Re: If you pull bullets do you resize your brass?
I have pulled bullets, and reloaded the brass w/o resizing. I did not have any problems. Just make sure you don't deform the brass when pulling the bullets

No. I do mark them to use as sighters or 200 yard off hand though.

I'm with this guy. I don't expect to get the same accuracy, but depending on how many I've got loaded...I just send em as sighters or sling em off hand at a grand.
I was doing some load development 2 weeks ago and had some cross wired info that led me to end up with three charges with three rounds each that were too much juice. 9 bullets that I didn't want to waste since I was still doing load development.
Pulled the bullets, resized the brass and re-juiced em. It was new brass so the primer pockets were still tight, so I did re-use the primers.
Got some 1/2 MOA results that I may or may not have gotten if I didn't resize. I feel it just makes sense to get the neck tension back to what it was before.

It depends on what you plan to do with the ammunition you are making. If you are testing loads then absolutely resize.

Re: If you pull bullets do you resize your brass?
I just pulled 140 cartridges without resizing and shot the new rounds at 1K. For the most part I was very pleased with the results although I had one or two crazy fliers and attribute it either to the case or a bullet that got nicked during the pulling process (reused all the bullets). Of course maybe I'm just blaming my crazy flier on something besides myself.

Re: If you pull bullets do you resize your brass?
I just had to double check powder charges on some test loads. Had 6 groups of 8 rounds with different powder chargers (Garand).
I pulled one of each group to note the powder charge, and reseated. There was no difference across the chrono as the others (well within the ES).
I have also pulled some bolt gun loads, and nothing to note across a chrono.

Re: If you pull bullets do you resize your brass?
I generally run em through the neck sizer just to be sure. I've gotten away with not doing them, when on the range, but in the shop, I resize the neck.

Re: If you pull bullets do you resize your brass?
If I pull bullets (I use a collet), I have found looseness with neck tension if I just reinsert the bullet. Comparing bullet diameters at the neck junction, sometiomes they are smaller than unseated bullets, I think this is a product of the way I use the collet (I'm still learning).
Factory loads seem to have neck tensions that are very stiff and the collet needs to be tight enough that some of the bullets get their diameters reduced. It's enough to make one seriously consider swearing off pulling factory loads apart with the collet.
I have tried resizing the cases with the decapping pin removed, and sometimes this works, and sometimes it doesn't. Occasionally, I need to set (some of) the pulled bullets aside and use unplulled ones if I want a decently consistent neck tension with the reassmbled cartridges.
This comes mostly from a recent project where I pulled bullets from factory Boxer (PMC) 7.62x39, and reloaded the same components with weighed charges, to try and get a handle on the best potential the factory components and basic load data can deliver. Think of it as Lowtech Mexican Match.
I'm in the process of load develpment for a Savage 7.62x39 Scout, and I consider any info to be useful. Considering how the rifle performs with unmassaged factory ammo (between 1MOA and 2MOA at 100yd), it may just be made well enough to get some respectable accuracy with handloads (good enough that I just replaced the 2.5-10x42 scope with a 6-24x42 scope).
In any case this and all projects are on hold until Spring, it's going below freezing in my garage these nights, where the reloading setup lives.

Re: If you pull bullets do you resize your brass?
I always at least resize the neck, have tried it without and have had problems with shifting seating depth when feeding from a magazine.

Re: If you pull bullets do you resize your brass?
If your press is indexed to pull the projo straight out or if you use a kinetic your brass should not be deformed. The old Mex Match M118 shot great but that was using new bullets. Your question was about the need to resize the case.I would not likely reuse collet pulled projos for serious accuracy purposes.

In case anyone wants data (sort of) on this. I've pulled bullets and reloaded the brass without re-sizing and they showed about a 10-15fpf lower velocity. I threw the loads into a bullet jump test I was doing just to see what they'd do. Everything else was the same. I seated the bullets with jumps between two of the other groups just to keep them separated. Needless to say, I ignored the data (this was for a Ruger Precision Rifle and 30 thousandths seemed to work best with just about every bullet I tried). And no, I'm not very proud of the velocity spread I had going here...
The necks on the pulled brass just won't have the same tension anymore when you go to re-seat bullets unless you resize them first.

Just say you sized your necks to where you wanted them to be, would you run an oversized mandrel through them now just for good measure? That is more or less what you do when you seat a bullet, when you pull a bullet, brass does not reset itself to where it was beforehand.
Only you can decide if it is worthwhile to re-tension.
