A fine article Wayne. I thought of locking handles once & thought I could do the same on my cooling stand with a stop & 2 nails. Never got round to it. If I was casting large bullets like you do especially using more than one mould [like you state in the article] I would try some type of locking device for the cooling mould.
Again, great article.
