    Back when I was doing all the testing I never heat treated an alloy with only 0.5% Sn so I can't answer your question from my own experience. I have, possibly had several papers written by the metals industry that discuss this very thing. I just now...

    Na, no job. Used to have one of those but decided I would be much happier if I didn't have one of those. See? Part time job, when I did have one of those job things in a 5 day work week I had 45 hours in by lunch on Wednesday. :veryconfu ...

    Confusing?? Am I reading that correctly in that your attributing the gain in hardness from HT to the Sn? Rick

    True enough, you can HT them, anneal them, HT them again . . . They don't care. Bottom line is that the bullet temp they are quenched at will determine the aged BHN. The other bottom line is they HAVE to be at that temp long enough for it to work...

    Brad, re-read post #52, this is explained to you. No! It won't! Not at the Sn percentages your using. After 5% Sn it will some and the higher past that the more Sn will effect your outcome. The temp you HT at WILL change the final BHN...

    Oopsie . . . Brad's HT was addressed in post #52 . . . NOT post #40. I'll edit that minor, insignificant little error I made in post #77. Rick

    Thanks, I addressed your Sn questions (in post #8) in post #30, the percentages of Sn were talking about will have little effect on heat treating. I got the impression that Brad assumed his lack of expected HT results was because of 1% or less Sn...

    It be time to back this thread up, in fact right to post #1. A picture or at least a drawing of 190X would be good for those of us that have no idea what it is. I've been sitting here quietly figuring someone would bring it up. Now that I think...

    I stand them up on the base (check) with all bullets touching to help keep them standing. I searched around restaurant equipment supply places until I found aluminum spaghetti pans that had flat bottoms. I attached brackets on the sides so that they...

    Wow BigDan that was only 1 week, others have been waiting about 4 years since it was announced at the SHOT Show. :mrgreen: I just went to the Lyman site and it still says late 2014 so they have plenty of time to change that. It's been put off 6...

    Welcome to CastBoolits Joe, The Lyman book is an excellent book, every caster should own one. There is some outdated info that keeps getting republished in each new edition but overall it is an excellent book. Here's the pdf version of the...

    That's correct, took me more than a couple of years way back when to figure that out. :mrgreen: Good luck on the steel critters. Rick

    Don't know about moly spay I've never used it, may work well ?? Search this forum for Bullplate Lube and how to use it, it is the preferred mold/sprue plate lube. Don't get any lube into the cavities, none, nada. Rick

    So what your saying is that the metals industry has it all wrong right? I'll let them know. The brittleness of a Pb/Sb bullet will be directly related to the percentage of Sb in the alloy, HT'ing that alloy adds little to no additional...

    No, that is not a what if, that is the metallurgy of Pb/Sb alloy. It takes X amount of time for the crystalline structure to grow, it doesn't just pop up because it got hot, the unknown for me was if a half hour would do it and it appears from your...

    I don't know that going from 1% to 2% Sn would change the final outcome much. I don't know that it wouldn't either but I doubt that small a percentage of Sn would make all that much of a difference. A difference in Brad's oven heat treating (he...

    Gear, I didn't choose WW alloy based on previous results. I used it because I had 800 pounds of COWW in 5 pound ingots acquired over time from different areas. I blended all 800 pounds together into one homogenous lot of WW alloy, still using that...

    I'll add to that my match revolver has throats that measure .357" across all five throats, the groove diameter measures .357" and all measurements are within a few tenths. Bullets sized anything over .357" will not chamber. Rick

    Yes but the reason I keep saying that my testing was with revolver is the relationship between throat fit is a different thing in a rifle (I can only assume). I use a mild snug fit in the throats. I can take the cylinder out of the revolver and...

    Oh yeah, I call it the "what if virus" and trust me, there is no cure for it. Every single "what if" you experiment with opens up 10 more "what ifs". Precisely why this thread and all of your testing is so fascinating to me. Rick

    I can't answer that, I've never used Lyman #2 for the same reason I've used very little lino. Higher Sb percentages increase the bullet shattering on steel targets and steel is the only targets I was shooting. The 5% Sn could well be enough to...

    As for age hardening your alloy whether air cooled or HT'ing the hardening/time curve is dependent on the Sb percentage, the lower the Sb the longer to reach final BHN. Higher Sn percentages will also effect the time curve but again, very little at...
