What is a MINIMUM load? All my manuals show are START loads. You can go lower easily, as long as bullet doesn't stick in barrel (and you need less than 1.0gn of powder to even come close to that situation).
Usually, you want loads that range from 650-725fps.
In most manuals they have a starting load , up to a maximum load or even a +P load in some.
In my 686 6" a starting load of Bullseye with a 148 HBwc gets around 710 fps.
That same load out of my J frame snub nose gets 628 fps.....
but I can get the same bullet to go just 580 fps with Trail Boss.
This is a starting load but do to the low FPS, can it be called a reduced load or a minimum load ?
In the J frame, this bullet has gotten down to 545 fps and still exited the barrel, which I would call a minimum velocity load but maybe not a safe minimum load and I would never try to see if it would clear a long 6" barrel.
With revolvers, one can really put the brakes on a bullet, for light target loads below a Factory starting target load and not get a squib but when being used in a pistol, there needs to be enough energy to work the slide and eject, which is another ball game.
I call a minimum load, one that is below a starting load but is still safe and gets good accuracy from a certain weapon that it was developed for.
I have a 150 gr FMJ target load for my 30-06 @ 2465 fps and a
180 gr "Meat saver" hunting load that starts out at 2406 fps.
These to me are a Minimum load.
