All we're doing is sending lead downrange here. We're not building a piano! You're bullets look good . . . shoot 'em! LOL!!!!

If someone else had of done to me what I did to myself . . . I'd have killed him. Humility is an asset. Heh - heh.

Don't worry if you have Antimony, it alloys well with Lead and Tin and Antimony does not present as surface porosity the way Zinc does on cast bullets. Antimony can be present in too high of a percentage and cause an appearance like the shapes on flakeboard or groups of crystalline gatherings in geometric shapes on the surface of alloy similar to the appearance of the surface of Galvanized Steel. None of your photos show a high percentage of Antimony.

Bullet casters run into low percentages of Antimony from using range scrap from pistol ranges and rifle ranges when they reclaim lead from jacketed bullets. I regularly do this. Core Lead from jacketed bullets is typically 2% Antimony and 98% Lead, common bird shot and .22 rim fire bullets are generally 2% Antimonial Lead also.  It is a soft alloy, usable as is for muzzle loading round balls and lowest pressure rifle and pistol cast bullet loads. 2% Antimonial scrap lead has a BHN of 6-8.

I also mix an alloy for general recreational use with 7 parts range scrap and 3 parts Linotype and end up with a BHN15 alloy very similar to traditional “Hardball” pistol alloy. My accuracy and velocity tests with my home made Hardball alloy are identical to certified Lyman #2 alloy, but I use the Certified #2 alloy for hunting as it expands, holds together and retains 100% bullet weight on game impact much better than Hardball does because of the 5% Tin, 5% Antimony and 90% Lead in certified Lyman #2 alloy having better malleability without fragmentation for hunting bullets.

There is a subtle difference between between the appearance of frost from a too high temperature thermodynamic error when casting and the appearance of frost from Zinc contamination.

Look at the last bullet on the right and the 3rd bullet from the right end in your picture. The opacity of the color of the porosity and the appearance of depth in the porosity of those 2 bullets, I would interpret as Zinc contamination from the picture alone and not from temperatures being too high.

Your bullets look great for a newcomer to casting but you still have a bit of zinc in your alloy. These will shoot fine but I hope you get some alloy with zero Zinc,

Ok, these aren't the .45's but the .38's, but just wanted y'all to take a look. Working on improving their finish. These were cast at just under 700 degrees. Some of the same ingots and also some new ingots. The ingots may have been cast out of the same batch of WW's, or not. I don't know. Casting cadence: fill mould, count to 15, knock sprue open and tap. Repeat. I was doing it at a count of 10, but it seemed the bullets were a little frosty looking. How do they look?

I revisited the instructions about making the lube. I heated both the JPW and the LLA at the same time. Don't know if that makes a difference, but not per instructions.

Gary, the bullets nor the lube was warmed. Just shop room temperature on a 65 degree evening. I'll have to try that with my next batch. I've got them in a cool whip tub awaiting their sizing. Once that's done, I'll work on warming everything up.

Yours are more than a little dark! Look back at my photo in answer#7 of this post. On the left is a box of Lee 340 gr plain base rifle bullets in 45 cal. Those dark bullets were tumble lubed twice with straight Lee Liquid Alox and they are definitely over lubed. The box on the right is RD 350 gr gas checked bullets. They were tumble lubed once before size/check and twice after...they are lubed correctly with 45:45:10 three times.

Your lube is on so thick that I am concerned you will put yourself on the list of people that can't stand tumble lube, call it very messy to work with, various other nasty names and complain that it slops up their bullet seating dies and smokes so bad when shooting that their vision is blocked!!!!!! You easily have 20 times too much tumble lube on your bullets. Tumble lube is a surface coating. There is no use to keep putting on so much that it fills the lube grooves of bullets. That will not make it work better.

Either formula of tumble lube needs to be the thickness of Hershey syrup, thinner than honey and easily pourable when the consistency is correct at room temperature.. You can add mineral spirits at any time to thin tumble lube and that will not harm it. Get the consistency corrected every time you use it as necessary.

I warm bullets in a brownie pan 5 minutes on warm in the kitchen oven for example. They don't get too hot to touch. I warm the tumble lube in a 4 oz bottle 30 seconds two times in my micro-wave oven. it gets very warm but not too hot to touch.

