The Ongoing Whisper Bullet Project
Most of yall have seen the 5 Cavity bullet mold that I made for .30 caliber bullets.
I am still looking for perfection and this will be a thread dedicated to just that. I molded up some bullets that weighed 275 grains and lubricated them with Moly Disulfide because they need to have something on them for lube since they didn't have any lube grooves. I did this to keep from gunking up the Form 1 suppressor that I use on the .300 Whisper Remington700 that I built.
I figured that the heavier bullets would hit harder, putting the energy level on par with that of a .44 magnum. This is from an extremely accurate rifle that is very quiet.
Sounded good in theory anyway.
Loading the bullets into a case however, wasn't as easy as it should have been. Due to the square base of the bullet, shoving them into a case resulted in shaving some lead, leaving a small ring of lead around the neck. Not good for any kind of consistency, and accuracy is all about that.
So, I thought, I have several dies with case belling adjustments, that slight bell the mouth of the case, I'll see if I can get something to work. Wrong. Nothing was even close. Since the .300 case is basically just a .223 chopped off at the neck and necked down to .30 caliber, nothing I had worked.
So, I had to make one. I used a case for the guide and pretty much copied some of the more popular patterns out there. The die centers the very base of the bullet and has an adjustable stem that enters into the case mouth to bell it every so slightly. Here is a picture of the die with a case in it. The bell pilot is sized to .307 to insure perfect alignment.

This next picture shows the bell stem. It really doesn't take much to allow the lead bullets to slip right in without shaving lead. Having done a few dozen of them tonight, so far I am very happy with the results. Every loaded bullet looks great with no lead shaving that is evident.
Hopefully sometime soon, I be able to shoot these things through my suppressed rifle to see how they pan out. If they shoot as good as they look I'll be happy.
I haven't decided how to finish this die yet. I can either put a black oxide finish on it, or blue it using cold blue. Heres a picture of the whole assembly.
