Most commercial boolits are cast HARD to keep damage to a minimum during shipment... l prefer my home cast to be as soft as possible without leading the barrel.. My lead source is 90% wheel weights.. Clip-on weights are harder than the stick-on.
l prefer to use the stick-ons for hunting... Adding a pinch of tin to hep the mold fill out better when poured.. the clip-ons are great for targets... Esp IHMSA steel silhouettes.
People have been killing with lead 500 years.. 0nly maybe the last hund hrs have JKTD boolits appeared... Soft lead still kills as good as it did the first 400
