I do not wear any hand protection when reloading. I do wear heavy welders gloves, arm guards and safety glasses when casting bullets. I am very careful but lead pots drip overfilling moulds occasionally splashes so even being cautious minor burns can happen. I cast in open air so ventilation is not an issue.
I have been casting bullets almost 50 years and no signs of lead issues to date.
I do wash my hands thoroughly after reloading.
