I feel like this is a stupid question so please be gentle with my feelings. I'm stocking up to reload for my Glock and I'm curious about 40 cal vs 10mm when looking for actual bullets to put to brass. The supply chain is limited and I find more 10mm stand alone options and not very many 40 cal stand alone options. However, I see them listed together on many sites. Are the bullets interchangeable as far as reloading to 40 cal brass?
