Casper50 , I asked a heap of people for slugs for my 12Bore Magnum Rifle, a couple said they would send me some (I would pay) but non came through, I even saw one of them selling some on the net, but again he let me down !

So I tried round ball & they work very well, I used a expensive ball mould first, then got one from Jeff Tanner, very cheap, fast work & delivery, mould works just fine .

Give RB a try while you look for slugs, they even shot well (smaller balls) in my Simpson 12Ga shotgun I just glued some sights on for a play.
