.308, is that wadcutter the 208 gr mould? If so they make nice round holes in water filled milk jugs and anti-freeze containers, it just blows the crap out of the back of them. :grin: I had one of the moulds years ago but dont remember what load I was using. Will look around my stuff and see ifin I can find it. As for shooting lead in a ported gun, my 10" ruger was magna ported and I used to get a lite build up of lead at the ports. An old gun smith said to smear a little breakfree around the port and it would wipe right off. My gun smith ported my 1895ss, he then back bored the bbl a couple of thousandth, have never gotten an lead on the ports. All I shoot in it is home made cast.
