I have quite a bit of WW ingots, which I'm guessing is .5% tin, 95% lead, and 4.5% antimony.

I have quite a bit of ingots made from lead pipe and protective x-ray sheeting that I'm guessing is close to pure lead. These ingots are substantially softer than the WW ingots and also a duller color.

Any tin added to the mix would have to be purchased, which i want to keep at an absolute minimum.

At this time, I'm only loading for 9mm plinking so velocity will be below 1000 fps. What mix ratio would you recommend w/ the materials that I have?

50/50. You can water drop a 50/50 mix and get it substantially harder.

Will this ratio give good "fill out" in my molds with there being so little tin in the mix?

Clean, smoked, mold with enough heat(alloy and mold) and an alloy without Zinc and you can make boolits all day long. Perfect boolits too. 100% WWs or 50/50,soft lead/WWs

But i think your alloy will be to soft using 50/50. 2 % tin is the minimum requirement IMO. You would do better to mix linotype into the mix. http://www.thehighroad.org/showpost.php?p=5478388&postcount=6
