Linotype almost belongs in the handloading museum. It used to be easy and cheap, but - like wheel weights - has become a lot more effort these days. For a fellow who has access to lino, it still can be useful for alloying with pure lead, to make a somewhat hardened metal that works in a variety of applications. It also is very helpful to the fellow looking for increased strength/hardness through water quenching and/or heat treating (linotype contains antimony, which is critical for those esoteric pursuits).
Most of us, these days, have to go out of our way to get linotype. Unless a fellow is trying for something unusual - dangerous game bullets, rifle bullets, etc. - it's hard to see why we would. I buy pure lead whenever I can find a deal on it (and foundry lead when I have no other options) and keep a few bars of tin around. That is all I need for bullets from muzzleloader to full-throttle .500 Magnum, and I see no reason to complicate matters.
