So In Essence A BHN 10 Bullet could have a 30 BHN shell around it ? Would that render that Bullet at 30 BHN on impact vs 10 BNH in an non PC coated bullet?I read somewhere that someone tested the polymer itself at something around 30 BHN which I have no trouble believing.
So, is BHN only important in internal ballistics and terminal performance in the target game animal? When the bullet is in the barrel and in the tissue.
thats kinda the point with powder coat is you can run a soft bullet with no leading at high speed and still get expansion.
Ian is expert here I still use a star with carnuba red.
If I take this literally there is no difference in effect with a properly lubed and a properly powder coated bullet from the point they exit the bbl to impact of target. Yaw, tipping, wind action, flight time, going to sleep, and drop should all be in all practical purposes, equal regardless of either element.So, is BHN only important in internal ballistics and terminal performance in the target game animal? When the bullet is in the barrel and in the tissue.
Your experience mirrors the chart above. Remember COWW are not a controlled substance. Meaning THEY AINT ALL EXACTLY THE SAME!!In my experience, wheelwright bullets water dropped go about 19.9. BHN(LEE Hardness tester). PC them at 400 degrees, 20 mins. File a flat per instructions and test just like Normal on shiny lead removes PC. And I get 14.9 BHN Suits me. Your results may differ. Oh, forgot, added about 3 Oz 60/40 solder to melt.
