IMO to a lot of you this might seem normal
But I figured I would pass it along non the less
Also I am on disability so the extra time isn't a problem
This morning I did the first test casting with a new mold that I made
Step 1 Pre heating the mold
I use a hot plate to pre heat molds and to keep molds HOT as I refill the lead pot with molten lead
But just extra casting of expected rejects will work just as well
Then cast some bullets starter bullets
These bullets are not really even looked at other than to confirm 100% fill out
These bullets and the sprue cut offs will be remelted
So IMO don't rush the mold heat up if you want perfect bullets
Step 2 Cast timing
As I cast
I have found that rushing results in more rejects and worse groups
So I take my time
I was casting 350 gr bullets for my 45/70's
I wait maybe 3 seconds longer than I see some others to cut the sprue off ( guessing the length of time )
But I find I get better results when I cast at a slightly slower speed
I admit I only did cast 40 or 45 bullets each of the 2 different nose designs out of a single cavity mold
If I need large numbers of bullets I have 4 and 6 cavity molds
Your thoughts ?
