When your projectile decides to self-destruct just as it transits through the paper target,....

Re: Reloading demons
Apparently this was from an old Canadian Ross straight-pull 6mm Lee Navy. The bore for 6mm Lee Navy is .244, while common 6mm projectiles today are actually .243
This should not be anything that risks damage to the projectile, but some European projectiles, rather than having a flat base or boat-tail, have a convex base, where there is an inverse cone-shaped cavity. This is meant to allow the base to slightly obturate and expand just barely to fit more tightly against the rifling and in theory be more accurate as a result. But in this instance, the difference in bore diameter was just enough and the pressure great enough that the jacket base fractured and the rotational force shredded the projectile as it spun downrange. You can see the other 3 shots are rather close together, but this one, due to being unbalanced as it came apart, strayed from the tight path the other projectiles took.

Bought one of the first 650 presses and Mike took it back in trade for a 1050 after mine exploded a couple months later. Still have the burn mark on the ceiling from when it went bang.Suck My Glock wrote: ↑December 13th, 2020, 5:29 pm Well, it could be worse. I've been present when one of those Dillon 650s decide to detonate the primer magazine tube at a buddy's place. That's an attention-getter.

Re: Reloading demons
So,...um,...kinda think this ammo might be a wee bit hot.
