Not sure what temp this stuff burns at, but it seems highly unlikely it would be hot enough to set off the primer, or that the beetle could produce enough of it to sufficiently coat the rounds to have this effect.
Also, if this somehow did cause the cartridges to fire/cook off… pretty sure that would kill the beetle anyway.
Maybe its supposed to be the beetle that shoots acidic/high temperature liquid out if its rear?
