Resize new brass?

Permanently deleted user
Is it necessary or just a good idea to resize new brass? Have a Remington 141 with new brass reloads which is practically impossible to cycle. Could the brass be the problem?

    I always size new brass, it's recommended in most reloading manuals.

    +1 Briar,
    I've never even tried to reload new brass without sizing first.

    With some, limited production (read expensive) brass you can load it straight out of the box, but most people aren't buying Lapua, Nosler or BELL cases.
    With "common" mass produced cases, you should size (if only to make sure the necks are round) and check the case length (trimming as needed)

    Always resize new brass. Don't know if the brass is your problem - but always resize new brass.

    At very least run them into the die to make sure the neck is true. I've gotten new brass with undesized necks and if you try to reload without sizing first you crumple or bulge the neck.

    If this is ok you could try chambering the unloaded brass one at a time- a laborious process- to see if it is all good. Otherwise yeah, just size it first.

    I have loaded new brass without sizing it but agree with previous posters that it is not a good practice to do so. What finally convinced me that the time saved wasn't worth it was when I loaded 50 rounds of 257 Weatherby (premium brass by the way) without sizing it and nearly half the rounds wouldn't chamber in the rifle. Had to pull the bullets, size the brass and reload. Since that experience I resize all new brass. . .even though at today's prices it feels like we should get new brass produced to spec. . . .

    No kidding. You'd think that not only would it come out of the manufacturing machines already to spec, if not, the manufacturers would resize to spec.

    Depending on what exactly you are loading, I think you can probably get away *sometimes* without resizing new brass (eg with .38spls fired from a .357, where OAL isn't critical), but I think its always a good idea to do it anyway, at least for uniformity purposes.

    I don't think its a good idea to try loading ANY rifle brass without resizing it.

    I neck size all my new rifle brass, never saw the need for FL sizing new rifle brass.

    That rifle you are talking about is a pump or slide action. i always reccommend for semi-auto, lever, and slide/pump action loading to use full length small base sizing die's. If that rifle is in 35 Remington, you have to be careful to not set the shoulder back, as that is what the rifle headspaces the cartridge on. The 35 has a very small shoulder to start with.
