I love my 300 BO. Great cast gun for sure.
Of course you should know better than to say something is the “ultimate” on this forum. We have a few opinions!
I'm a Happy Clinger.
I've got a 16" rifle I put together, 10.5" Bear creek upper, and a Ruger American Ranch. It's got my vote....
I've never had much trouble getting it to run right, but I've pretty much started with and stuck with Shooter World Black Out for powder in the AR's. I've had good luck getting anything from 190 grain to 230 grain bullets to run subsonic. I was expecting more problems based upon what I had read online.
Loading for the bolt action Ruger is about as easy as loading for .38 Special.
Wolfdog91 I would think you should be able to get almost any .30 cal mold to work up say 175-185 grain and then only because of length and getting them to run in an AR. Nose profile plays a big part as the OAL gets longer. For my guns I size .310 yoou may be okay with .309 depending on your barrel. If you have a AR already uppers are (were) fairly inexpensive. If you buy a complete gun you have the option of using other cal. uppers with it. If I sound like a fanboy, I am. Not one of my friends who have shot mine with subs and the can didn't just start giggling after the first shot. You hear the action cycle, the brass hit the concrete and the boolit smack the target. All very distinctly.
While tracers over the head may work that is going to be a hard one to justify in court.

Exactly, I call it my garbage disposal. Got 556 brass with a boogered neck or shoulder? Make 300 blk brass out of it.
Pinch of powder and dab of lead. New primer and off to the races.
Lots of factors to consider in 'the ultimate' category but economy of brass (with right tools, made from free/cheap range brass) molds are plenty...mine eats almost every 30 Cal boolit I own. Capacity is same as 556, no special or proprietary parts, bolts or uppers- just a barrel swap.
Downrange energy for deer out to 150.
I think it's pretty awesome, some folks really balk at it....but especially today when ammo and firearms choice is in expensive or limited supply.... changing a barrel to change the game in medium game harvest is a no brainier.
300 blk makes some sense if you don't reload, but it makes all the sense if you do reload.

love the bo. Ive got 3 ars and a ruger american. With cast its a cheap shooter. Only thing cheaper is a 9mm ar. That said i only shoot super sonic and ive got a new ham'r that i think will replace the bos for deer hunting. I killed 6 deer with the bo using the 110 barnes and it did better then i expected but i still get nervous. The hamr has the same advantage with using 556 brass but has 200-300 fps more velocity which should step it up a class over the bo for actually killing and i still can shoot the same cheap cast bullets for plinking.
no 300BLK is not the ultimate cast AR caliber Actually, it's about the same as 30/30 for cast, no, not same fps. 110gr to 185gr, subs and supers from same gun and just a bit more powder & lead. I can push a 145gr cast to 2200 fps, don't need much more. I run a 170 gr FN in my AR pistol, cycles fine, 850 to 1500 fps. If you want a slower twist, order a slow twist barrel. 30Hamr cases are hard to make from 223, pretty much chambered for lighter bullets. If I need speed, 30/30 or 308W.
Whatever!
Personally I think it is one of the neatest cartridges introduced in the past 50 years. Power between the .30 Carbine and 7.62x39, fits in the AR15 with just a barrel change. Mine is a 16" 1-7" twist carbine and I use full power 110gr to 150 gr jacketed bullets mostly, but it will eat most any .308" bullet.
But I've not been satisfied with my cast bullet experience with it over weights between 113grs and 180grs. Perhaps I'll try again someday, but as it is a home defense weapon is is loaded with 110 Speer spitzers at max velocity. If I had a 1-10" or 1-12" bolt action .300BO, it would be used with cast a LOT.

hammer cases are no harder to make then BOs. Run the full length case though a 300 hamr die with a bit of lube on the neck and trim it. It is harder if you trim it first then try sizing it. I guess the way i do it is a bit more work because i run it through a 250 savage die first to expand the neck to 25 cal then go to the hamr die and form it to 30 cal. But ive done it just running it though the hamr die and might loose one case in 30. No big deal. 556 brass is cheap or free.
250 savage die first May work. You get into the shoulder/neck area with 223 modded cases.
Whatever!
There are no ars chambered in 30/30 or 308w though.
In AR platform (not AR10/SR25) there are alot of options from 25 sharps, 6.5 grend., 45 socom and 50 beowulf...but 300 blk is the easiest for cast, ease of conversion.
Like you I don't need the speed of 30/30, 308w or 3006 for my deer hunting (close in) 300 blk gives me the edge of smaller rifle, semi auto for follow ups on hogs, and more than enough penetration for all my deer hunting needs
