The priciple is the same as ice skates. Friction doesn't melt the skate through the ice only the narrrow strip where there is contact.
The notion that the brief contact with the grooves is going to melt the entire lead bullet or melt away the copper jacket is not reasonable in my opinion.
Ever noticed the copper splash at the muzzel of rifles? Copper in its solid state doesn't splash over the crown.
