anyone loading Outlawstate 220 GI with 9" barrel AR?

[maleemi]

ATF just sent me my sbr stamp for a 9 inch 300blk (1:7 YHM) barrel. I'm still waiting on the AAC 762 sdn stamp so I installed a muzzle brake for now. First trip to the range was very encouraging, factory super and sub loads fed and grouped extremely well.

I really like the specs of the outlawstate 220 GI open tip but I can't find much info about handloading for subsonic suppressed rounds (night coyote and bobcat culling, HD and possible Eastern white tail).

Has anyone had success loading this bullet in a suppressed 9" 1:7 barrel? any power recommendations? Li'l Gun seems popular for launching subsonic 300blk heavies but I don't have any. I do have about 20 other powders I rather use if they give good results.

Also, any recommendations for die sets? I use Lee dies almost exclusively with excellent results but have read a few negatives about Lee's 300blk dies.

Best Regards,
Marcel

What powders do you have, that work in the blackout for subs?

I have the following that are listed on the sticky at the top of the "Reloading" section as possibilities for launching subsonic 300blk heavies.

Alliant 2400
IMR 4227
W296 / H110
IMR 4198

4198 is loud.

4198 is loud.

Compared to what?

You might want to try around 9.5 to 10.5 grains IMR 4227 to start off with.
I use it a lot and it always works well.
H-110 will work also but I like stick powders.

I just shot subs for the first time this last weekend . Used 220 grain Lapua HPBT match atop 9.0 grains of H110/W296 @ 2.25 COAL . in a 9-inch BCM 1:7 with an AAC SDN-6 and a H2 buffer , M16 BC , and factory gas . Functioned 100 % suppressed or not , fairly quiet , same POI @ 15 yds as my 115gr / 18 gr super load , and pushing around 1050 . Might be a good place to start.
