Reloading the 300 whisper, ACC blackout

[Argonnakid]

So, I have been thinking of getting a 300 blackout upper and am wondering about reloading for it. Any thoughts on that? I'm trying to get as much info on this round before I make the leap and buy an upper.

Lot's of info here. I have dies coming next week. So I am going to start reloading it as well.

I gave all my "bad" 223 brass to a friend. These had crushed necks or bad shoulders. He was happy as a clam to get the to play with.

He made up a jig in his chop-saw to cut all the cases and then deburr/chamfers them and finally trims them. I don't think he anneals the "cheap" stuff, but, I think factory ammo is annealed.

He is shooting alot of loads with 125gr (?) bullets instead of 147gr and getting decent results.

Non-loading friend putting one together and I'll be loading them for him so I'm interested. Looks like fun, have another friend who loaded a lot of whisper subs. Still pretty new.

OK, taking the dive, just ordered dies and the newest Nosler book. The Nosler #7 is supposed to have reloading info for the 300 blackout in it. Does anyone know if any other books cover it. I like to have at least two sources to go by.

Try the Hodgdon website and their 2012 magazine/loading guide.

Good shooting.

Just flipped thru the Hodgdon reloading magazine and 300 blackout is not in there. But the one I have is Jan 2012. Did they put out a new one?

There's a whole article on p.18 of the 2012 Annual Manual, not in the data section. Go to their website as well.

The NOSLER #7 lists four powders- 4227,110,296 and Lil Gun.

It's in the website reloading guide.

Some of the powder makers have data on their sites too,,,,

Yes,I know what you mean I'm thinking about building one myself.But I am a little concerned about the accuracy ratings.I'll probably be looking for parts at the Richmond show this weekend.
