Take an even safer route, dont use a bag when you are on the course!
I zero my Sightron turrets and I have not knocked the turrets, once I have started to shoot, only when taking it out of the bag once or twice. If you did knock it round a couple of clicks on a shoot, you would have a good idea what to allow if needed as you would know how far out you were from the markings.
I actually dont find it is a real problem to be honest. I tried taping the turrets and the rest but dont bother, and just make sure that if I re set my zero, I then zero my turrets.
You probably know but it is a .050" imperial hex key(a bit of an unusual size). You can buy a neat driver handled version on line made by companies such as Bondhaus for around a fiver posted, this makes things a lot easier.
