Bullet mold not filling out

So just bought two new baco paper patch money molds 444/525 & 444/540 the 525 fills out no problem the 540 is sporadic I've tried every thing to troubleshoot adjusting sprue plate , tension of mold closing , temperature 800-900 degrees I have probably 50 molds and this is the only one I have trouble with I even have the exact same mold from baco and it works great I know he had to switch metal supplier so wondering if that's the issue ?

Not sure why the time say 6:11 pm I sent this in the morning?

You have to choose your time zone, mine was off 15 hrs till Lew told me what to do. Go to profile, then preferences, then scroll down to time zone and choose one that’s same as yours. Hope I got that right.

Found it thanks !

Did you get this ironed out?

Are you Ladle Casting? If so, Have you tried Compression?

Bottom pour like you yes I've tried every thing very puzzling I spoke to baco they said to send it back for Jim to check. Can we upload pics on here ?

Yes, you can post pics

I just tried to upload pic dif it go thru ?

It looks to me like the Mold is not Hot enough, Do they get better the more you Cast?

Try this, and I’ll bet it fixes it

With the Mold CLOSED, Dip the Bottom of the Mold Blocks in the Molten Lead/Alloy and let them Soak for 7-8 Minutes, Use a Timer so you know exactly how long. I know it gets old Sitting there Holding the Mold that long, But that is the way i did it for Years with STELLAR results, I switched to the 2 Torches about a year ago and it works Far & away better

By your pictures, I am fairly confident it’s a Heat issue, I say the Mold is not up to temp.

After letting the Bottom of the Mold Blocks soak in the Molten Lead/Alloy, And you Cast your First bullet, REMEMBER to NOT open the Mold to Soon or you will make a Mess if the Bullet has not completely Hardened up, When you see the Sprue Solidify, Wait another 45 Seconds or so before opening the Mold

What you want to do is get the Mold slightly over-heated, and as you cast 4 to 5 Bullets the Mold will Cool down and enter “The Zone” This is where you will get OPTIMUM Fill out. I do this With the Sprue Plate left open, Quickly Cast 4 to 5 Bullets and dump them as quick as they harden good (about 5-6 Seconds after the Top Solidifies) Now Swing the Sprue Plate Closed and Start Keeping

i'm already casting from 820-900 degrees i pre heat my mold like all my other molds and it always works fine thats what really puzzling i know he had to get his mold blocks from a different supplier so not sure if thats it ?

If you follow the advice i gave above i am Confident your problem will go away.

Your new BACO Mold Came with a “Proof Bullet” Didn’t it? I can assure you That Bullet was cast with the Mold at the Correct Temperature

yes they always come with one i actually cast a few that were perfect then they just went south from there.

If you continue to have problems give BACO a call. I bet they will help you out.

I did call them they want me to send it back but I guess I'll try it one more time on sunday

Definitely give it another try When i say let the Mold soak for 7-8 Minutes i mean Just that, I have timed it MANY times. Use a Cheap kitchen Timer or similar so you can be exact. My Iron/Steel Accurate Molds take a Full 8 Minute soak, My BACO Molds are right in that same time, at least 7 Full Minutes. Dunk the Bottom of the Mold Halves about 1/4 the way up, Push the timer button and Patiently wait. This is the reason i went to the 2 Torch method, It takes about 2-1/2 Minutes to accomplish the same thing.

The above is for an Iron/Steel Mold, I can’t speak for Aluminum as i rarely use them anymore

If you follow the above, this is what you can get

i'll try it ut it will be the only mold i need to do that even my other baco's

I have to do the above with EVERY Mold i own, it is the ONLY way to get optimum Fill out. You might think that your others are filling out fine, But i can assure you they aren’t.

In short, If you and i were casting from the Same Lead Pot, and you Cast 20 Bullets using your method, and then i grabbed your Mold and i casted 20 Bullets using my Method i can GAURANTEE you that my 20 Bullets will be Heavier, simply because i am getting optimum Fill out and you are not

How do you explain I'm getting the correct weight?

If my memory is correct thise 750's I sent you were correct weight ?

You aren’t, you might think you are, but I assure you that you’re not

Here are a few of the 750s that you sent me (i just now went and dug them out of my Scrap lead pile) These were so far out that i didn’t even bother with them, these are 10 FULL Grains apart which is a HUGE Variance. For my strict standards these are totally unacceptable, I Cast these BIG Bullets to no more than 1 Grain of eachother, And i do so by the method i am trying to teach you above. If you will listen to me and follow what i am trying to teach you, You will be casting the same HIGH Quality Bullets that i am

Just because I ask questions doesn't mean I'm not listening I appreciate your help and plan on trying your method. Hum I thought you said those 750's were good ? To be honest I didnt weigh them before I sent them that was my bad just too busy and forgot. When I cast my pp bullets they are spot on I might get 4 or 5 I have to throw back but enough talk about it I'll try it asap and get back at ya. Merry Christmas to you!!

No offense whatsoever, I am genuinely trying to help ya Lou! I didn’t want to hurt your feelings about your Casting with the 750s, I was able to keep about 15 of them that were reasonably close in Weight, these ones i Culled back due to them being so far off in weight
