Alloying WW with Monotype

[winshooter]

I generally cast with just wheel weights but then that's for under 950 fps. I have a chance to pickup some Monotype but have no clue as to how much to use in either WW's or stickons. First will Monotype easily combine with lead and second should I forget using it and just use Linotype.

Thanks,
Mike

What kind of numbers are you trying to get? Clip-on WW has about 0.5% tin, 3% antimony.

If you want to mix monotype and stick-on WW to make something close to clip-on WW:
10 lbs SOWW + 0.5 lbs monotype = alloy with 0.67% tin, 0.90% antimony
10 lbs SOWW + 1.0 lbs monotype = alloy with 1.05% tin, 1.73% antimony
10 lbs SOWW + 1.5 lbs monotype = alloy with 1.39% tin, 2.48% antimony
10 lbs SOWW + 2.0 lbs monotype = alloy with 1.71% tin, 3.17% antimony

melting monotype is an excellent way to get antimony and tin in an alloy.
you will need to flux PROPERLY if you get the grey bubbly on top of the alloy being made.

I read in an earlier post on the Forum that a member was using 75% WW and 25% monotype and getting excellent results for an all around 44 Magnum load. He was also using a 50/50 Monotype and WW for paper punching and getting a very hard alloy not suitable for hunting. Any comments on either of these mixtures?

I've used 3 parts lead to 2 parts Monotype to get Linotype BHN, and 3 parts lead/1 part Monotype to get 92/6/2 equivalent or actual. I run the melt at 800*+ for 10 minutes before final fluxing, and precede this with at least two fluxes during warm-up. ONLY REMOVE DIRT, NOT METAL.

Thanks for all the information. Looks like time to start casting some boolits and see what happens down range.

2.5 lbs monotype + 7.5 lbs COWW = alloy with 2.63% tin, 7.00% antimony
That is a little too high on the antimony and a waste of tin. You shouldn't go over 6% or it will be too brittle. Any tin more than 2% is unnecessary.

5 lbs monotype + 5 lbs COWW = alloy with 4.75% tin + 11.00% antimony
That bullet probably won't even make it up the feedramp without cracking in half.

For high velocity, you probably want to get something close to hardball (2% tin, 6% antimony).

Here's a couple tables for you so you can find a mix that works for whatever you want:
0.25 lbs monotype + 9.75 lbs COWW = alloy with 0.71% tin, 3.40% antimony
0.50 lbs monotype + 9.50 lbs COWW = alloy with 0.93% tin, 3.80% antimony
0.75 lbs monotype + 9.25 lbs COWW = alloy with 1.14% tin, 4.20% antimony
1.00 lbs monotype + 9.00 lbs COWW = alloy with 1.35% tin, 4.60% antimony
1.25 lbs monotype + 8.75 lbs COWW = alloy with 1.56% tin, 5.00% antimony
1.50 lbs monotype + 8.50 lbs COWW = alloy with 1.78% tin, 5.40% antimony
1.75 lbs monotype + 8.25 lbs COWW = alloy with 1.99% tin, 5.80% antimony

0.25 lbs monotype + 9.75 lbs SOWW = alloy with 0.47% tin, 0.48% antimony
0.50 lbs monotype + 9.50 lbs SOWW = alloy with 0.69% tin, 0.95% antimony
0.75 lbs monotype + 9.25 lbs SOWW = alloy with 0.91% tin, 1.43% antimony
1.00 lbs monotype + 9.00 lbs SOWW = alloy with 1.13% tin, 1.90% antimony
1.25 lbs monotype + 8.75 lbs SOWW = alloy with 1.34% tin, 2.38% antimony
1.50 lbs monotype + 8.50 lbs SOWW = alloy with 1.56% tin, 2.85% antimony
1.75 lbs monotype + 8.25 lbs SOWW = alloy with 1.78% tin, 3.33% antimony
2.00 lbs monotype + 8.00 lbs SOWW = alloy with 2.00% tin, 3.80% antimony
2.25 lbs monotype + 7.75 lbs SOWW = alloy with 2.22% tin, 4.28% antimony
2.50 lbs monotype + 7.50 lbs SOWW = alloy with 2.44% tin, 4.75% antimony
2.75 lbs monotype + 7.25 lbs SOWW = alloy with 2.66% tin, 5.23% antimony
3.00 lbs monotype + 7.00 lbs SOWW = alloy with 2.88% tin, 5.70% antimony

Great information and much appreciated. I should find something that will work for me with those mixtures.

Thanks again.

I have some mono available, and am blending it 7-1 w/WW's. Thirty-five pounds of WW's, 5 lbs of mono, and 1% Sn added. Makes a really nice alloy that can be cut 50/50 w/Pb for 38/45/whatever low-intensity cartridges, or used as is for high-intensity cartridges.
