Hi Roo Farmer,
I think you're probably doing pretty well at +- 0.3gr
I use a couple of Lee (not) Perfect Powder Measures for single stage. and I have a Dillon progressive.
The Dillon you have to take it as it comes but there are a few tricks , I get +- 0.4gr
With the Lee I can get +-0.1gr if I try hard
This "might" help a "little" , get anal and become a robot.
Consistancy is the trick.
Keep the hopper between 50 -75% full, strangely enough it tends to throw heavier as it emptys ?!
I have a ltttle ritual;
Pick up case, weigh it (I've got a digital scale with a single button Zero)
Case under thrower,
Throw the lever with a little force, down to the stop, ... tap,tap with a finger on the side of the drum.
Throw the lever with a little force, back up, . tap,tap with a finger on the side of the drum.
Weight the case, in speck case to loading block, out of speck ... rinse and repeat.
It's quicker to dump the load and re charge the case than trying to add/remove 0.2 gr
You quickly get into a rythm.
Prime x 100
Powder x 100
Seat x 100
Crimp x 100
It gets tedious so I rarely do more than 100 at a time, sometimes only 50
If I have a lot to do or feel lazy (which is pretty often) I'll use the Dillon.
I've done a little load development on +-0.1 increments but didn't see any real difference over 3gr on a 41-43gr 308 load of 2206H
One of my "Things to do" is spend some time behind the Crony with a heap of differnt loads.
Reloading like shooting, go as far as you want, you only have to make yourself happy.
There's always room for at least one more gun in my safe.
