I only neck size, at least I think I am only neck sizing. There are die marks running nearly to the bottom. I have my die set as Speer says but I don't know ####. No issues with the brass so far.
 
If you are going to use the brass in the original rifle that it was fired from then neck sizing will give you the best accuracy. If it will be used in any other rifle it needs to be full legnth sized as they can and will jam in other guns. A friend borrowed my press to reload some .270 brass, me thinking he knew what he was doing, only resizing the necks, and he owns 2 .270's. After having to take the gun to the gunsmith to have a spent casing removed he decided full length resizing is the way to go. I only resize the necks myself but only have one gun in each caliber.
 
For my bolt guns I neck size. For my auto's I have to full length resize.
Neck sizing I'm told is easier on the brass, than full length resizing.

It depends on action type.

Semi-Automatics get full length sized brass.
Bolt-Actions get neck sized, but only after new brass has been full length sized first.

Does these mean factory new brass purchased from a store has to be FL sized first?

I just purchased some and loaded some rounds without any resizing, all the measurements are within the maximum tolerances, also the rounds chamber just fine
 
Hunting , full length a good Idea. feed the issue.
Tgt, neck ideal for that consistant burn.
Tgt/hunting maybe partial with the full length die.
Note, I would fire all cases in that chamber before the change to neck size. And chances are that cartridge will be useless to your partner who forgot his ammo home:D
 
i load for autoloaders exclusively. full length resizing for me. I'd neck size only if i had a bolt gun to get more reloads per case.
 
I neck size (Neck-size only die) for bolt-guns off the bench, and full length size for hunting. The 35 Whelen also gets a good crimp into the bullet cannelure.

Factory-new brass gets FL-sized, trimmed, chamfer/deburred, the primer flash-hole de-burred & the whole lot tumbled before the first loading.

Been at it this way since 1967 ... and so far "0" reloading problems or surprises.
 
I've done a neck size, trim, and chamfer on my new brass. What would I gain by doing a FL?
 
Most shooters prepare brass in one of three ways. They full length size, they partial size, or they neck size only.
Properly full length sized brass will have the body of the case returned to near factory dimensions. The shoulder will be in the same place as it was on the fire formed brass. Setting the shoulder back significantly shortens brass life.
Partially sized brass is sized in a full length die but pushed in short. The idea is that the body of the brass is worked less and may fit the rifle chamber better.
Neck sized brass is sized in a neck sizing die. The body of the case is untouched. The potential exists for the neck to end up eccentric to the body of the case. BR rifles where the sizing is minimal a nd the brass is perfectly concentric will do well with neck sized brass. Most others will shoot better with full length sizing.
Brass sized full length in a properly adjusted die will last nearly as long as neck sized brass providing rifle chamber dimensions are not excessively large. Regards, Bill
 
No choice here - some have to be F/L resized e,g, straight walled stuff, .30-30. .444, .45-70 and so on. Anything else I neck size only with my fired brass for my guns only. Loading for other people if I don't have the gun to check them, it's F/L only.
