I too have done a huge amount of alloy testing, I learned a lot from it so it wasn't a waste of time. I had a whole wall of the shop lined with many different piles of ingots all marked with what they contained, it got out of control quickly. The biggest lesson I learned is that using as consistent an alloy as possible is a good thing but a specific alloy for a specific use isn't really all that important. The proof of that is easy to see, just look at the huge variety of about every alloy out there being used and a great many people getting excellent results with them.
I did learn that in long range revolver grouping using a consistent BHN is important, vary the BHN within a group and the groups open up significantly.
Anymore I try to keep it simple, I had 800 pounds of clip-on wheel weights and I blended them all together to form one consistent lot of 5 pound ingots. I had 500 pounds of stick-on weights and I blended them all into one uniform lot. Almost all of my shooting now is with air cooled CWW with 2% Sn including rifles to 2000 fps. For very top end high pressure revolver loads I heat treat the same alloy to 18 BHN. For low pressure/velocity and HP bullets I use the stick-on weights with 2% Sn, air cooled of course because without the Sb it wouldn't heat treat.
Should i need or desire to experiment with alloys I have about 30 pounds of pure bar tin and a couple of ingots of Roto Metals Super hard. With the clip-on weights, the stick-on weights, the tin and the Super Hard I can make up most any alloy I might desire. I did experiment with the super hard and the stick-on weights, when wheel weights started to get hard to find I looked to see if I could duplicate the clip-on weights using stick-ons since the clip-on weights are far and away my most used. That is quite easy to do sans the arsenic. Since I do little heat treating anymore the As is a mute point but even heat treating to 18 BHN with the stick-on, Sn, Super Hard alloy no arsenic make no difference.
