Size new brass?

Never having reloaded new brass before, is there any reason to run it through the sizer, 357 if it matters.

I do not load handgun rounds, so might be different? Bulk bagged new brass that I get for rifles often have some of them with dinged in mouths - so not going to accept a bullet as received by me. Also, I prefer a chamfer and to know, for sure, the length of the case to the mouth. What I buy will, I presume, be within SAAMI tolerances, but I prefer mine to be the "same" as I can make them - so same length, same chamfer, same grip on bullet. Your experience might be different. Almost all factory new brass for rifle for me is run through doing what I think is called "partial" full length sizing - and I do check most of them that they actually chamber into my rifles, before I load them.
 
I do not resize new handgun brass. Never had an issue with Lapua or Starline.

I do tumble the new brass in walnut shells so there is less chance of the brass "sticking" to the powder drop die.
 
I have never had an issue with new brass other than out-of-round case mouths.
I ususally run the case over an expander button of the correct size, chamfer, load,
and shoot. Dave.

Yes. Sometimes they are a bit banged up in the bag, so why not start with something you know is 100% other than assuming ? Imho
 
Not me. It's already sized, and this just works it unnecessarily.

If the mouth's banged up a bit it can be partially sized.
 
It wouldn't get worked if it's already the right size.

Not true and I'm surprised you didn't know that. The neck gets squeezed down on the downstroke and then expanded on the upstroke.

Do that 30 times on one of your new brass and then let us know how long it lasted.

I have no reason to do it 30 times. There are also ways around that "issue". It's definitely more important for my ammo to be perfect than to worry about slightly reducing case life. I used to not bother, then a problem arose and I switched my process.

Ok - the only reason I don't, is that I see it as unnecessarily reducing case life and it's extra work.

I take the further step to only partial F/L or Neck Size brass when I do resize it (unless it's for a semi auto or straight pull action, then it's always F/L sized), as dies are made to size brass down to an extreme that will fit all chambers, and chambers are very commonly quite a bit larger than that.

I suppose if when you tried to chamber a new cartridge without resizing as a check before loading them, and it didn't chamber, then you'd want that maximum sizing, but that has yet to happen to me - they've all dropped in easily from the manufacturer.
 
Funny you should ask. I just finished FL sizing and chamfering/deburring 20 new METALLVERKEN 8x57 JS brass for my Christmas present soon to arrive Zastava M70. I highly doubt the brass will ever be worn out, as it will be assigned to this rifle only. I have lots and lots of 8x57 ammo and brass for my other ones in the pile. I don't have any hard and fast opinions about this matter. I do it to round out the case mouth more than any other reason.
 
I have the same brass, bought from Higginson at least 10 years ago. Very thick and heavy. Should last longer than thinner brass but I'd still anneal it every five or so uses.

Same here.

With pistol brass I never bothered, the expander did whatever needed doing.

With rifle brass I resize but with the die just barely touching the shell holder

Have definitely had some tight chambered rifles where they really needed a big resizing, but like Andy said, most of the time no. The sizer die is more than enough. Perhaps quite a bit more. Depends on the rifle.
 
In reloading, everything seems to have more than one correct answer. This fortunately has only two - or does it???? :confused:

If you want a long thread, ask for the best bullet lube recipe. ;)

I have some of that stuff in .30-06 I used to load some ammo for my brother. Despite being well under max it splits and cracks in random places half the time. Higginsons didn't seem to care. An unusual lack of customer service from them in this instance.
