Post em if ya got em.
Here's one.
A lot of peeps on here reload and shoot a lot of AR platform ammo.
When reloading for AR platform guns it helps to increase case neck pressure to keep the bullets from creeping forward when the bolt slams into battery. This will help insure consistent chamber pressure, velocity strings and accuracy. You can do this by always setting your dies up for slight taper crimp. Bullets with a cannelure won't require as much crimp and is easy to see. Thick wall bullets like Nosler and solids like Barnes will require more cam over pressure to insure a tight fit.
Note: if you are loading at or above max powder charge you do not want your bullet to slam or creep forward in the case neck to the point they engage the lands and especially in a .223 where chamber may not be designed for over 62,000 psi. Split cases and blown primers are not pretty and you may find yourself using a cleaning rod to punch out a stuck case or worse.
