Im jealous of you guys who have machining talents. But if I did I would probably be tempted to make things best left unmade. So, it all worked out good. Nice work BCS

That is a work of art. Great job, keep us informed on the progress. Looks like a cupped base?

Just curious to why you need venting? I have old Lyman mold that don’t have them and never experienced any issues.

Just something that I always do.

I have had venting problems before on some of my molds.

It also depends on if you are a drizzler or a packer. I am a packer...........not sure of the proper terms, but I like a little pressure on my fill.

Very nice. I can't comprehend how you put the bands on. I guess that's why I'm not a machinists!

I use a boring head on a mill.

That's good stuff, need more inventive folks like you.

Just a quick test to see if they are going to stabilize.
And they will!!.
Nice elk killing bullet.

 

[BCS]

My next test, see how the painted ones shoot.

 

[BCS]

Not tight, but not loose. could be .00025 larger. [.501.75]

And close to the lubed lead bullet.

 

[BCS]

Sized .5018 great fit for first hunting load.
Upped the charge to 90FF Goex.
Homemade 441 wax, grease lube.

 

[BCS]

The 80 grain load is a little slow, but groups well.
And
The lube is simple.

 

[BCS]

Retest with the 522 powder coated red.
80FF-felt-522 sized .50189
This is after cutting 1/2" + off the muzzle.
Really nice fit
Not as good as the 1-3 lubed lead, but a good hunting load.
