linotype & CWW ???

[Russ in WY]

To get a good fill out , how much would be a good add of lino to a 10 lb pot ?? TIA Russ.

Good fill out is one thing, but what will you ask the bullets to do for you ?

What firearm are they for ?

Type metal can = hard bullets that can be brittle and fragment.

Load may have to be increased for harder bullets to seal the bore, Very good bullet fit may over come some of that.

What mold ?

What is your alloy now ?

What exactly is your fill out problem ?

Improper fill out may/can be caused by improper casting, mold temp, and metal temp.
Tin at 1 or 2% added to alloy is a nice way to help with fill out, But with proper casting and mold/alloy control it may not be needed.

I think a little more info would help with this.

good fill out comes from TIN
Lino makes your alloy harder .....adds tin but makes it HARDER

If we assume that:
COWW: 0.5% Tin, 3% Antimony
Linotype: 4% Tin, 12% Antimony

A lot of people find that straight WW casts just fine without any additional tin. You should try it first before making any changes. That said, here are the numbers for a few different mixes.

9.75 lbs WW + 0.25 lbs Lino = 0.59% Tin, 3.23% Antimony
9.50 lbs WW + 0.50 lbs Lino = 0.68% Tin, 3.45% Antimony
9.25 lbs WW + 0.75 lbs Lino = 0.76% Tin, 3.68% Antimony
9.00 lbs WW + 1.00 lbs Lino = 0.85% Tin, 3.90% Antimony
8.75 lbs WW + 1.25 lbs Lino = 0.94% Tin, 4.13% Antimony
8.50 lbs WW + 1.50 lbs Lino = 1.03% Tin, 4.35% Antimony
8.25 lbs WW + 1.75 lbs Lino = 1.11% Tin, 4.58% Antimony
8.00 lbs WW + 2.00 lbs Lino = 1.20% Tin, 4.80% Antimony
7.75 lbs WW + 2.25 lbs Lino = 1.29% Tin, 5.03% Antimony
7.50 lbs WW + 2.50 lbs Lino = 1.38% Tin, 5.25% Antimony
7.25 lbs WW + 2.75 lbs Lino = 1.46% Tin, 5.48% Antimony
7.00 lbs WW + 3.00 lbs Lino = 1.55% Tin, 5.70% Antimony
6.75 lbs WW + 3.25 lbs Lino = 1.64% Tin, 5.93% Antimony
6.50 lbs WW + 3.50 lbs Lino = 1.73% Tin, 6.15% Antimony

The boolit hardness should be between 12 -16 depending on which recipe you use.
I wouldn't go above 6% Antimony or your boolits will be too brittle.
