300 AAC aka 300 Blackout

[harrysmith]

Does anyone on here load the above caliber? I'm looking for some practical advice rather than googling or published data.
I've got 110gr and 165gr copper jacketed heads. Powder wise I've got a choice of H110, Bullseye or Herco, (all pistol) as I've heard this round prefers a fast burning pistol powder. Up to now I've just used factory rounds but it's expensive that way. I've got plenty of primed cases and a Lee Turret autoprimer and all dies, just ready to go. I'm not bothered about subsonic rounds either.

H110 would be my choice.
Bullseye might cause stuck bullets.

That's great.
I should have mentioned I'm also looking for advice on powder charges with those bullet sizes.

I use N110 and N120,
150gn Lapua Lockbase Viht N120 9.3gn = 1040 fps, very quiet & 19.6gn N140 = 2018 fps and shoots quite flat,

200gn Lapua FMJBT with N120 @ 10.2 - 15.7 go between 1037 & 1506

cracking round its my new favourite, it doesn't beat you up like my 308 and ''STILL'' destroys things quietly

Avoid Bullseye and Herco unless you want to practice clearing squibs

H110 would be a good way to go. CFE Blk should give good results too.

Gordons Reloading Tool will be your friend.

Bullseye can be good for downloads, but I would only use cast bullets, not jacketed. I tend to use 4.5 grains in 7.62x39 and .303.
