Took me a couple seconds to notice what you did there; just started the first cup of morning Joe.
You a funny boy. I like you. (I'll refrain from one of my favorite movie comments and not use the "you make me laugh -- I kill you last" bit 'cuz that would be rude).
Interesting loob groove innovation. Hurry up and patent it before Waksupi gloms on to it and it disappears from the market forever.

unreal!
oldpara, SIR!
You got some talent there ..
I see a new sub forum in the future - Bool-Art !!!!
I finished two of the 45 cal molds this week and just now cast up a few to check dia. and weights.
This one 231gr naked.

If you look closely you can see a little faceting on the OD of the pieces.
Sometimes I get virtually none, sometimes a little more so I try to make the diameters of the bullets such that sizing smooths it out.
I really haven'y found it to be a negative when shooting the things, even as cast, I assume that once it gets hit in the a** with 20,000lbs or more depending on the caliber, the bore and rifling do the smoothing and sizing.
The faceting is due to the curve interpolation of the older cnc controller I use. No NURBS curves for this old controller, just very short line segments sometimes imperceptible but there.
I'll dump a couple into the duxseal this weekend down cellar and see what kind of impression they make on that stuff.
I've got one more 45cal done and pinned at work and a double cav 30cal cutting over the weekend.
I'm trying to get as much done as I can before the place closes up for keeps.

Makes me want to make a mold. I don't have access to a CNC just an old lathe. Can somebody teach me how to cut a mold cherry? I know you start out making a steel "bullet" its the making it into a reamer that has me a little stumped.

"Phillips head" Now if those ain't slicker-N-Snot on a Door Knob!!
How might a body go about getting a few of those just in case I need to screw somebody,, hahaha
love those
Sparkz
Impact screw drivers.. yeah..

Back when you were trying to mirror the screw thread. Wouldn't it work to draw the block and subtract the cavity complete with threads then make a copy so you had two blocks with cavities then cut each block in half and use half of one mated with half of the other. You should not have a problem with standard threads releasing from the mold halves because they mold plastic fasteners without a problem. The part is is symmetrical about the center-line so their are no undercuts.
Dummy cartridges with Phillips bit bullets should prove popular with many people in the construction trades. Try making up a few and selling on our Swap and Sell section.
So how do those wing nuts fly? They do indeed look awesome, but "ballistically challenged". :mrgreen:
The philips head reminds me of the Devel muzzle loader bullets that were on the market a few years ago. they came and went so fast I never got to try any.
In actually putting some thought behind those lovely "soft-serve" designs... I think they could have some real potential. If you match the twist rate to the barrel you're pushing it through, you could actually gain a much higher BC just through the higher surface area. The aerodynamics of it could potentially help maintain stability much longer than a smooth-sided boolit. Add on the BT GC's I saw someone making serious headway on, and I think we have a potential match-boolit worthy of some real consideration. This could really be something, guys.
You're right!
That's basically what I did. I modeled both halves of the mold blanks, laid one on top of the other with a modeled bullet between them.
I subtracted one bullet from the bottom mold block blank and one bullet from the top mold block blank.
And as you can see "eureka" :)
My biggest obstacle was over thinking it.
The wingnuts shoot fair, I've made so many different ones I haven't really had the time to "wring out" each one.
Life always seems to get in the way of fun.
I actually modeled the philips after the screw driver, real original huh?
The one I did that was inspired by the Devel is this one in the center of the picture.
