I have soft lead ingots (80#bars) that I have broken down to a usable size. This lead is very soft. What ratio of this lead should I use with bars of linotype. I will be casting for 41 mag, 44 mag and 45lc. Thanks!
 
There is a spreadsheet over on the Castboolit site in the Lead and Alloys forum you can download. It is an Excell based one that works great for figuring out the amounts needed to come up with a certain blend.

It works in pounds so you will also need something to convert ounces to pounds if your adding small amounts of tin to sweeten things up.

Hard to give just a blanket recipe since different pressures need different alloy. Don't get carried away with getting things overly hard though. I am shooting an alloy which only runs around a 12 BHN upwards of 1600+ FPS out of my 41 and my 454, with no ill effects. Just make sure your size is proper and you use a good lube. Personally I like the lubes that White Label sells and have had nothing but great service from them. They are family oriented so if they don't just jump right on and shoot you a reply don't get upset, they will get with you to answer questions and process your order.

Hope that helps.
 
I use a 50/50 lead lino mix for my cast bullets,works out to Lyman no 2 alloy. Lyman no. 2 is either 90%lead 5% tin and antimony or 92%lead 2%tin and 6% antimony depending on when there loading manual was printed.
 
If you have a quality mold the weight of your dropped bullets will tell you what you need to know.

From a magma 230 grain mold I can drop pure lead at 240 or silver solder at 211, wheel weights drop at 232.
 
5# of your soft lead, combined with 4# of linotype and 0.5# of 60/40 solder will basically give you Lyman No. 2 alloy, which is a good place to be with the cartridges you mentioned.

Just a note on hardness and tin/ antimony mixtures:

Tin when combined with equal amounts of antimony produce more hardness than just adding more antimony and the tin will prevent poor fill in the molds and create a more uniform weight too. So before you add more antimony alone back up and add an equal amount of tin to keep the flow into the molds smooth.

One more note somewhat indirectly related: if your going to use Lee molds be sure and find some FULL synthetic ( not blended) 2 cycle oil for lube on the sprue and other places. You can thank me later. I've tried it all and nothing prevents ruining an aluminum mold more fme.

Great resource for mixtures and hardness needed by caliber......

I ain't casting no more as Missouri Bullets can furnish me with everything that I need.
Currently I=I purchase .38 and .44 caliber bullets from them with NO problems!
