No, but not for the reason(s) you might expect.I shoot IDPA and IPSC. Would a guy like me notice a difference between a normal powder thrower and a "match" quality measure with micrometer adjustment?
If you're asking about the Micro Adjustable Charge Bar for the Pro Auto Disk, it isn't there for 'match quality'.I'm using the Lee Pro Auto Disk.
No, I understand that it's not match quality. I was wondering if it would be worth $150 to buy a "match quality" powder thrower instead of using the Lee auto disc. What modifications have you needed to keep small charges consistent?If you're asking about the Micro Adjustable Charge Bar for the Pro Auto Disk, it isn't there for 'match quality'.
It is adjustable. Your current disks contain 6 fixed cavities. You do not have the ability to adjust infinitely between cavity volumes. But the Micro Adjustable Charge Bar is adjustable. That is its sole reason for being on this earth.
In my experience the Micro Adjustable is equally consistent as the fixed disks. Except when the charges get small (about 4 grains or less). Then you have to modify it to keep it consistent.
I'd go with the bolded statement. I use a Lyman measure without the micrometer adjustment and kind of wish I'd gotten the micrometer adjustment just so I could switch between caliber throw weights more quickly. I load .45 ACP, .45 Colt, 9mm, 10mm, .357 mag, and .308 and going from one to the next is time-consuming without the micrometer adjustment. If you load multiple calibers, the micro- adjustment would be the most expedient choice.I don't think you'd notice a difference. I have a little experience with a micrometer type adjustment (think it's the MicroTek brand). It came on the powder measure that came with the Dillon 650 I bought used. I have the "standard" powder measure adjustment on my other 550's.
I do not think the micrometer adjustment is any more accurate, it's just a little easier to find your previous setting(s) when you're using several different powders and/or charge weights. The normal Dillon powder drop adjustment may take a little more trial-and-error to get the weight you want, but once both are set to drop a certain charge, I think they are both equally accurate.
I'm using the Lee Pro Auto Disk. It has always kept my loads within .1 grains, but I was just curious if I was missing out on anything.
