It's all good my friend. Like i said before, I know people will throw rocks at me for suggesting something different.And I can tell you BILLIONs of zeros have been done otherwise and been just fine. No need to waste all that ammo. Especially if it’s just a hunting rifle. You could zero in single shots. Single shots with time between to allow barrel to cool is best. If you’re zeroed with a cold barrel and then after some round the zero travels that’s normal bc the barrel is hot it’s a known fact that a hot rifle is less accurate from the reference of the original zero but as I said the barrel of your hunting rifle should never be getting hot unless it’s sitting in the sun. The hot barrel mentionings are mainly talking AR platforms. Idk where you heard that 10rnd thing but I’d bet money whovever is pushing that garbage is not a professional.
BTW these are the guys that put out the information and instead of shouting at them and calling them idiots, I packed up a rifle and went to the range to test it for myself.
