Forgot... you will need a good caliper to measure cases and COAL...
.270? It makes a lot of sense to load rifle cartridges on a single stage press, reason being, bottle necked rifle cases need extra attention to load properly.
This is my method of setting up and reloading rifle cases, in a hunting rifle. (correct or incorrect? I don't know. You'll get a millon different ways to do it, but this is the most effective way I found for my self.)
.30-06, same as a .270 just with a different size bullet, assuming this is the first time I am setting up the dies for this particular rifle.
1. Tumble clean the cases, fired in this rifle's chamber, check clean cases for neck splits and case head separation.
2. Neck size and decap using the Lee collet neck die.
3. Body size (use lube) at least 3 fire formed cases with the Redding body die backed off touching the shell holder 1/2 a turn.
4. Use the Lee case length gauge for this cartridge to trim the 3 cases to the correct length.
5. Try the sized brass (empty and unprimed of course) in the bolt rifle. At this point the case should be too long to close the bolt easily and the bolt should feel like it is dragging, if not then the case has not fireformed to the maximum dimension of the chamber yet, and you will be able to shoot the case a few more times until it does become fireformed to the size of the chamber. When the cases are too long to close the bolt easily then the body die can be turned down a little at a time, the case sized, tried in the chamber. When the bolt can be closed easily with very little 'dragging', then you know the case is being sized minimally to the size of the chamber in your rifle.
set aside one of the correctly sized empty cases for later...
(this is how to get away without a headspace measuring device, for bolt guns only, as long as you are loading for one gun and not going to be changing the die setup once set)
6. If the bolt closes easily, then continue doing the sizing, decapping, trimming, and primer pocket cleaning on all the cases. I usually wipe the lube off the cases when the case is chucked in the drill for the trim and deburr of the case.
7. Recap all the cases, set on the side ready to be reloaded. Whew... by this time you'll want to take a break.
8. Take that empty case that you set aside earlier, Seat a bullet long in the empty unprimed case, close it in the rifle. Did the bullet get stuck in the lands? if so, pop it out and seat it a little deeper until it doesn't get stuck, and is seated deeper in the case by the bolt. Do this a few times, taking measurements of the overall length. Now with the bullet not getting pushed back into the case anymore by the bolt closing, you have discovered the Maximum Jam length for that particular bullet shape. For hunting rifles you don't want the bullet jammed and risk pulling the bullet and spilling the powder when unloading (this jammed state can also cause over pressure!), so seat the bullet .015-.020" deeper and start from there. Or, if this length does not fit in the magazine then seat the bullet to Mag length, and start load development from that length. You need to do this for any new bullet you want to try because different bullets have different ogives and will seat at different lengths to jam the lands. When you are done, and noted all the pertinent data then pull the bullet and shoot it as a fowler.
9. Start the charging for load development, using the method of your choosing. (Weigh every one of your rifle charges using a good scale) I'd recommend
OCW method by Dan Newberry. This uses the least amount of consumables and is very quick for finding that load that will shoot very well in any given rifle. I've used this meathod for my 6mmBR and shot it to 600 yards with great results. At this point I also apply a crimp using the Lee Factory Crimp die. This is optional, but for field use rounds I want them secure. Match rounds, I don't crimp at all..
10. Keep all your notes! (measurments, bullet types, primer types, powder type and charge, and the results from testing both good and bad) This will help you increase your efficientcy when working a load for a new bullet/powder combo in the future.
Most important parts to all this??
Maximum case length is maintained. Cases that have stretched too long will have the necks pinched in the throat of the rifle. This will not allow the bullet to be released properly when fired, and will cause overpressure.
Maximum Jam length is avoided. This may also cause over pressure or bullet being stuck in the lands when unloaded. One can shoot rifles with the bullet 'jammed', and many do, but that is a whole different story altogether. Match rounds in my 6BR are also a much different method, but this method has worked very well for my .30-06 out to 600 yards.
If I am missing something or have any comments let me know.
Straight walled pistol cases do not need as much attention as do bottle necked rifle cases, because the brass does not stretch as much when fired. Therefore, it is easier to load them in bulk on a turret or progressive. I'll talk more on this a little later.
