easter sunday
hey guys, i got out of my familiy engagement today(in-laws) because it was my birthday
of course all i wanted for my bday is a day to myself the weather is phenomenal for casting today!!! hope you guys are all getting some lead hot a couple of questions: first, i do not need to do anything to prep my molds anymore, just pre-heat them on the side burner and they are ready to rock; but should i be doing something to extend the life? these mold are well broken in now, but outside of the occasional smoking, i do not use lube or wax or anything, should i be? secondly: i had a little bit of leading in the 9mm the other day, but 100% none in the 357; i know the best way to prevent leading is proper bullet:barell size,but i am dropping right at 356, so i dont have the option to go bigger, the leading was not sever enough to be very concerned, but i am trying water-dropping again today question is, if i increase the lead temp will that make the water-drop more effective? other words, hotter lead+colder water=harder? thanks!! HAPPY EASTER!!

Happy Birthday!
As for the molds.... I just scrub my aluminum ones down good with a toothbrush and dawn before I cast again. I don't do anything afterwards. And remember to touch a Qtip with some sprue plate lube (or synthetic 2 cycle oil) to the alignment pins before you start. You don't want those things wearing and getting sloppy later. Some folks touch the sprue plate bolt/screw with the Qtip as well when it is hot and the oil will migrate down the screw to the plate/block contact surface. I use graphite for my sprue plate and screw lube, since I have trouble with oil migrating on me. Can't help with water dropping. I got no need for anything harder than air cooled COWW. I didn't cast this weekend. It's really too wet out in the yard, and I'm building a new reloading bench and shelves in here and I had to move the 5 or 6 tons of already-cast bullets out of the way first!

Look at you.... you're a lunatic! You're nuts! Who needs that many bullets?
You're totally outta control!

You need to shoot maybe 4-6 rounds through a clean barrel, then lock the action open and use a flashlight to light up the chamber end and look down the barrel. Yo will see the beginnings of the leading and where it is located if it is happeneing. If you don't see anything definite run a few more rounds through it until you do. Something to remember, running the mold hotter will actually cast a smaller bullet. Also the alloy you use can also determine to an extent the diameter as well. Here is a reference I had to really dig for that explains it a bit more, Referenced from, Quote:
You then use some very fine abrasive powder like the Bon Ami, I mentioned above or similar polishing compound, and lap the mold cavities using the bullets from each cavity as the lapping pilot. Just by adding a bit of wet compound and slowly turning the bullets in the cavities you can enlarge the mold to throw a bit larger bullet. The above can all be found over on Castboolits in the Molds section. Hope this helps and at least gives you something to try next. EDIT - as pointed out to me, in my state of incoherence this morning, I got things twisted up. Using some of the aluminum tape usually used for HVAC ducting you can enlarge the mold to a point.

I've been getting great results with spray-on graphite lube on the inside and outside of my molds. Haven't tried it on aluminum molds yet, but it works well on my Lyman, Saeco, and RCBS molds.

lol beagle
the leading is the last inch of the barrel, do not own a lubrasizer so I am just using lee alox at the moment. another thing is my factory bought lead has no issues evn though it is sized to .356 and sometimes even .355 I am familiar with "beagleing" the mold, but I rally like your lapping idea, I have never thought of that, I was also not aware that hotter temp drops smaller boolits, makes sense. I usually read people have good experiences with ALOX, I had thinned mine slightly but there is a ton of visible lube on the boolit, is there a better method? or should I consider switching lubes? like I said, no probs in the 38/357, only with 9mm which I only assume is moving at 50% faster speed than the snubby. I will slug my bore again today and see here I need tto start, thanks for the info on bullet sizes
