cast bullet size

[buggybuilder]

If I cast bullets in the same mold, group 1 with ww
group 2 lead pipe w/tin
Which will cast a smaller dia. bullet?
I have a stop-ring mold that is giving me a little trouble with bullet fit.
Thanks

depends upon the amount of tin ...if it's equal to or less than what's in the ww's it will be smaller just as pure lead would be ( except pure would be the smallest )
