Never got to shoot matches with the Government Model M1911, just fix them, when I was in the Navy.
Ammo was the standard Ball 230gr FML, that would fall between 760 to 850fps , in the old war horses that we had.
Just had to put up with the standard 16 pound spring unless it got old with use and got down to 14 pounds.
We knew, if the ejected cases landing at three feet or six feet from the shooter, when the springs needed to be retired.
Back then, only time at the range was the only way to improve scores.
Today with the Variable style springs and custom parts at your use and tight bushings, a ACP can cut its groups in half, without even reloading with different powders and components.
The 45 ACP has come a long way, from when I had the pleasure of having them laying on the work bench, in front of me.
No matter what load you come up with to shoot your matches with.....
Just know that you are a winner, just having that fabulous weapon, to enjoy.
Stay Safe.
