My experience is that you can get better accuracy with 120/130 grain jacketed bullets. The thing is, they cost more too. Using lead bullets may open up your groups but it makes for more trigger time.

The only problem I have found with lead that is too soft is the violent transition from magazine to chamber. Softer lead, even if PC'd tends to get damage of one type or the other as it goes into the chamber. Other than that, I have shot soft lead PC's in my 30-06 bolt gun to 2600FPS with no issues and excellent accuracy.
I should have clarified that I meant subsonic heavy bullets.I settled with 3-5 moa pinging steel at 100yd using imr4227, powdercoated, sized 309/160 grain GC lee cast, out of a 7.5" bear creek arsenal upper.
Definitely room for improvement, but it's good enough for general plinking ammo at the range.

I'm really starting to think that something like a 350 legend would be better for subsonic AR15 stuff.
Finally got pics of my subsonic powder coated cast @ 100 yards
Had my target set out at 100 yards to check my Muzzzle loader and shot 5 of my powder coated cast Bullets before putting up steel
10.5” Faxon barrel and home made form 1 suppressor shooting Lee 309-230 mold Powder coated gas checked with 9gr H110
Grouping exceeds my expectations.
For steel
Nice thing is that with my electronic muffs, it’s not so loud that they cut out when I shoot and the sound of the steel is pretty loud to me and noticeable .

Does it cycle those or are you single loading? That's probably the best group I've seen for cast subsonic 300 blackout out of an AR.
Out of curiosity trying single loading not from a magazine and shoot some groups.
Curious what (4) 32lb bars of pure lead is worth. 128lbs total. Thanks
