A gent from the local range is looking for an different lube for his riffle loads. He's using a 40 year old lube his dad made before he died. Its the type you use in a lube sizer.
I told him about BLL and he asked if itl hold up to his 2500 fps loads and i told him i thought that was common claim on here.
He know its a tumble lube. Btw.
