What is the purpose/advantage of using a flat base or boat tail bullet. Caliber .223?
simply put the boat tail design has a aerodynamic advantage over the flat base.
So your going to have a better balistic coefficent.
(what does that mean !)
less resistance, flatter shooting, less energy loss over long distances, most times better accuracy.
ok, got it, thanks!!
And smoother bullet seating.
There has been a whole lot of research done over time to show that the flat base is a small bit more accurate over shorter distances (under 200 yards) than BT's.
That said, once you get to reaching out a ways the BT becomes the preferred choice for better stabilization due to a higher BC.
Do a search comparing both base types and you will find a wealth of information.
