300 Blackout dies ?

[SWANEEDB]

What are the better die sets to use, ie-RCBS / Lee / CH4D or others?

[rockrat]

I have Redding(30/221) and Lyman. Currently use the Lyman for my 30 Apache and the Redding for my 300 BO, but going to try the Lyman with the 300 BO

I like the Lee dies, but those are the only die sets I use. Personal preference for me I guess.

[Pee Wee]

Ditto on Lee dies

My 300BO dies are Hornady. I like the inline seating, replaceable decapping pins and threaded zip spindle. When you throw in the free bullet offer, it's a pretty good deal.

I have the RCBS smallbase/AR dies for 300 BO, in case you run into some military brass the was fired from the SAW! Seems to work great so far!!

Redding 30/221 deluxe die set which gives you the seater, FL sizing die, and neck sizing die, although I seat bullets on a Vickerman in-line seater.

LEE, removed decaper, spud just happens to be right size for my cast - tight chamber.

RCBS Small Base dies and an Lyman 30 M-Die (trim about .050 off the bottom)

My Lee dies in 300 Blackout work just fine and have formed and loaded many Blackout cartridges. And what is even better they cost a lot less.

I use Redding set. I like it but then again I'm not looking for perfection in my 300bo. I'm also a fan of the sliding sleeve seaters so I may look to Hornady or Forster in my next life.

I use Lee dies for 300 AAC. They even form converted brass. I use a separate Lee factory crimp die. I LOVE 300 AAC since I can cast (Lee 312-150-2R) and reload. I built an AR specifically for it and they shoot great.

I just jumped in to the 300 blackout game, have been using Lee dies.
The Lee dies have been working good.
I do miss the bullet guide on the Hornady seating dies, but for the price I can live without it.

Lee dies and a RCBS small base size die.

I have the Lee dies but they won't correctly form .223 cases to 300 blk.

I never resolved the issue because I have a GSI trim die that correctly forms them as it trims. Once formed the Lee dies will resize to correct dimensions.

I use the HF chop saw first, then form with the Lee die. The old noses get sent to recycler and they add up fast.

I suppose every loader has a preference. I started out with Lee; had a lot of trouble with rounds that wouldn't chamber. Went to RCBS and haven't had a problem since. I have about a half dozen other sets of Lee dies that have given me no problems.

That's odd. The Lee dies form 223 to 300AAC perfectly for me. In fact, I was astonished it was that simple.

Huh? What is wrong when they form them? I've had no issues using my Lee dies to form the brass.

what 6622729 said. Using Lee to form, RCBS for everything else. Cases not chambering (finished round) is probably due to different neck wall thickness. I had to pull a couple until I found the good/bad brass listing on 300blktalk, since then they all fit.