200 of your warmed pistol bullets in half of a square plastic 1/2 gallon milk carton needs about 1/3 teaspoon or less warmed  tumble lube added before tilting the carton 45 degrees and rotating  for 1 minute by hand. Gently and slowly dump lubed bullets onto wax paper and walk away. the bullets will be ready to load or ready to apply another coat of lube and  be loaded in 10 minutes if you have used warmed bullets and warmed 45:45:10.  Any longer than 10 minutes to dry and either you put way too much on, your lube was too thick or your bullets and lube were not warm enough.

Your bullets look like the lube is way too thick, you put way too much on and it was not warmed lube or warmed bullets.

45:45:10 dries nearly clear with 3 coats done properly as shown in my picture in answer #7 on the previous page showing the RD 350 FNGC bullets lubed 3x and ready to load. I'm directing you to look at the box of bullets on the right side of the picture, they are lubed correctly and look like they have no lube on them at all.

What do you have on those very dark bullets for lube? You have previously asked questions about tumble lube. Those bullets look like they were tumble lubed in the LaBrea Tar pits in California.

If you are tumble lubing and doing that, you have gone way overboard with about 20 times more than needed and I can help and advise you to get 45:45:10 applied clear and non tacky. Just ask.

Gary Ha, it's funny you ask. That is (or at least my version) 45/45/10. I made some up and that's what I used. I thought it looked darker than what everyone was saying.

I say “Shoot 'em!" Here's a close up of some that I picked out this morning. They don't appear to have the same porosity issue. They all came from the same batch. http://s777.photobucket.com/user/csparks1106/media/8A1AD8B3-97BE-41A8-9F90-D9D1E6462B32.jpg.html>

As it turns out, the .45's are right, and the .38's are left. I'll get this photo thing figured out eventually. Bear with me.

 You pinch and cut for sorting, learning to identify the markings on WW pieces also helps. The thumbnail scratch also helps..you can't scratch Zinc that way.

Additional familiarization with all your pots and what the settings produce in degrees is a good idea.

Your latest picture does not show the classic Zinc contamination or at least a lot less contamination,  the amount of Zinc that will cause poor fill-out and porosity starts at 1/2 to 1% Zinc in the mix, so the change in your bullet textures shows you were wandering in and out of the contamination level with different ingots.

Yes, they will shoot fine and my contaminated bullets shot fine too when they measure correct. Oddly, the porosity actually holds tumble lube better! You can, however get higher and higher with Zinc % that will make you want to just throw  the bullets away because they will come out so bad with really higher Zinc content and measure wrong also. Really high Zinc % in bullets will show as larger porosity bubbles than you have and also as bullets that visibly crack when cooling revealing SpongeBob looking voids.

The scratching and melting temp are the easy ways to control Zinc in your melt. Alloy assay is the next way to tell if it is already there but you will not likely be able to get that done easily or for free. Working on the simple ways yourself is the easiest.

Also you don't have to flame while fluxing, but then it is NOT reduction fluxing with oxygen deprivation of the surface for returning Tin Oxide to Tin back into the alloy. Yes You can light the flux smoke also and that will work easily if the smoke is hot enough. The ignition of flux actually makes the process less stinky and some casters routinely flame the flux just for that reason only with no concern or knowledge of reduction fluxing. It is just a choice, I prefer to conserve Tin and return it as I can when it is there by reduction fluxing.

Note also that the higher your pot temp is also effects the oxidation rate of Tin. Up over 800 degrees F., Tin begins to oxidize at a much higher rate and you will set up a continuous loss of Tin to oxidation  and it will stay lost without correct Reduction fluxing as lower temperature fluxing with no flame will leave the Tin as something you skim off the top of the melt and discard with Dross and dirt.

When I type in the little white block to post (as I am doing now) the lines are quite short.   Then when I hit “post reply” it shows up in the thread as very long lines but all there on my computer.  It also shows up with normal paragraph spacings gone unless I remember to double space between paragraphs.  I have cut my lines on this paragraph to see if that helps.   Maybe Mike can give us some guidance about handling this John John, it was because of my post with the pictures in it. I went in and edited the post and they lined back up.

Hmmm. It didn't work except for the first line ending with short. More thinking. John
