What makes a bullet 'blow up' in flight?
- Thread starter Dunraven
- Start date
Pushing a bullet to fast. Bullet becomes unstable due to twist in the barrel/speed.
One of the guys I shoot with in fclass has this issue if he pushes his 7mm Berger’s up around 3500+
Essentially the jacket comes apart

Simple,....Very high Rotational spin, that exceeds the ability of the jacket to contain the lead core.
nothing to do with defective bullets, then? simply speed? twist rate too great?
Usually it's just speed, but defective jackets, a bad crown, or horrible TIR can cause it as well....
More Muzzle speed increases spin rate, an with fast twist barrels the end product can over come the jackets ability to contain the lead core. some Target copper/lead bullets, are more prone than others. Most call it turning them into pie,... much like pumpkin chucking events.
