With a smooth bore & no rifling to spin these tiny projectiles you would think they would fly all over the place
"I know a dandy/airgun collector who take the liberty to outshot other guys with modern airguns for fun on competitions using a vintage smooth bore and original spitzer bullets or "spitzkugeln".
it not enough to compete with the first line but they shoot so good you can win against the common shooter with modern material.
he say its fun to watching them when he comes with his over hundred years old airguns,laughing when they see what it is. this stops when he shoot better then the other guys."

Obviously not!!!
Great to hear these old veterans are still going strong - both lots!
