Suggestions for Turret-Mounted Powder Measure?

[shooter1]

Haven't use the auto disk to charge rifle cases, but I understand you need to use stacked disks to get the volume you want. I have the adjustable Lee powder bar. It doesn't work well with small charges of flake powder, can't say how it will work on the larger charges.

Yeah, that seems to be the consensus that the disks don't meter large flake powders well. I'll try to avoid those but in these times, the large flake powders are often the only ones left in the powder safe at the reloading stores at two ranges I go to. I've only seen powder on an actual shelf at an actual FFL. I've used American select and get accurate 124gr copper plated 9mm bullets using 4.8 grains +/- 0.1 grain. My brother picked up two pounds of Unique and he has enough powder for about 3,000 147gr 9mm rounds. I figure if I ever have to load this type of powder, I'll use the disk to charge them and immediately take the shell case out and dump it on my powder pan to weigh it. If the charge is good, I can just put the case in my loading block and recharge it using my lyman funnel.



I'm well aware that the double-disk set is needed for charges for .308 and such, but I'm wondering how many grains of Varget the largest disk can hold, without purchasing the double-disk. I'm not too cheap to order the double-disk ($10 is nothing compared to what us reloaders spend on our addiction, lol). I'm just thinking that if the largest disk can hold 24 grains or so, I should be able to load up my 69 gr. Nosler HPBT on it.

Anyone ever tested to see how many grains of certain rifle powders, the largest disk that comes standard spits out?

Also, is there anything I should do to the Pro Auto disk before using it (i.e. spraying graphite or something else in the hopper to minimize static electricity)? Any little tricks of the trade to minimize fine ball powder leakage?

You will need to weigh one cc (or calculate to one cc from a larger quantity's weight) of the powder(s) in question to get a conversion factor (grains per cc).

Maximum CC of single disks = 1.57

[Volume cc (1.57)] divided by [grains per cc] = grains of that powder yielded by a 1.57 disk aperture

Thanks for that. I've also seen the PDF of the instructions that come with the measure. They also give an easy formula to follow in order to calculate your own VMD for a specific powder they do not have listed. I was just wondering if anyone had put Varget in the 1.57 disk and seen how much powder is dispensed.

UPDATE:

I am dam pleased with the Lee Pro Auto Disk Powder Measure! I've decided to use the 0.3cc disk for CFE Pistol powder and 147 gr Copper plated round nose from Xtreme. It consistently throws exactly 3.9 grains 80% of the time. The other 20% of the time it throws 3.8 grains...I can definitely live with that!

I'm using a very fine ball powder so there is a tiny bit of leaking, very tiny, after about 50-75 rounds, not that big of a deal. Besides, there are some great you tube videos that show exactly where you have to file down to make the hopper sit flush and what equipment to use to file it - should take about 5 minutes and virtually eliminate leaking. I'm happy with this Lee product and will recommend it.

I'm using a Lyman T Mag Turret Press that I bought used on Craiglist, from a fellow Calguns member that encouraged me to join. I think the fact that I'm on a turret press is helping the consistency. Every time I turn the turret, it helps the powder settle. That to me is better than having to tap an RCBS uniflow or similar the same way every time to get consistency. Having the case mouth flared and charge thrown with one pull of the lever is pretty nice.

The Lee Pro Auto Disk is a real value in my book. I haven't tried to use mine with rifle powders, but it just might work with 5.56 with the low charge weights without the Double Disk kit. I use the Dillon measures for rifle at present, but have three of the LPAD measures mounted on tool heads for pistol loading. I haven't used my Uniflow or Perfect measures in quite some time.

I've only been reloading about 6 months so the Lee Pro Autodisk is the only measure I've used. I could never understand what all the complaints were about. I've only used a handfull of powders, but never had any leakage. It is as consistant as the sun coming up in the morning. True, with the disks you might not be able to get within .1 of what you want but that's not been an issue with me. Glad you experiances have been good.
