That's a surprise. So what is the advantage of an open muzzle -- if the spears fall off and they take longer to load?
I'm not to sure Mr x, i think the main reason is you get a better view of the shaft,more accuracy.
I had a few moments today when the spear dropped off before i had wrapped the line over the spear to hold it in place.
I prefer open muzzle to closed now because of the clear line of sight.
Fortunately the prisons are full. Unfortunately, they'd happily free paedophiles & muggers in order to accomodate "an easy collar" and the retired vicar that refused to pay his above inflation council tax increase.

Very truerofl .
