Last night I decided to cast some 440 grain .500 bullets from my new Lee FPGC mould. So I cleaned the mould, dropped some WW ingots into my Production Pot, lubed the mould and sprayed it with Foster's drop out, brought the melt up to 700 degrees, preheated the mould and started casting. Properly dressed and with a full face shield of course.
During an interrum while culling bullets I said to myself "self" those are funny looking GC bullets.
Look more like FB's... oh well. During another interrum I grabbed a .500 gas check and it slipped over the base of a bullet. "That's strange" I thought. It appeared they would be way oversized even after a trip through the sizing die... oh well.
Another interrum later, I like to take my time, I thought it would be nice to know the diameter of the bullets as cast. So out come the calipers. The bullets measure a nice, uniform .459. "Great" I think, ".001 over bore size! If it wasn't for the gas check I wouldn't even size these bad boys!" So back to casting I go.
Of course, a short time later the light goes on.
.459!? It seems I had picked up a Lee 340 gr. mould, thinking and seeing .500 when the box was clearly marked .458! And throughout the casting process I didn't pick up on the little oddities I noticed.
Now, I know my mind has been on other things for the last couple of months, but this type of lapse is unpardonable! what if I had been thinking H4831 and picked up H110? Or Varget and Unique?
