  • Hornady Lead Pistol Bullets - Ruger Forum
    I have tested several different Hornady lead bullets with my Saeco bullet hardness tester I found the 45 cal 255gr "cowboy" bullets are BHN 10, as are the 38 cal 148gr LHBWCs and the 148gr Cowboy Hornady's 158gr LRN, 158gr SWC-HP, and 158gr SWC are BHN 12 All Hornady lead bullets are swagged
  • Brinnel Hardness - Ruger Forum
    A BHN 12 bullet will work well with pressures in the 16,000~18,000 psi range great for 38 Specials (17k psi max) up to 850 fps with fast burning powder or slower burning powder with velocities up to 1100 fps The trick with lead bullets is to use a powder with a burn rate that generates the proper chamber pressure to match bullet hardness
  • Shooting Lead Bullets in Revolvers - Ruger Forum
    The swaging process works very well with soft alloys in the BHN 10~14 range but is not well suited for harder alloys Both Speer and Hornady produce high quality swaged lead bullets, however the cost is typically more than double of cast bullets
  • cast bullets hardness - Ruger Forum
    I noticed there are different hardness on cast bullets by different makers What would be a good hardness for a 45 colt 250 to 280 gr Bullet for whitetail ny deer, within 50yrds?
  • BHN casting 44 magnum bullets - Ruger Forum
    just a question for you guys that shoot the 44 magnum, what BHN do you prefer when casting bullets for your 44 magnum?
  • BHN for 45? - Ruger Forum
    I think all this BHN talk is over rated Seems to be today's buzz word phraise (my 12 75 BHN bullets surpass the elasticity quotient for 22 4 gr of Reloader 74 powder, but 13 9 is blah, blah, blah) I cast for several years (mebbe 10) before I started thinking about BHN
  • Lead SWC hardness for 44 Special - Ruger Forum
    I got a hardness tester and tried the "pressure alloy BHN formula" and that lasted only a few weeks as bullet fit trumps hardness for leading and accuracy At least for me and my 5, 44 magnums, 3, 38 Specials, 1 357 Magnum, 2, 9mm, and 2, 45 ACPs After you get the sizing down, then try different alloys hardness if you want
  • Does Hy-Tek coating affect BHN? - Ruger Forum
    I would be interested in learning how coating a lead bullet would affect the BHN number For example I have some old Speer LSWC-HP's that I coated and used the same powder charge as before Is it still a 10 BHN bullet Shooting them was like shooting a totally different bullet Like the load
  • Swaged bullets - Ruger Forum
    Speer and Hornady claim their swaged lead bullets are about BHN 10 Using the formula for the lead bullet Brinell hardness number: BHN=chamber pressure divided by 1400 or to find chamber pressure, multiply BHN by 1400
