Who resizes new Brass?

I noticed that when I was seating bullets the other day the cartridges which had new Remington brass had much lower neck tension than other resized brass. I am wondering how this affects accuracy and if I should resize the new stuff. Comments?

All new brass I chamber in the intended rifle before doing anything. After that it depends on the type of brass.
For any bottleneck cartridge I just neck size. I use a Lee collet neck sizing die.
For straight wall cases that I have carbide dies for I do that since you can't really neck size those (things like .44 mag). Have found several that where out of round from shipping.
For taper cases (45-70 and hopefully a 50-70 soon) I usually just run them through the case neck expanding die. Since I run 90% cast bullets I need to do that anyway and so far haven't found any smaller than the expander.
 
Yes. I neck sized a batch of brand new Lapua .308 and had a bunch that were tight closing the bolt on. I now FL size brand new brass. I haven't had it happen but some guys have loaded up new brass only to get to the range and find it doesn't chamber because it wasn't sized correctly at the factory. Its rare but it happens, and pulling 100 rds, dumping 100 hand weighed charges, decapping 100 match primers and redoing it all over again after driving to the range just to turn around and come home? I'd rather FL size first and come home with 100 pcs once fired brass. :)

Good point, and thanks for the input.
 
Train of thought have a wreck again 'Looky..........

I always run them in about 1/2 way down the neck, just to true it up and make sure I have good neck tension. I also always slightly chamfer the inside of the case mouth as they invariably have a slight burr inside and I have crumpled the odd case neck before, seating bullets in new cases, so now I just do enough to stop this from happening. It REALLY burns me when this happens with a case from a brand new lot of 100 and now I have 99, I hate 99 or 98, I like 100. I don't mind having a few extra but I hate having lots of less than 100 or 50........just hate it !!!
 
Hear ya on the crushed case mouth. I don't own or reload for pistols, with the volume of that i could see skipping it. For me i am extremely anal in loading center fire, i just always imagine that each round is going to be for my dream animal or might ruin a group or load development.
