Hello, I've got a new model army I've been messing with and aquired a bullet mold from Kaido Ojaama and have been trying to get it to cast properly. I've leemented the mold, cleaned it until I've gotten tired of doing so several times. I'm casting with pure lead and have also tried a bit of tin with a 50:1 ratio to keep the lead from being too hard for these repro cap and ball guns. I've found a rate of flow from my lee 20 lb melting pot the mold likes and I've experimented with slower and faster pour rates. I've experimented with what angle the mold is at when pouring, where on the sprue plate the stream lands and I've found it functions best right in the center of the hole. I've experimented moving the mold around while it solidifies and keeping it still. No real difference. I've tried with lead pot temperature ranges from 700 all the way to 950 and around the 800-950 range seems to perform the best. I've taken a hand lens and inspected all of the vent lines that directly intersect the cavities and have removed burrs. I've found the mold casts the best preheated at around 470 to 500F after which it starts to have some problems. I've tried heating over that and have warped the sprue plate (replaced it twice) and have caused damage to the mold several times. I'm thinking the plate that's on it is warped again which is disheartening since I've been so fearful of heating the mold past 500F to avoid warping. I've experimented with both the tightness of the bolt for the sprue plate hinge as well as the bolt with the sleeve the plate locates on when closed and have only been successful in worstening either the failure to fillout at the bullet base or the flashing. I've seen no change in my success rate. No matter what I've tried to do to this mold to get it to cast correctly, I never get good base fillout. I get either incomplete fillout, or flashing at the bases, never in between. I will get both issues on the same cast and some bullets will have incomplete bases and the rest have flashing. I will get bullets with extremely small bits of flashing that are hard to see even for my young eyes and I consider these "successes" and can move the flashing over with my finger nail to be able to insert the bases of the bullet into the revolver cylinder though sometimes it's still difficult. I'm getting 1 and uncommonly 2 good bullets every 4-6 casts on a 6 cavity mold and I'm estimating that to be a 98ish% rejection rate. I have a couple of other molds from lee, a round ball mold in 451 I've abused but still gives good casts and a .456 conical mold that I've taken care of and have extremely easy success with casting and getting excellent bullets. Is there something I'm doing wrong here or that I'm missing? I've been extremely patient with this mold as it has at least produced some bullets for me to be able to test some things I've been modifying on this pistol but I'm seeing the ends of my wits coming up. I've done hours of googling as well as using the search function on this forum and haven't been able to come up with anything to help me since my problem is so specific yet so vague at the same time: It just don't wanna cast. I'll admit I'm new to casting but I've been taking it really slow and have been learning a lot. Thanks for any help anyone can provide me. If this mold is just scrap, can anyone point me to another bullet mold of higher quality with a similar bullet design being a rebated base and a flat nose?
