It's something...
.5cc approximately equals 8 grains, Mike. Just different units of measurement. Kinda' like yards vs meters.
I have a conversion chart that I reference. It came from Lee. There are certain powders that you cannot use with the dippers.
I do not like the beam scale, and if I decide I want to do more of my own load developing, I'll end up with a digital.
In this powder, .5cc or 8 grains is a starting load, so there seems to be a bit of room for error.

P.S. Got a Lee book sitting right here, on loan from the gunshop. J.S.
I appreciate it folks.
I've read about the automatic powder feeders being off by as much as .5grn between charges as well, and that's one reason I really didn't look seriously at them.
It's hard to tell from the photos of the ammo. Are you using a taper crimp?
If you're only using these for target practice, you might consider backing off a bit. 230s at 980 is pretty swift, and if shot in any volume, pretty hard on you and your pistol. You might look for a load that pushes around ~725 fps. You'll save on powder and yourself. 4.5 grs of Winchester 231 or 4.0 grs of Hogdon Titegroup would get you there. 3.6 grs of Hogdon Clays would be sweet.
Hello,
Where did you get this? I would guess I'm running 800fps or a bit less - the charge I'm using is well below maximum.
I think I may have said something about factory XTP FPD ammo being run at 950fps or so, but they're +P.
I'm running below minimum, a target charge.
Or did I make a typo?
Thanks,
Josh <><
I'm sorry, I misunderstood. I thought that you said that your loads were doing 950. I get it now.
But...this brings us to another important point - get a chronograph. All of the load data in the world won't tell you what your ammo is really doing, but a chrono will. Don't guess - know.
Old Syko,
No, the correlation between volume and weight was not lost on me. I would expect a totally different weight with extruded powder, and another one with flake.

Josh You really don't get my point! I'm not talking about a volume to weight difference between different powders. Like I said, you will find weight to volume differences from one lot number to the next of the same powder. In your case AA#5. Don't count on that dipper holding the same amount from one can of powder to the next without checking weights with a scale.
