Jim Downey's website clearly shows that the bullet is really irrelevant when comparing commercial ammos to how well the powder is matched to barrel length. So, you have to buy a bunch of this ammo, and, it all needs to be from one lot of ammo, so, hopefully, the rounds you put in the gun have the same powder that was in the ammunition you tested.
230 grain ball is not immune to the ammo company using a very slow burning powder, unsuitable for short barrels. What I've found is American Eagle uses a really high recoiling powder charge, that kicks about as much as common 45 Super loaded by Buffalobore, with equal bullet weight. Since I bought something like 500 or 1000 rounds, I have been able to say it's at least consistent.
I think the blessing of ball ammo is that given the bullet design, and the design of the 1911, it allows a wide variety of powders to be used, and, for the gun to still cycle.
I'm unconvinced that the major ammo companies use powders that are consistent from lot to lot, and, I'm also convinced that spending a ton of money to test fire ammo in your gun, 200 or so rounds, is in a way an oxymoron, since the next box you put in your gun might not have the same type of powder.
I will say I think the premium ammo producers are more likely to run one particular lot, with the same powder, and bullet, in large quantity, then the big 3. If you insist on getting ammunition from Hornady or Remington, I'd let someone like

do the testing to see if the ammunition you are considering is suited for your barrel length. 75 rounds should be enough to find out if that particular charge
and bullet design works in your gun.
By first checking to see if the powder is suited for short barrels, i.e. it generates full velocity in relatively short barrels, compared to the other ammunition, you have taken out one huge variable: slow burning powder not designed for short barreled guns, resulting in large amounts of unused powder, or muzzle blast, and a pressure curve that does not build aligned with the impulse required to cycle the action on a 1911.
Also be aware that things like "designed for short barrels" , "low recoil",
etc. on the outside of the box may or may not have anything to do with what's on the inside.
I remember firing some 'low recoil' .357, and, comparing it to about 10 other .357 ammos at the time, it was the heaviest recoiling of all. I guess Federal's
'low recoil' .357 was low recoil, provided you compared it to a .50 BMG...
Last, but not least:
Mas Ayoob has often said that a DA might try and use handloaded ammo to show you are some sort of nut, if used in self-defense, and, that it might be used in a powder residue test to establish distance inaccurately. That said, one might extend that argument to
'Self-Defense' ammunition.
For example: the Barnes brass bullets are excellent bullets, but, they are both expensive, and, not in common use. They are not mainstream, due to their cost. Contrast that with our local PD's 230 Grain Hydra Shocks. That's main stream, police use it, must be good, yes?
Ball has the advantage that it's VERY mainstream, though I don't think any LEO use it.
My head starts to hurt when I go down this road. My reaction really, is to find something I LIKE to shoot out of my gun, that's accurate,
and I think would work. I see no reason to spend 40 dollars a box, for 20 rounds of whiz bang SD ammo, when something else would work
nearly as well, at half the cost. In fact, I think this sort of search for the magic bullet IS evidence of sort of a fixation, and pre-meditation
with shooting people, and, I'm not much for engaging in it.
Most of my guns are loaded with something I KNOW works, or has a higher percentage chance of working for what I intend then some other ammo choice. I don't go searching for the perfect bullet, but, buy ammunition from certain well known ammunition makers that are consistent, Buffalobore, and Double Tap. This ammunition may, or may not be designed for SD. If I have to use a gun in self-defense, in my house, it's NOT going to be a common caliber SD load, nor is it going to be politically correct. It's most likely going to be what I shoot out of one of my guns designed for hunting,target shooting, or just what I've got laying around. It will be capable, by quite a bit, of doing what it's designed to do.
