Favorite handload for 300bo subs

[Wingshooter]

Looking to get started on some subsoinc 300bo.

Any favorite, quiet combos?

 

This will be fired from an 8.5" and 16"

208gr AMAX, or the new ELDX or ELD Match w/10.5-11grs of 1680, according to my chrony this coming out at just a hair over 1000fps

This loading for the AMAX is in Hornady's 9th edition book on page 386, I just used the same for the ELD's.

Also this is out of an 8.5" barrel

I've used a bunch of AA1680, while it works, it is also the loudest of the subsonic loads I've used. 2400, 4227, 5744, lil gun all have a better report. You'll have to do the work up on your gun, not all barrels are created equal. 

My my favorite quiet loads won't run an AR action but are in the realm of supressed 22, I just use them in a Handi rifle.

I'll try some 2400 to start

It's been a while since I looked, but I wanna say the 300blk forum had a lot of "recipes" in their hand loads section if you don't find a good on here.

I tried a few recipes but haven't locked in on any as I don't have a dedicated can to keep trying to get one that works right with my setup, 10.5" and 16" barrels, but I do have few in a pdf I put together for the 300Blk.  Here are a couple to try, work it down of course.

10.0gr of 2400 with a 220 SMK at 2.260 OAL

9.3gr of 4227 with a 220 SMK at 2.100 OAL

9.5 of 4227 with 208 Amax at 2.095 OAL

I'll try some of those soon. Thanks
