Re: new brass
Hi Thomas, new brass is pretty much good to go already full length sized. I would still inspect cases myself for dings in the neck area but generally they'll be pretty good. If you found one with a ding run it through your sizing die to reshape it. No need to get to carried away with hair splitting consistency at this stage till cases are fire formed in your rig. I would also measure and confirm each case is within spec length just to be sure (good habit to start out with), then trim them all to the same length after first firing.
One reloading manual I would recommend is the Hornady one, it has an awesome well illustrated introduction to reloading at the beginning. But it is just the beginning always something to learn here mate, a great investment as far as hobbies go I reckon, enjoy.

Hi Thomas & Nathan
You can neck size if using the brass in the same rifle but after a while you may find the case grows in length which requires the case to be trimmed and FLS'ed.(Bump the shoulder back) I usually FLS every 3rd firing in my 6.5/284 and trim every reloading.
The secret to extended case life is to work up a load that gives the performance you require without running it hot, though in saying this Magnum cartridges do have a lower limit which it is advised not to load below.
Whether this will or may set up a secondary EE could be the reason, I have found out my 6.5/284 does not have to be run at 2950 fps to get the best from it though I have seen loads up to 3000+fps with 140 VLD's.
In the long run you have chosen a round that is desirable for your hunting purposes and shooting applications.
The real trick in the whole gambit of reloading and accuracy is consistency and scrupulous cleaning/inspection of your cases and components.
Lets start tomorrow with the set up for reloading your 270 if you have the gear then good stuff Nathan will chime in if I tend to go a tad off the known track.

I have a strict loading regime and was fortunate to have a tutorial session with Nathan whilst in Urani NZ my family as well. (SEPT '14)
With 50+ years shooting experience between my wife and I and 2 years for my 15 y/o son Nathan taught us allot as we are the type that even though we have habits we are open to change and what a change he brought to my son and myself.
For my son from a 3 moa to a bug hole in 4 hours of tuition with different rifles and calibre's some in the higher recoil plain, he knows his stuff.
He did say he could not teach my wife much more on her shooting technique when she started it is that good.
And the measure of the man that he understood we had the salt to be able to consistently group with his rifles eased the day for him and allowed us time to talk openly about wringing the best from a weapon.
We both agreed if you load crap ammo with little care the results were proven on the day we had 2 shooters bug holing, I tried the same rifle with rounds with a run out of 8-10 thou. And I went from a bug hole to a 1.5-2" group of 3 shots proofs in the pudding.
I will see where this thread goes and may offer my humble findings from 41 years shooting weapons I feel Nathan had a pretty easy day with my family as we proved safety was first was it at all times an getting the weapon to place the shot right on the money allowed him to relax a bit more.(None of us had ever shot any of the 4 rifled used that day)
The after noon tea was superlative but seriously bloke the front left cv on your old ute is very sad better get er sorted soon eh!!!!
Will add more to this as I think I may be of some assistance in my own way just doing basic steps and setting up the turret trimmers and uniforming etc
Anyway to one and all have a good one, so till soon time I look forward to helping.

Re: new brass
You are on the money Thomas, neck size & check length, but being Norma l think the length will be spot on, then your ready to fire form!

Best to neck size with your die so you know where you are at with your initial loads, ie same neck tension later on.

Re: new brass
Just a quick one I have discovered that NORMA brass has a rim thicker than the Lapua brass I use in this case the rims are 140 thou.
So you should adjust your NK, FLS and Seating dies for this fact.
It seems a bit harder than the Lapua brass as well I am triming mine to 2.161 for a 3.1410 COAL with BERGER 140VLD in 6.5 x 284.

One point often overlooked by some as not that important is the primer pocket and the internal of the flashole.
Standard practice for me with new brass is to uniform the pocket and then use an internal flash hole de-burrer to clean the inside hole up.
This way all the pockets are the same so the seating with the hand primer pushes it to the exactly the same depth every case you re prime because you have made them the same.
I have suffered proud primers that ruined a shot, or using the press to push them in too much pressure and ruined the anvil (misfire) I have since learnt allot of things and tricks.
Like I alluded in an earlier thread consistency is the word you can go to great lengths of time and money but if you are different the way you load your ammo and a she will be right attitude things are most likely to go to shite badly.
The other day a shooter blew his case apart at the range and the proud wood from the gas ports blew off and brass shrapnel came back peppering his face and around his eye very lucky lad was a very load bang a 6.5 x 47 I think and a gunsmith to add salt to the wound.

Simple error using a DP-3 1200 forgot to empty the powder tube changed case and load and there ya go the set up with the wrong powder in the wrong case it was that far over they bent the bolt handle on the Barnard action getting it open I doubt a Rem-700 would have made it.
Me I stay basic 1 calibre I load one powder on the bench only to suit the round, primers to suit the round, seating die, priming tool bit of music, good lighting and then in to it if I feel a real whim I may use the run-out gauge and the meplater.
Slow and steady wins the race, I am only now starting to piece the info down as my wife has not a clue what mix goes with what and what trim length does it have what primer yadayada sheesh! she does her rifle and our sons I do them as well and another 10 besides those 3 all stored in my head.
Which powders at what range, with what projie, primer/case and jump you get the picture. so I will gather my thoughts and knowing you have experience in loading will only offer what I think are reasonable ways of achieving an accurate loaded round, till then have a great day.
