The Lee FCD and a faster powder
Add magnum primer?
I have better luck using magnum primers with most every Hammer bullet i have loaded.
My last test with the new Absolute hammer also did best with magnum.

Ha, after the hurricane a couple of weeks ago we got 12" in 1 week, now more coming from this one. Heading to TX in a couple of days, going the wrong direction. Of topic, carry on.

H4831 and others in that burn rate are too slow for the Absolute Hammer. Steve used RL16 with their 280 AI test rifles. Like others have stated, you need a powder in the RL16 burn rate. Steve managed to find pressure with RL16 in his testing.
I spoke with Steve and he said you won't get into trouble going with a powder that is typically used in the same bullet weight class, but the Absolutes need a faster powder than what is listed (ie; powders for the 150 gr bullets in the Nosler load manual will be too slow).

I only have 4350 and rl19. CA 1-9 barrel. Starting dose for absolute Hammer?
I have loaded a string starting at 55 grains of h4350 working up 1/2 grain at a time. Hopefully will have time this week to shoot them.

Call the hammer guys. They have stated repeatedly that you will need a faster powder than what the load manuals state and that these new bullets are only for experienced hand loaders who can read pressure signs because of the lack of load data with faster powders.
You mentioned they were hard to seat and inconsistent. what did you mean by inconsistent? Have you tried regular hammers? Reason I ask is I found the regular hammers to feel somewhat inconsistent due to the multiple canalures of the bullets but they all shot wonderfully out to 600 yards (Which is the furthest I can test them to). I did not find them hard to load though. Felt about same pressure if not a bit lighter on my press than accubonds.

Everyone using magnum primers and 1-8 twist for Hammer A?
Try magnum and standard. Chances are, magnums will give more consistent ignition. That's the case in 6 of the 7 calibers I load Hammers for.

A low engraving pressure bullet does not go faster with standard powders. In fact it will go slower because no pressure will be present with too slow of a powder. You have to find a powder that will get up to the same pressure that is created with conventional bullet loads. Then you will see the vel increase. The loading process for Absolute Hammers is no different than the load process for a wildcat cartridge that has never been loaded before. As the op has done, the best place to start is with known components for the bullet weight and collect data with that load work up. Then use that data to determine where to go from there with another powder.

Will 155 Hammer A stabilize with 1-9 barrel?

Should have a 8.5" min twist. Our 140g Absolute Hammer will run great in a 9" twist.
