How do boolits like this for example https://www.reddit.com/r/reloading/c...gr_hp_in_4570/ start to spin?. This boolit is full diameter so the front of the boolit will engage the rifling and want to start turning yet the rear of the boolit is still in the case, so what happens?, does the boolit twist like a piece of licorice or does it start to spin while still inside the case?
