yes i always resize new brass. i order a lot of once fired brass from MidwayUSA and MidSouth Shooters Supply. i treat them just as i would if i had just fire them in one of my firearms. the only thing i don't do is run them through my tumbler.I know this a dumb question do you guys re size new brass. I have only loaded new brass a few times and that was years ago.
reason i resize them is that even new cases, i have found with dinged necks. no way you would ever get a bullet seated. as i said, new, once fired, ammo i have fired, all mine get the same treatment.Thanks my first thought was to just load them up.Then i thought what if i loaded them up and they did not chamber then i would be taking a hundred rounds apart. Thanks for the advice.
I always resize, trim, deburr, and ream flash holes of new brass. Maybe I'm just anal about it, but it gives me the warm fuzzies.I just finished with a big batch (1000 rds) of 44-40 for a friend. The brand new Starline cases were straight walled. I needed to size to acheive the slight bottleneck.
