Would it be prudent to resize rifle brass after pulling the bullet and changing the powder but reusing the bullet.. would neck tension be lost after pulling the bullet since the neck would be stretched somewhat./.. TIN..
Good advice on checking tension against the bench, but if you are going to use the ammo in an AR style rifle I would go ahead and spend the time to neck size. Think about the cartridges violent trip from mag to chamber, that bullet has to stay put while getting slammed up and over the feed ramp and then again when it stops in the chamber, it could get pushed back or fly forward during this journey. That's just my opinion tho'.
