Making 300BLK Brass

[scap99]

Dillon just shipped my parts to convert my XL650, this is getting ready to be a lot more fun.

Here's a pic of the transformation from 5.56 to 300BLK



I've chopped, polished, necked, trimmed, and swaged close to a thousand, and have my last batch in the tumbler, now.

No more single staging it for this one, time to fill an ammo can!!

Sweet!

I assume you have to turn the necks also (or maybe you have done that already).

Nice!!
How long did it take you to cut and form all of that brass?!?

I've been doing the same but with -06 based brass and converting them to 8mm Mauser. Only thing I want to change is the head stamp some how, preferably to represent the new caliber, but at least just a mark through of the old caliber. I'm finicky about people shooting my firearms because I'm worried they'll pick up an old -06 case that's converted and try to chamber it in the wrong gun (some people are persistent enough to force it to work).

Designed to not need neck turning.

I can cut them down quick, sizing is simple, trimming is the pain. I use a 3/8" electric drill on high speed and the Little Crow Worlds Finest Trimmer.
Trimmer is awesome, but the case is so short that it makes it tough to hold.

What about annealing? I was going to ship mine off to a guy that converts for $.08 per round plus $.03 for annealing. Is it necessary?

I'm not gonna sweat it. Hoping that by the time these necks start to fail, I'll either have an annealer or factory brass will be avail.

What annealer? And nice semi dodge on the question lol.

I take it from your response it's a good idea. Remember, I'm brand new in this reload game.

This guy makes top notch products.

Annealing isn't a bad idea, but you can get several reloads without it.

Pliers work well for that.

Gloved fingers work better.

I guessed you had something figured out after that many cases.

Very true.
Plastic jaw protectors on a set of pliers would be awesome.

Have you tried the Lee case length trimmer? It's a breeze on other rounds. I bought one, but have not had the occasion to use it yet. It's really easy to hold using the Lee drill chuck.

I was curious how well the Crow's WFT worked. It gets good reviews and I've watched the video demos of it. I thin probably the goved hand like you said will work best. Utilizing a tool that has to be put on or a case put in would be even more tedious and severely slow the pace down. Though I'm curious if it would work, how about some black fuel hose with a plug (so the case doesn't slip in too far). Slide a case in the hose, use the hose to hold the case and spin it for a little longer handle, pull the case out and do the next one. The tension wll have to be just right though. Might be more trouble than it's worth if you aren't losing fingers lol

They make vise grip pliars that are designed for welding tubing together...the jaws have tubing clamps. Just a thought, might be a good gripping platform....

making 300 blkout is no big deal. Bought a little chop saw from hf cut off the necks chuck into my triming lathe.. done.

Is this a full size chop saw or an angle grinder on a stand setup?

I use the lee. I'll chuck the cutter/length gauge in a drill press and lower it down on a piece of mild steel plate that I'm holding the case against. The gauge contacts the plate and I just hang onto the case. No chucking and takes 10 seconds or less per case. I use gloves to hold the case, as they'll tend to want to spin sometimes, especially after a rough initial trim.

I've got a few different caliber tool heads for my Giraud that make trimming a breeze, but no 300...yet...
