Ron, How in the heck did you discover this? Did you stumble across it by chance? Back in that time I did some SERIOUS internet Scouring over this phenomenon trying to understand it? You were the ONLY person that i ever found speak of this. BIG KUDOS to you!!
When i shot the “original” Bullshop Bullet group, I didn’t understand this then? That Group was a Beautiful Little Clover leaf. My understanding of this stuff came after i had the Bullet mold made from 1 of Dan’s Original Bullshop bullets and i poured them of Pure Plumbers lead, As the picture shows my Rifle had NO USE for them.
It was after Ron had told me about the need for some hardness in the Bullets, That I contacted Bullshop Dan and asked him what he used? He actually told me Pure Lead From Plumbing, i started to Scratch my head? BUT THEN he described keeping the Solder Joints and adding them, BINGO!! There it was!! I asked Dan if he knew the Hardness after adding the Solder Joints? Dan told me that he did not Own a Hardness Tester, But he didn’t think it would Change the Hardness? He is wrong there, There is NO DOUBT it changes the Hardness
