It water quenches to 30 BHN!!!
It is a 2-6-92 alloy, it casts some very nice looking boolits, it drops at the right weight (much like Lyman #2)....its good stuff!
But what is it that allows it to be quenched to 30 BHN?
These boolits were tested by somebody that knows how to use the tester (an LBT tester)...you all know him, he is a member here...but I'll leave it at that.
I cast some Ranch Dog TLC-460-350's over the weekend and fired one of them point blank into frozen ground...very frozen ground...2,050 fps, it weighed 231 grains when it came back out of the ground (346 grains was the original weight of the bullet without a gas check or lube)
A Beartooth 405 LFN/GC fired into the same frozen ground at 1,900 fps weighed 270 grains when it came out...
Its not a "brittle" 30 BHN...my first thought was maybe Rotometals messed up and sent me some Super Hard alloy...but those would be brittle I think.
Any ideas?
