Test media; Water soaked catalogues
Rifle; Ruger a Scout in 450 Bushmaster with Leaupold 2x Scout scope
Load #1 255 Grain Keith style PB HP loaded over 29 grains of H4227
excellent disruption (big hole) 3-9" of the media and straight line penetration of the base of the bullet to 20". Alloy was = Lyman #2
Load #2 Hornady Black 250 grain FTX commercial loaded 17" of penetration great disruption of the media 4-9" then tapered down and great expansion but the Keith style was just as impressive.
Another test I did was a 370 Grain cast HP from one of my 480 Ruger Levergun at 1000 FPS it was impressive great penetration and disruption. The load is a easy shooting accurate from the rifles. These were cast from a MiHec Mould as well. The full wad cutter base of the bullet penetrating deep after it sheds the HP nose.
I realize none of this is scientific but from a co,parison point of view I was impressed with the performance of the HP in the same media. The FTX actually had more retained weight but penetrated less due to the width of the nose after opening up. Athe cast disrupted the media greatly then continued deeper with a full wad cutter base.
