This sounds like a failure to feed and may be attributable to the shape of the Hornady subs vs your feed ramps.  Before buying a bunch of parts, try some 220 grain FMJ subs and see if these feed.  If they do but you are getting failure to eject, overgassing, or other issues, then buy an adjustable gas block, springs, buffers, etc.

I shoot a lot of suppressed sub and supersonic 300 BLK. They sell it as a round with the ability to shoot super and subs interchangeably.  In reality you need to do some load development to find 2 rounds that a given gun will run reliably with a simple mag swap.  Mine is 220 grain FMJ with 11.0 grains of 1680 for subs, and 125 grain TNT and 19.0 grains of 'Lil Gun for supers.

Thank you, will do.  I’ll have to get a 10 round one thanks to this commie state, ordered an h2 to check that box.

Both my 300 ar will not reliably cycle the 208 hornady black ammo but will cycle the 190 grain. They love the remington 220 subs. one is a home build the other is a daniel defense.

Adjustable gas blocks don't allow more gas to pass than a standard gas block.

well, I’ve had a few people tell me that might fix it?  It was only $37 on midway so I figure it’s worth a shot?  I’m not a gun guy so this all sucks, was hoping to slap it all together with the can and go.  Nobody told me I might have issues, lol.

If an H2 gets you closer to operational, you have an even heavier buffer than an H2. Did you see the weight references  I posted earlier?

I haven’t pulled my spring out yet, but it seems my action is too fast?  Kinda wish I could just drop off the damn thing to someone to fix but not sure about laws anymore, can’t keep up with the BS that gets passed.

They do if you open up the gas port.

Which adjustable gas blocks allow more gas to pass through than standard gas blocks?

None!

You are correct!
Adjustable gas blocks only adjust one way, a standard gas block in already by default wide open.
Only 2 defining forces sacrificed themselves for you:
The American Soldier and Jesus Christ. One died for your freedom, the other for your soul.

My rock,
He trains my hands for war and my fingers for battle.

Cleaned, and installed my h2 buffer, didn’t even eject the spent shell and in one shot, smashed the spent shell.  Going for an H3 next with the advise of a gun guy at Big J’s in orting.  Frustrating but he thinks the h3 will be it.

So your bolt carrier group didn't move enough to eject the case and crushed it. Using a heavier buffer isn't going to remedy that.
