I use rolled solder also at times to help fillout & to "tuffen up" alloys but for fillout more than 2% is not needed .Tin will only harden lead so far then stop.
Most wheel weights contain close to that to start with that`s why there highly sought after & bring premium prices ingotized , there ready to cast bhn 9-14 ready to go !!
Rite now I have a supply of isotope lead which is 95/2.5/2.5 & I add a 4oz. bit of babbit toa 20# pot to tuffen it up a bit so my 358156 HPs will hang together after openin + i can push it as herd as it needs be to make it open !
