First you have to weigh your base ingots. Lets use 10 pounds of lead; to add 2% tin you would add 3.2 oz of tin. To make 6% antimony you add 9.6 oz.
Lyman #2 is 5% tin and 5% antimony, so adding it to WW's will never change the ratio. Modern (less than 20 years old) WW are almost .5% tin and 1.2% antimony. To make soft revolver bullets I use 3 pounds of WW's and 2 pounds of Lyman #2. The #2 is as hard as you can make with just these two materials. Note; a lot of scrap linotype has had most tin oxidized out and not useable in these calculations.
Using Super Hard at 30% antimony to your #2, 10 pounds of #2 plus 9.6 oz of SH would make it as hard as new Linotype. Lyman #2 already has 5% tin so should not have to add anymore for fill out.
