When you say back off, that is the part i'm not getting i think.
Everyone casually says "with proper relief" or "relieved".
I Have been having trouble getting the proper relief on the form. if it...

I like your thinking Ascast.
I to hate the mold numbering systems some manufacturers use.
In my opinion there should be numbers stamped or CNC'd on the mold and they should be the Size, weight, and...

Thanks for all the replies. I have looked at the competition. I guess the fact that they are still around should say their prices are set appropriately for their product / customer service.

Always...

Thanks for the comments. As usual this forum is the best thing since .... gunpowder?

Thanks for the tips, i'm using 2 different size drill bits to remove most of the material but a form drill would be allot better.

Update:
Cutters made for Keith style traditional lube groove and powder coat 300 blackout.
I was successful cutting mold cavities on the CNC mill but it was taking so long that I abandoned that for...

I wanted to get peoples opinion on mold pricing.
I am ramping up to make bullet molds right now and I find it is pretty time intensive.
I often ask ... am i going to really make any money doing...

Got a cutter made for .308 - .312 today. turns out the laws of physics won't let the nose profile fit on a cutter as small as .200 that would cut a .223 through .454 so 1 cutter for all calibers just...

I don't think there are enough primers in your picture Beagle :)
Impressive.

Thanks for the comments guys. For me it has been a toss up between aluminum and Brass. I have read about tinning problems with them but it seems easily fixed with some bees wax. I will stick to the...

I am starting this post to see what people's opinions are on mold material.
I am currently working on some molds with 6061 Aluminum but want to get a good idea of what the other metals offer us....

Update time:
It is well before summer and project is back in the works.
Milling machine is fixed and dead on the money now. (only had to tare the whole X axis apart and replace the screw, make new...

Allot of gunsmith lathes are around 10 or 12 swing with 36" between centers. 1.5" through hole should accommodate but as you well know most barrels aren't that large.
I have had good luck as well...

I use non stick aluminum foil from Walmart, works like a champ.

thats what i got from it too Schrag, I have had that issue as well. good to know im not alone :P I always wondered if a factory crimp die could remove the "bullet bulge" you sometimes see in the case...

I think most of us have an ACE within range. Very nice to know we can get them there. Thanks for the info :)

Sorry no updates. The inaccuracy of the milling machine has me working on machine tools again. I hope to get back to this project before summer. A friend and i are building a couple of larger lathes...

I just wanted to give an update on this. I havent forgotten about this just yet. Something about working a full day and then coming home and working 8 to 10 hours drags you down rather quickly. I...

I got the machine partially putback together, still have to make a new mount for the stepper motor. Hopefully can do the testing this weekend and see if i got the accuracy i need.
I'll post an...

I just wanted to give an update: i am replacing part of my machine. Parts are on order and this should take care of the accuracy issues. I should be able to have parts installed and do some testing...

How much is too much? Just curiouse. If you want to see lee make this mold you may be wanting to spend 19.99 ish? If there is enough interest in this mold i could do a run of them sometime. Id have...

After tinkering for a bit and taking into consideration all of your comments I have come to the conclusion that the most versatile way to do the cavities is either on the mill with Interpolation or...

Hey guys i have a quick update for you all.
After the maintenence on my machine i was calibrating and discovered i have an issue in my x axis.
The short story is i wont be doing any helical...

I totally agree. If you have been following along with this thread you will have seen that I state just that in post #20. I will not take any payment until I am Happy with the way a mold comes out. I...
