killed plenty of mule deer and elk back in the day. So Dad worrying about a "zero change" caused by taking the stock off his trusty "three-oh-eight" and putting it back on??? C'mon.
