Hi everyone I'm new to the forum looking for some info on making bullets. I recently acquired these two .43 Spanish Rolling block rifles and I'm anxious to get them out to the range. I've been gathering everything I need to make ammo for them however, I'm stuck at the bullet alloy. From the book I've been reading it recommends a 1:25 tin/lead alloy for this .43 caliber bullet. I have about 25lbs of pure lead I purchased on eBay but I don't know how much tin I will need to buy or how much to mix with the lead.
Here is a quick picture I took of both rifles in my shop.
