Clean that mold again, use alcohol or brake cleaner. And turn the heat up some more.

You also need to heat your mold up. I heat mine with a Mr. Torch that I purchased from Tractor Supply for a couple of minutes rotating the mold and just cast away. By heating up the mold eliminates wrinkles in the mold etc. I also have my Lee pot set so the temperature is 800 degrees.
I found a video that a former member created on how he casts. I hope this helps.

A high temp thermometer is your friend. Get one. They're cheap. Yiu got good advice above. Clean your mold good and smoke it. Heat your mold up once the lead gets to about 750*. Open the sprue and fill the mold up about 5 times and dump the bullets as soon as the lead solidifies. Not before or you'll have a mess. This should get the mold up to temp. You may get one or 2 fills with wrinkles but after that they should be fine.
Note if you get holes in the bottom of your bullets the lead isn't hot enough.

Only problem I've had is wrinkles, never before had this much trouble think it was around 700, I'll try higher heat, it's first time useing this pot.

Only when the mold/lead is not hot enough.Get the lead close to 800 degrees. Ehatcsettydobyou have your lead pot at? I have mine set between 7-8. But like Bronko said get a Lead Thermometer.

Now you're casting a big bullet. The mold has to be hot. Either your lead or your mold is not hot enough and I'm suspecting its the mold.

I have several Accurate molds but, like bronko pointed out, bigger molds(over 400) need a little more heat. Both the mold and the lead. I have a 535 gr .45 mold that just likes to be really hot. I have the Lee 420 bottom pour set at 6.5 and that gets me to 825* after about 2 hours of heating. So all pots are different. I pre heat the molds with a propane torch then i like to run a dozen fill&dumps before i start looking at bullets.

It is a help ,with pure crank it up all the way I also use a hot plate (cheap) and I set it on 5 (the hot plate) along with my ladle as bottom pours on conicals /large 530 gr ellipticals fill out best with compression casting . So while your taking a 5min break flux your lead and all will be well ,unless you decide to skip this advice cause then you'll be back asking why (really) /Ed

If using a Ladle, I leave it on top of the lead as its melting if you do not have a Hot Plate. You don't want to put a cold Ladle into HOT Lead. Talk about HOT SPLATTER!

Just curious as to the diameter of your bullets. I ordered my mold so they measure between 504-504.5. Reason being if a person wanted me to make some say for their 504 White ML, I can just cast and lube them and send them off. For my TC Renegade I purchased a Lee .501 sizing die and they fit perfectly.
