I think it's depends a lot on how you pull the handle.. slow-ish with a decent pause at either end of the up or down stroke..steady as she goes.

Obviously my scale isn't more accurate then .1 grain either, but if it throws nicely inbetween 6.1 and 6.3 it's decent enough.. At that point my main risk would not be powder, but foreign objects, such as a bit of corn cob stuck in a shell and raising the pressure..

But again, with .45 ACP, i believe there is plenty of margin in terms of pressure..
From what i can tell, my PM7/45 will eat +P ammo and not break a sweat.
Maybe not a good idea to make +P the steady diet, but the gun won't blow up of it does eat a box of +P

Now +P is rated 23000 PSI vs 21000 PSI for regular .45 ACP
That's +9.5% over regular.
But i'm not going for max load either, so my reloads are probably below 21000 PSI, probably a fair bit below 20000 PSI..

So overall i got at leat 15 % safety margin going on.. t would take a big ass corn cob to cause trouble....

Got 200 rounds, all with good primer all with powder that should be in the ballpark (visual check and powder check die).. So they should be reliable..
The only question left is "are they accurate and consistent enough?"

This is not self defense ammo, got factory Fiocchi for that.. All it has to do is go bang and put nice groups in.
