cheers

Depends what its for.
F/TR, I only use new initially
FL resize (new for datum or every 5 firings or so)
Neck trim
Weight batch
Dont do flash holes on lapua palma
Uniform pockets after a few firings
Usually bump back and bush re size after each firing with U/S cleaning or every 5 they get a full size going over and a good polish with a touch of brasso.
Once fired/re-fired.
Usually de capped and bumped (My brass hardly moves in the Dolphin) with the bush out.
U/S cleaned
Necks polished with touch of brasso
pockets done if need be (flash holes done if once fired and purchased as such and not lapua)
Neck or full sized (depending if new to me or not/new to chamber or not).
Cleaned in brake cleaner to remove lubes/crap.
The shiny necks go through the dies beautifully.
Then go and trash all the work on the range
Jury is out re FL re-sizing pending some tests after Richness's comments, and those of Russel Simmonds recently.
Crap removal is relative, it depends what works. My feeling is that bling is nice, but not important, and sometimes can cause more aggro than good. But, buy hand polishing and inspecting the cases, you soon feel/find any nicks, dents or cracks.
Good job I only load 50 a time
I'm a maggot in another life you know
Is this an acceptable routine as only loaded 25 rounds of used ammo now!
Tumble,
Lube
Deprime and neck size
Wipe lube off with cloth
Prime
Put powder in
Load
And use.
If not what would you change, why and how.?
Where would trimming resizing and de blurring come into the equation ?
Cheers guys.
P.s I knocked up a load with the above routin and got about 20mm group at 100 yards with once fired brass as came with rifle when purchased.

Deburring is often necessary AFTER case-trimming. Many cartridges stretch on firing, and thereafter will not chamber in the same rifle or fireram. For that reason, these cartridges will need to be ful-length resized, my Swiss 7.5x55 cartridges is one such case. Many tight-chambered rifles will not take even the full-length resized cased, and therefore need to be trimmed to the correct length. This process, using an axial cutter that removed material from the neck in an even pattern, produces a ridge internally and externally that has to be removed using the suitable tool - called an inside and outside neck chamfering tool.
Remember, too, that when a case stretches, that stretch has to come from someplace, and that is the thicker material of the headstamp end of the case. Eventually, you will see a lighter-coloured ring develop there, indicative of an untoward amount of stretching having taken place - that case MUST be then be scrapped, as you are looking at incipient case head separation, something that you definitely would NOT like to experience under any circumstances.
Hope that helps.

didn't think you needed to lube for just neck sizing?

Cheers, so you only chamber debur on new or trimmed brass?
What's the difference between case trimming and full length sizing?.
Thanks
