Good posts! The loaded round/pictures look great.

1.1265" and I left it at that.
Glock chamber will support OAL all the way out to 1.165" and only limited by the length of the magazine. If it fits and function checks (fed/chambered from magazine by manually releasing the slide) fine in your XD, it will work in the Glock.
My other issue is when seating the bullet they seems to be a very slight bludge in the case.
New 9mm case is tapered and narrower at the case neck. When we resize fired cases, the sizing die will reduce the case diameter down to the top 1/3 of the case. When you seat the bullet (especially the larger .356" diameter lead bullet), you'll see the bulge caused by the bullet. This is normal when using fired brass.
it varied from 1.125" to 1.130"
If you reload mixed headstamp/lot brass fired out of different pistols, you'll see variations in the resized case lengths. If you pickup range brass, you'll see more variations in case lengths and case wall thickness. Measure some resized case lengths and see how much they vary. Also, thinner walled cases may "collapse/bulge the case" ever so slightly during seating and will vary the OAL.
These variables will forever affect the OALs you will obtain when seating your bullets. 1.125" to 1.130" variation is not that bad and shouldn't affect your accuracy too much as there are variations in bullet weights (You think all of your bullets are 115 gr? Weigh some of them and you'll be surprised by how much they vary) and powder drop variations up to .1-.2 gr charge-to-charge that will affect your accuracy more.

throw anything that measures smokeless gun powder in CC's away. CC's are a unit of volume that have nothing to do with measuring smokeless gun powder. Why Lee uses 'em is a mystery.
Sunray, that is not too High Road. That's like telling someone who just got a Hornady LNL AP to upgrade to a Dillon 1050. The OP already has a Lee powder measure and is seeking information to make it more consistent. Telling him to lose the Pro Auto Disk and buy another powder measure won't solve his current problem. Also, there are many that will disagree with your statement. I will agree with checking the weights of the powder drops, as you should with any other powder measure, as they all use volumetric chamber (fixed or adjustable) to dispense powder charge.

It called for 4.5gr so I used the .49cc auto disk powder measure. It measured between 4.2gr and 4.4gr on the Cabelas scale. I did alot of weighing and comparing to try to get comfortable with the Pro Auto Disk Powder Measure.
Many people have experienced, including me, that actual dropped charges tend to weigh .1-.2 gr lighter than what the chart shows. I use the chart as a guide and use the actual weights indicated on the scale to determine/verify the charge. To get to the 4.5 gr start charge, you may need to use the larger .53 hole which may drop 4.5-4.7 gr. Change out the disk and see what the .53 drops for you. But before you do that, first make sure your Pro Auto Disk is properly lubed and broken-in.
Key point to remember about Auto Disk when changing disks or freshly filling the hopper with powder is to cycle the disk 3-4 times and dump the powder back in the hopper. This ensures that powder properly settles in the hopper/wiper chamber area for more consistent drops. I then weigh the subsequent drops until I get consistent weights.
The Pro Auto Disk has an elastomer wiper at the bottom of the hopper that contacts the top of the disk which slides back and forth. To break-in, some will use graphite powder, but you can finely shave some No. 2 pencil lead and rub the top of the disk and bottom of the wiper until they are black. Once lubed with some graphite that comes as coating on many powders, your Pro Auto Disk will slide better and drop more consistent charges. Also, make sure you are NOT tightening the thumb screws too tight, the disk should slide smoothly and not be jerky.
Small ball powders like W231/HP38/Titegroup/HS6 will meter better in the Pro Auto Disk with charge variance of less than .1 gr. Small flake powders like Universal/Bullseye/Green Dot will vary more, sometimes up to .1-.2 gr. So, using a new squeaky tight Pro Auto Disk and Universal powder varying .1-.2 gr is not that bad. As it gets better lubed and more broken in, powder drops will become more consistent.
Keep us posted on the range report!
