Since cast bullets are elastic, and are known to obturate to fit the bore, would it make sense to assume that the bullet base, which is also elastic, might not deform to be squarely perpendicular with the bore under enough chamber pressure to cause bullet obturation? And how fast or slow a particular barrel is from gun to gun will make a difference as well. Due to human error, there is always a risk of crushing propellant pellets when loading bullets on top of them xe2x80x94 meaning pushing the bullet down too much.
