Dillon Progressive powder throw consistency??

[Calplinker]

Wondering how accurate and consistent your powder throws are with a Dillon progressive.

Been loading up some 9mm on my 550B and decided to check out the consistency on my new GemPro 250 digital scale.

I've loaded around 750 rounds so far and shot about 300 of them.

Recipe is 4 grains of Bullseye pushing a 124 grain Extreme RN bullet.

I filled up about 25-30 cases and measured each one, getting results from 4.02-4.08 grains.

This is a lot more consistent than I expected, so I'm wondering if this holds true for rifle rounds as I'm about to load up some .223 and .308.

To be honest, this impressed the heck out of me. I sort of figured that since the Dillon dispenses by volume that the range would be .5 of a grain or so, which is fine for plinking but scaled up to .308 volumes, not that great.

What are you folks getting with your Dillon progressives, particularly for larger throws such as for a .308????

in my experience with bullseye its pretty spot on after the innards have had a pound of powder cycled through i load my 45acp lead with 4.5 bullseye

and bullseye is not easy to meter

ball powders like 748 work even better

Stick powders sometimes bridge meaning they can get stuck while dropping. But overall I think the Dillon powder measure is one of the best out there. There are tutorials online if you are interested in making it even more accurate. You pretty much polish the insides.

Ramshot TAC meters really well. So does Win 748.

That's good info. This one may in fact be polished through 30 years of use. I bought the press used from the original owner who used the same powder measure and bars for all these years. He also has the springs wrapped around the back to return the bar for the next load. He explained how this works and it seemed wise, so I left it as is.

How's the precision of the scale you used to weigh them? +/- .06 grains isn't much. A slight shift in where the load is placed on the scale can do more than that depending on the scale.

Scale is GemPro 250. Accurate to .02 grains

I'm really curious about the consistency you folks are seeing on higher volume loads such as .308?

What'cha getting?

308 and 223 with ball powder is within .2 grains for me when you have a consistent stroke. I've never had 308 more than .4 variance and 223 is no more than .2 variance. Remember, this is ball powder. Stick is a different story....

Mine is pretty consistent as well. Knock on wood.

On my 650 with IMR4895 at 42gr. I'm +\- .2
That's only if I am steady and consistent with my pulls.
Just plowing through, as much as 0.4.

Using HP38/W231 it is accurate to within 0.02

For Solo 1000 and TiteGroup my Square Deal and 550 both throw +/-.1 grains measured on a Gemini 20 (+/-.015 grains)
