It's not that hard to get a gas operated gun to work with cast boolits but it can be a challenge to get an accurate load.

I cast clip-on wheel weights then water drench. I use the LEE BATOR mold then shake powder coat harbor freight red
then LEE .225 sizer and 4.0 grains of red-dot. wont cycle but I love to shoot them.very accurate for me @ 85 yds.
I use a needle nose pliers to flare case mouths.
I don’t think it’s necessarily hard but it is a consideration that non gas guns don’t have to think about. It means that you need the right powder and quantity that will still be providing gas pressure after the bullet has passed the gas port, and that requirement might fall into contradiction with other desired aspects of the load, such as accuracy or speed. Subsonics are where it does get difficult, because if you have enough gas to operate the gun, you might be pushing too fast to be subsonic.
As to why the Lyman manual states that it’s difficult, they claim it’s a challenge to get accuracy and port pressures balanced.
You can push them faster. In my old varmint rifle I was getting 1 5/8" groups at 100 yards, going 2640 fps.
The solid soft lead bullet is undoubtably the best and most satisfactory expanding bullet that has ever been designed. It invariably mushrooms perfectly, and never breaks up. With the metal base that is essential for velocities of 2000 f.s. and upwards to protect the naked base, these metal-based soft lead bullets are splendid.

Forget everything you know about loading jacketed bullets. This is a whole new ball game!
Have you been able to load up any of those rounds yet? I have also been thinking about ordering that same Arsenal mold.
I too am interested in the test results of the arsenal mold.
Lyman has another manual on loading for the AR platform. Has some cast data, for every common AR caliber, but in 223 I think its only 55gr data. Ill check tomarrow.
The Lyman AR handbook shows cast data for only 55gr boolits. Has lots of jword data in multiple weights and shapes if you start lookin for full throttle.
Only 50 yards with a scope but it functions. Was 2017 not 2015.
