X-ray wall lead is the softest lead I had ever seen.
As that price - WOW!

I didn't have trouble with damaged bullets either when first starting with the bullet drop - however I still add the towel as some of the bullets have plain bases and I want no nicks or depressions.

Note, it is a good idea to have a slit towel across the top of the water container if water dropping. Dropping through the slit, is a definite safety strip to avoid splashes around your lead pot. You do NOT want a splash to enter your lead pot. It will empty all over you. To be effective, the water bucket must be close to the lead pot so the bullet can be dropped as soon as it hardens. This heightens the possibility of splashes.

I also once had a large moth fly into my 20 pound lead pot as I was casting - No idea why it did that - I was wearing glasses which were destroyed & the grey polar fleece jacket had to be thrown away - the jacket had a quantity of lead melted into the fabric on the chest and arms. I was lucky not to get very much on my face & have no scarring today.
