Dispensing powder for saving time.

[rjtfroggy]

When reloading the last thing I worry about is saving time. Thats when mistakes happen.
I run an original RCBS dispenser (made by Pact) it is usually +/- 0.1 on the original electronic scale so I set load accordingly and weigh on balance beam before dropping into case.
Shooting short range BR one or two kernels doesn't matter all that much.

I actually have (on current loan to a friend) an original Pact infra red dispenser to scale trickler. It’s pretty awesome - even today.

I have a new in box (well 2 boxes) unit but when I tested it last the scale had some drift problems, how long do you let the scale warm up before you use it?

I left mine on quite a bit, it was a decent set up, accurate to about .1 gr, if I had a high volume of cases to load I would probably look into the V-4

I just turn it on, set it to run then calibrate with dispenser (twice) then set the load and run with it, make any adjustments and run it.

Thanks guys, ill pull her out and see what we can do

I would turn it on about an hour before loading. It did need some time to settle. As others stated, I found it accurate to .1 or so. I loaded many BR rounds for 100 yd use with it and had great success. I also had to run it through a power conditioner at my old house.

Is it faster than 2 chargemasters running separately?
Not sure that 2 months is an accurate picture at this point, but if true, certainly helps the V4 proposition.

I watched some videos on this subject yesterday. 42-44 grains of powder took 20-25 seconds with chargemasters and the autotrickler did it in 12-15. The autotricker was on med-slow which means it is capable of going faster.

Except when slow devices allow distraction or a break in rhythm, which can lead to mistakes. My current setup is easily fast enough to keep up with my seating and measuring CBTO.

After the A&D Fx120 and V3 or V4 or 5,6
Whatever version your running there is just no way id ever go back to doing it the old way…im smiling every time i load a100 cases in under s hour.

My V4 is faster than my Chargemaster. And I don't think it's 9 months anymore on the wait. I think it's more like 2 months.....

My buddy just got notice his was ready to ship (haven't heard that it had shipped, but that was Sunday.) Ordered in February.

Another friend ordered substantially later; don't recall when his anticipated ship date is (far enough out that nobody's holding their breath.)

Hi,
When I am reloading to slowest process is dispensing powder, sometimes I have 300 rounds to load. I currently have 1 RCBS Chargemaster. I am not sure if i should get another RCBS or if there is one unit that will speed up the process. I am dispensing H4350 for a 6.5 creedmore. I tried using my Harrell Precision with this H4350 and I was unsuccessful as well. The Harrel does work well with ball powder. If anyone has any suggestions it would be great.

what is the ammo for?

We can spend as much as we want to get as precise as possible for all things reloading. That said I just finished loading using a CM for a match this weekend. Because it only takes a few extra seconds I reweigh them as I go along, and all 70 were within +/-0.05gr. On those that are at the extreme I add/remove kernels to tighted up a bit more. I optimized the parameters and use a small diameter insert, as trickling a small increment is more important than the display on this unit. Note I said display, because this appears to be a stand alone display vs part of the A/D converter for the strain gauge, which can explain why the resolution achieved when loading is much better than the 0.1 on the display. CM is not the best unit available, but it meets my needs so far.

For those who have 0.02gr Accuracy vs say 0.1gr or 0.05 gr accuracy, do you know what is the difference in MV vs SD if you shot 10 shots from each load?

I just checked. We have a few available in the next shipment that is coming in. We are currently running about 8 weeks on V4s.

I don't compete for SD or ES, I compete for group and score. So I don't chronograph ten-shot groups, yet I have shot several 10-shot groups under 5" at 1000 yds. Also, ES/SD isn't a direct correlation to group size--I do sometimes chrono the 4-5 three-shot group round robin tuning "ladders" we test with. I know this is hard to reconcile for guys who think data can tell us everything.

We do fine tuning in .1 grain increments with 6BRAs, and sometimes we will even split that .1 grain. In the 300 SAUM IMP and 300 WSM, it's .2 grain tuning and then .2 gets split. We see those small changes on target so we need a very accurate scale.

I don't think such small changes can be seen on target for anything other than a BR rifle, or maybe an F-Open rifle, during testing. We usually test in excellent conditions so we can see such small changes.

Some will try to calculate the effect of a kernel of powder this way. Let's say we are shooting small capacity case like the 6BRA and our load is 31 grains on H4895. Let's say our velocity is 3000 fps. So 3000/31 gives us 96.77 fps per grain. Assuming each kernel weighs .02 grains that makes 50 kernels per grain. 96.77/50 = 1.935 fps per kernel.

If that were true, then .02 grain accuracy vs .1 grain accuracy would be about a 10 fps difference. However, the relationship between powder charge and velocity isn't linear, and sometimes slightly higher charges produce slightly lower velocities.

So the primary reason to aim for .02 grain accuracy outside of BR is simply to be as precise as we can in all our loading practices. With .02 grain accuracy we won't have to question if our powder charging process is contributing to bad groups.

Your 6.5 CM can use Sta-Ball 6.5.

With that powder, and any good quality powder measure, you don't need to weigh individual charges.

The second fastest way is to drop the powder to about a grain under, and trickle up. This is faster than any electronic dispenser, as fast as three Chargemasters in series can do.

More Chargemasters could go faster, but more units equals more simultaneous over or under charges and multiple differing drifts.

And all thos extra drinking straws, or whatever other ridiculous hacks such a laughably expensive paperweight might need to improve it's function.

I don't know that throwing a charge a grain under and then manually trickling up is faster than a V4. The V4 does the same thing. It throws the bulk of the powder from the big tube and then trickles the rest in with the small tube. While it's doing that you can seat a bullet, so I think the overall process is faster with a V4.

Dump the initial charge under but close to final charge with something like a Lee PPM. Then, trickle with the Chargemaster on auto-dispense for the last few .10s of a grain.

I dispense a powder for say 6mmCrdM, 41.8gr of H4350 using FA intelidrop, pick up the powder drop it into the case, put the pan/funnel back on the scale. Take a fresh 108gr ELDM seat it and when I turn back to look at the FA Intel-D, the charge is ready.
