In recent weeks I have caught up with an old shooting friend who was selling up all his gear due relocation/age/poor health.  We were going through his gear when he said "you might be able to use these in your .32-20" pointing at a plastic bottle of Lyman 311316 bullets.  I replied "I would think so, that is my handwriting and I gave them to you for YOUR .32-20".  We both laughed.

On bringing them back home I noted the label read 2008, air cooled clip on WW, 2% tin, heat treated, 27 BHN.  I got to thinking.  13 years on how are they holding up.

Put a bullet over the Lee hardness tester today.  20.5 BHN.  Stil lharder than linotype.  I was surprised.  Thought they would be softer by now.

Cheers from New Zealand

I have some 45 caliber bullets of the same alloy water dropped that are over 35 years old. I can use them to set nails heads without deformation and they ring if dropped on concrete. So no, they don't get softer very fast,
