Suprisingly, there will be a little fine tuning when it arrives.
Tried the 'Strong Mount', it's around here somewhere...
All it did was magnify the wobble of the bench, so it's hold up in some box now.
Don't know your situation, but if you can consider insetting the press, back away from the edge of the bench about the dept of the press frame.
Keeps it from being a hip/elbow buster.
A 'Tall' table works better than the stand...
There are a TON of 'YouTube' videos on the Dillon reloaders, good watching when you are in the 'Reading Room'.
Short cases and full cases will want to slop powder.
Two things helped mine a bunch (I tried several),
One was de-tempering the index spring and switching to a 'Low Mass' index ball.
Keeps the spring/ball detent from slamming home when it indexes, and if you don't like it, Dillon will send you another spring for free.
The second that helped,
When you get yours, you will see a metal rod with pointed end facing down, that rod contacts a plastic ramp to move the case feed cradle.
EBay has a rod with roller bearing so you don't have metal on plastic wear contact (roller bearing makes it 'No Wear'),
And the bearing smooths out the cycling.
Some like it, some don't, the aftermarket stuff is cheap so you won't lose a ton of money if you don't like it...
One aftermarket thing I can recommend 100% is a knob/screw replacment for the powder bar adjustment if you are going to make weight changes, the Dillon bolt head is a pain to adjust.
You will find the Dillon charge bar powder dropper doesn't like long stick powder.
Short stick works OK...
The usual flake/ball works fine.
There are several different aftermarket kits to divert spent primers out there, some work, some don't.
If you are going to go to town, that little bin catcher gets full fast.
I have a hose on mine that drops them directly in the recycle bin under the bench.
The one I use is no longer available... But it works perfect, if interested I'll take pictures.
Extra parts never hurts, primer tubes, small parts, ect.
Get a box and keep all the 'Extras' together, and seperated from caliber change kits so you don't have 'Extra Parts' when changing calibers!
I spent a day trying to figure out where a 'Spare' part went, when I didn't need it at all...
Some days you eat bear, other days turn to bear crap!
I have three different progressives, other than tuning, I've had ZERO issues with my XL650.
I was butt hurt about the price, that went away quickly since it WORKED out of the box, doesn't wear out or break parts, and with a few aftermarket parts is super smooth & reliable, cranking out rounds at a tremendous rate, nearly as fast as you can load primers...
The frame is plenty solid, but I've seen more than one broken when people buy/use an aftermarket primer pocket swager.
I have the exact same swager, makes me cringe when I use it,
You will have to make your own mind up about using one, but it does make primer pocket rehab about 100 times faster than using a hand swager.
As I understand, Dillon will replace a broken frame exactly ONCE, even if it has the gouge from the swager.... Don't want to test that information.
Getting my dies fine tuned, powder thrower set was about all there was to it getting started, and solving little problems as they crop up is pretty easy,
I haven't run into anything everyone else hasn't, and most times there is a cheap fix on the market...
The Dillon is about 4,000 times the press the Lee 'Load Master is,
Next revamp of the bench the Load Master is up for sale or going into a box,
I have ZERO need for it, and I will never go back to the constant replacing parts & tuning it takes...
I've pulled the handle on about all the progressives, the Dillon is the best so far...
On word of warning,
When you get into deep cleaning, like taking the aluminum head off the ram,
Be aware you WILL need a timing/alignment pin from Dillon to get it timed correctly again.
Dillon sends you one for free, Dillon doesn't ship one with the press because most people will never take the press that far down.
I use mine quite a bit, so I deep cleaned it and found out the hard way about the alignment pin... Just something you may need in the future depending on how many rounds you crank out, and how much powder you sling around...
