***I have changed my mind on lead hardness***
I screwed up and cast a batch of 200gr RFP booilts for my 350LGD with dead soft lead on Friday night to shoot at a friends Saturday evening. The mold didn't fill out and I had to run it way too hot to get a good cast but I was in too much of a hurry to care so I finished the batch of 200 anyway.
Gas checks, PC, size (Hey! These size EASY!) and load just in time to load it all up and head off for the night. Purdy FORD blue PC, showed them off to the rest of the shooters (had some loos ones in hand) and shot about 125 or so until it got dark.
Upon dispensing Hurricanes, I told them all about the PC and how well it works on high velocity rifle rounds, how it doesn't come off when firing and the clean bore they leave. Being skeptical, we took a boolit and smashed it with a hammer and that is when it all came together, dead soft lead, trace tin only, flattened out like play-dough! The PC held on though, making my point for me.
Hurricanes in hand, we trudged down to look at the targets and while I am no sharp shooter by any stretch, the grouping was solid at 12" off hand with no flyers or key-holing.
The bore was clean, just a speckling of powder, how could this be? I will cast up a batch of "appropriately hard" boolits tonight and fire them side by side with the soft cast ones from last weekend and see if indeed there is any difference from a bench rest. I am guessing that there will be no difference at all.
Thoughts!
