question about wheel weights
my question is this. what is the true brinell hardness of most ww's? i have read alot of range in this. my reason for this question is... i am casting for my 9mm's, this is a maiden voyage for me in casting. i was so excited to cast my own boolits and send them down range to that taunting piece of paper hanging there just waiting for them. well i finally got my first run cast and loaded and got my chance away from work to do this. it was beautiful. it seem like the more i shot the better the accuracy. well when i got home and cleaned up my pistol i had a lot of leading. i dont think i was shooting too hot, my load is 124gr rn with 4.0gr bullseye pushing it. i was very pleased with the performance,( at the target anyway) the recoil was light, the noise was moderate, my only complaint is leading. now, for what i read on another site(before i found this one) is that wheel weights are the right hardness for the 9's. now to enhance the hardness i do water quinch my boolits. i read that on here that most all the experienced casters do this, so i figure this is something i should do, or atleast until i get more experience in casting. what hardness do i need to strive for in my 9mm's and 38/357's and .380's and so on? i don't have a hardness tester, is this something i need to look at getting? also is there a possibility that i may have got some zinc in my melt? i try to pick those out, but once again, lack of experience will miss a few. as always i'm looking for wisdom from you guys.
