If your bullet is sized a thousanths or 2 over the groove diameter , and you use a good lube somehwere around 1000 fps should be possible. You can toughen the stuff up by adding a bit of tin. As you have already mentioned you can blend it with wheelweights to get the alloy harder. Wheelweights are quite a bit harder nowdays than they used to be. You can also mix it up with some of the rediculously hard commercial hard cast bullets and make a pretty decent alloy. |

The most expensive bullet there is isn't worth a plug nickel if it don't go where its supposed to.

Gas Checks. I use them in 30 cal and 8mm and get hunting accuracy with
a soft mix. I cast straight linotype get 2200 fps from the 8x57. Straight plumbers lead is probably too soft to get much speed. I cast all of the pure lead I get my hands on into fishing weights so I will know what I'm mixing in the pot when it comes time to cast bullets. For casting for ammo that the boys will shoot up to hear the noise I use whatever is cheapest but once in a while I cast some bullets just for me. Then I look up the mix I want to try and use parts(oz) of pure lead to parts(oz) linotype to get the right hardness. I don't ever try to remember this cause I never can. My brain is pretty cluttered up at the end of most days and I don't trust my memory so good any more. Alan |

You will probably reach your velocity limit at around 1200 fps,
assuming correct bore fit. You might extend up to 1700 fps with a gas
check bullet. Rather than blending, you may want to use it for trading
stock for some WW alloy. There is always a BPCR or ML shooter wanting
pure, although I shoot Ww's in both most of the time. Get some WW's
though, and with water quenching, or oven tempering, you can push
things up near factory velocities. My best, higher speed results were
in a .223, at 2780 fps, for 1.5" at a hundred yards. Everything better
be very right though, to get this out of lead bullet. Bore condition,
bullet fit and hardness, gas check, and good lube.
