The USofA guys have postal Flat Rate boxes. As long as it'll fit in the box, it ships for a fixed price, up to 75 pounds, IIRC. Makes for a tough day for the postie, good for the sellers and buyers down there.
Not sure, but I think there is an international flat rate box. Might be worth digging around the USPS site to see. Could actually make it cheaper to buy by mail from the States.
I've actually seen a bit of Linotype or monotype at a scrap dealer in Edmonton, though it was a few years back (2004 ish), so I am certain it still surfaces. I am on the lookout for some for small caliber casting, so may just buy some. You get a lot more shooting per pound out of 50 grain bullets. Finding a scrap dealer that has some and does not sell it by the Troy Ounce, on the other hand, is gonna be even tougher than finding it in the first place. Most of them are pretty much on top of what the stuff they are buying should be worth, although there are still a few...
dargrim, what are you trying to accomplish exactly? Stopping leading? Look really hard at lubes and sizing. Look at the water dropping too, to harden up the WW alloy.
2 percent tin is about the max that will do you any good as far as fill out goes, or so I would be led to believe. I found that raising the temperature in my pot worked better. You need t be throwing really high tin percentages ($$) to get much harder than you can with WW alloy.
Realy take a good look at the castboolits site. Lots and lots of info on alloys and how to treat them to get what you want from them, as far as heating them or water dropping.
If you want to try the stuff, though, check out the TO Yellow pages under metals suppliers and make a few phone calls and get some prices to see if you can get some for less than mail order will cost you.
