** It turned out to be 180 grain Nosler and not a 135 gr.

I forgot Underwood made a 180gr and ASSumed it was that in the ammo lot I bought.

You can change this one if possible and I looked on Underwood's site... no 180gr Nosler now. I see on the sheets we haven't done this one for Chronograph? Anyone know what the part number was?

holy crap, that 800x looks like it meters terribly.  However, I'm quite surprised at pressure publications being much lower compared to other powders

800x does meter terribly, slightly better than taco chips in a progressive reloader It does work well if you're chasing speed at max loads. Best to weigh each by hand or use something like a RCBS ChargeMaster Combo.

Nice work again on the pulldown Shadow!!

When I use any powder, I set my RCBS Uniflow powder to drop dead on or slightly short.  Drop a load in the scale pan, place it on the scale and trickle with a slight tap to the powder trickler to level the beam scale.  Usually I an seating the previous bullet into the cartridge while powder is in the pan for the next round.
I see each powder charge as I pour into the casing, then it is place on the press with a bullet ready to seat.  That eliminates any double charges or spillages and it makes for Match Grade Quality for each.  I don't load for speed but have hand weighed & loaded 500 to 1000 in a secession working my magic.

Also after I have seated bullets to proper depth, I then adjust the die, usually removing a 1/8" spacer to lower the die, because the lock ring is set for crimp operation, back the seater stem out, so as not to push the bullet downward any further...

That's pretty similar to what I do when loading with powders that don't meter well, like 800x. I deprime all of my brass by hand (Harvey's Depriving tool) as I use a SS media wet cleaning system. Hand depriming provides a good opportunity to look at each case. Once dry, I lube them, run them through the sizing die, and bell the cases at the empty powder station on my 550B. I pull them at that point and set them in a bullet board. I have the ChargeMaster weighing out powder as I'm going. Each time the ChargeMaster drops the correct amount of powder in the pan it beeps and re-weighs it. Sometimes it is a little off, I usually dump 5-10 charges back in the hopper per 100. I fill all the cases in the bullet board and then put them back in the press at the powder station, rotate to the seating die, seat the bullet, rotate to crimp station, crimp.

Sounds like we both want the highest quality rounds we can make. We just go about it a little differently

Try getting a McDonald's straw, cut it, just to the length of the threads inside the dispenser tube and insert the straw in there. It helps a lot!

Also look at how to change the parameters on your dispenser. I have at most 2 per 100 on rifle cartridges, that I have to either trickle or remove .1 or .2 grains, none on pistol.

Interesting. So you're saying the smoother surface of the straw, combined with slowing down the way the Chargemaster  runs, works better with big flakes?

Yes, it helps a lot!

You can set the parameters of when it goes from full speed to medium to trickle.

The straw helps keep the flakes or extruded rifle powders from clumping together on the ridges/threads of the tube

Good tip! Thanks! I'm using a lot more Power Pistol and Longshot these days, but still have BlueDot and 800x in my inventory. I'll give this a try with those.
