Okay, this is the only mold I have that does this, I have other RG4 molds that have no issue, I’ve tried changing the alloy, these are COWW, I’ve tried SOWW +2%, COWW, COWW +2%, Straight Lino, and various other alloys trying everything to clear this issue. I’ve heated the mold and pins thoroughly, heated the pins with a torch, cooled the alloy to where it won’t cast at all, heated it to where it frosts terrible, lubed the pins. Nothing seems to clear this out of round issue. The mold was new from NOE, did the normal clean and heat cycle 3 times, no other sprays or additives to the mold except lube on the joints and sprue plate. The solid pins seem the best but even they are out of round and the deep pins are the worst, the cup pins fall in the middle. Does anyone have any ideas before I call and bother Al for help?
Edit.. cannot seem to add pics, my file size is too large?

You said it’s a new mould. How new is it? I’ve noticed that with some moulds it takes a few casting sessions before I get decent bullets.
The only other thing that I can think of is that the handles need to be held tighter than usual. My old(er) fingers don’t squeeze as they used to so I use one of those 1.5 inch ratcheting clamps to squeeze the handles shut. It holds them closed and if you squeeze to the same “click” they’ll get held shut with the same pressure each time. It helped me get consistent results. You can buy those things for 2 or 3 bucks so if it doesn’t work you’ve still got a clamp to use.Zeus77
I wonder if the nose is still soft when it drops out of the mold? Do you know your mold temperature when you open? Have you tried letting it cool longer than usual before opening mold? With everything you have tried, I’m thinking the nose might be getting damaged (out of round) when it’s falling or releasing from the mold. I’ve not seen it before but, could it be the pins are too hot and holding heat and the nose still too hot when it shakes loose from pins? Otherwise, something in mold could be out of spec (I’ve see this with Lee). May be time to ask Al as you’ve tried all I can think of including handle fit and pressure. Good luck!

Have seen what looks like the HP is not centered but it was not getting filled out around the pin and made it look off-set.
You can look in the cavity with the sprue plate open and see if the pin looks off-set.
Would be more then happy to check it out if you would like to send it back
Will fix, replace or get you a refund it has a problem.Bullet maker, maker

Swede I have the 432 246 mould which is very similar and have no problems when the bullet frees itself from the HP pins. But when it sticks in the cavity and I try to open the handles it stretches the HP cavity in an oblong shape. It takes several sharp smacks with the mould mallet to free it.
I use a Saeco bullet sizer and make my own top punches. For HP moulds I use a top punch with a pointed or almost spitzer bullet shape . The tip goes down inside the cavity and shapes it uniformly. Applying more pressure results in a larger HP.
I am interested in what you find,please keep us posted.

Yes, I too thought I figured it out and the bullets were still soft when I was opening the mold, and no, even when I let it cool completely they still have the same issue.
Al, That may in fact be the issue. I’d rather not ship it back to you as I think it is an error on my end and not something wrong with the mold.
Any tips on fixing that? When I look at the mold empty and closed all the pins are centered, do I just need to keep my pins hotter?

Yes – heat if your friend with RG moulds
If you use a hot plate pre heat it longer and a little hotter
If you don’t use a hot plate get one.
And make sure the pins are adjusted too.

If the pins set shallow you can have problems too.Bullet maker, maker
