I was using 11mm steel but I can't get them at a good enough price anymore . So I decided to bite the bullet and make my own lead 9.5mm.. the fly true and hit like a truck
Nothing worse mate, had it happen a few times, last one was someone's spaniel with a rabbit I shot on a paddock, the fecker came out of nowhere, picked up the rabbit and hightailed it back in wood. What catty ya shooting ?.
You have to use Amber belt and if your using that and can't tie on then it's clips. Here's a natty with no band grooves tied with Amber belt. Never had one slip.
