10mm Delta Elite Medium Power Loads?

[Barry in IN]

Perhaps this a good time for a reminder, or for any new reloaders a tip:
Always keep an eye on the powder level when reloading. 

You know what X grains looks like in a case because you have your first case as an example.  It was loaded after adjusting the powder measure and checking it on the scale. From there, it went straight back into the case.
That is your standard for comparison.

If using a single stage press, comparing is easy.  You hold a light above your case loading tray, angling it so you can see the level in each case.  As you go down each row, you are just eyeballing for a consistent level.  This won't tell you if each charge is absolutely dead on the money, but if a charge is very much low or high it will be apparent.   A double charge is so obvious it can't be missed.   

On a progressive, it isn't much more difficult.  Many types of flexible stem "snake lights" can be mounted to the press and set so the beam shines into the case mouth after it receives the powder charge.  Again, you've set the first case's charge by the scale and know what it should look like. As you go along, they should be monotonously consistent in powder height.   If not, you will catch it.
But you have to be watching for it.   It might add another quarter second to each run of the handle (which I know will feel like a lot when you do it) but it's worth doing.

For $50 ($40 after rebate) an RCBS Lock-Out die is something I won't work without.
