I have been reloading for around 18 years now.I just started shooting cast bullets in the last several years.I have used cast bullets i ordered i love shooting these.I plan to start making my own by this summer.I'am a plumber and throw away alot of lead.I want to start saving this lead to us for loading.I will buy a lee pot but will use my big plumbers pot to melt the old lead into ingots.The ? is how much tin do i use per pound for hard cast bullets the lead i deal with is very soft and i have plenty of 95/5 solder lying around.Also do i add the tin when making my melts in the big pot or when i am at home in the small pot.Thanks in advance as i go i will have many more ?'s
