I cast my first bullets today to break-in my mould. I left the mould sit on my hotplate about 20 minutes while my lead melted. I started casting in the farthest cavity from the handles an increased to the second cavity after about 5 casts. Even after progressing to all 5 cavities it still took 20 or 30 bullets till the sprue plate was easily cutting all the cavities. And another 20 or 30 bullets till the bullets were dropping without any wrinkles.
After the moulds were warm to casting temp i cast about 150 bullets for measuring an weighing
I am a newby so keep that in mind when looking at my results. My alloy was 75/25 (WW/Pure) plus 1.5% tin
Weight variation for the solid bases 230gr - 7bullets / 229.5gr-7bullets/ 229gr-3bullets / 228.5gr-1bullets / 228gr-2bullets
Weight for the GC bases 225gr-3bullets / 224.5gr-5bullets / 224gr-3bullets / 223.5gr-5bullets / 223gr-3bullets
All cavities seemed round. Unless you figure .0005 is out of round. Bullets measured .431 to 4315
The only problem i did have was that the mould started to stick both opening an closing. At times i would have to use my gloved right hand to squeeze the front of the mould closed an at other times while opening the mould it would bind. Before i cast with it tomorrow i will have to measure the pins
All corners seemed to look good an square. I didn't measure but it looks like the GC has a slite bevel so that the rear edge is slightly larger. It may be an opstical illusion i will have to measure tomorrow also.
I would have to give the boys at NOE a big A+ on this mould. Good work Swede.
