Do you resize your new brass. I just purchased 2 bags of new starline .45 colt brass

[Bugsbunnyshooter]

I have 200 pices of new starline .45 long colt brass I was wondering since its new do I really need to run it through the resizing die. I would think the brass is sized since its new unfired.

 

In the the years I have been reloading this is the first time I have purchased new brass. I have always just reloaded what I have shot.

[Bart Solo]

I don't trim for length but I do re-size.

[Jefro, SASS#69420]

Yes. First I run it through the tumbler to remove any machine oils. Then spray a litle One Shot case lube, and load as normal. Good Luck

Yes, I do re-size new brass, check for proper length and trim if needed. -- GIT

[Gunner Gatlin, SASS 10274L]

Never had to trim...but if you don't run the new brass through the sizer die you run the risk of not being able to easily chamber the rounds in your rifle....I know....been there done that

[Cliff Hanger #3720LR]

Yes!

 

New brass is like new clothes. You wash new clothes so they shrink to the final size and fit.

 

Besides. Is new 45 brass made for .454" bullets or .452" bullets?

I was not sure. I was kind of thinking they took the brass off the line before priming and loading.

And bagged it up and sold it as new brass.

[Buck D. Law, SASS #62183]

Size a few and you'll feel...that they need sizing. Run a piece you have already sized through again and feel the difference. It it takes some effort (and new brass will), it needs to be sized. Besides, what could be hurt by sizing it first?

 

I would be surprised to find a manufacturer of new ammo does not have a sizing die in the process.

[John Boy]

All my 45 Colts are loaded on a Dillon 550B - 1st station is the decapper & FL sizing die. I deprime and rotary tumble all spent cases - so they are only FL sized

[Roger Rapid]

I vote for a definite "yes." New Remington 45LC brass I have measures .4730" at the neck. When resized through RCBS die, it measures .4719"at the neck (measured with Fowler .0000" dial-micrometer) - not a huge difference, but different. (Lyman specs call for .480" -?). Interesting to note that new cases were .0006" out of round. More interesting to note that resized cases through RCBS dies are .0005" out of round (most likely due to case not springing back to perfectly round shape after resizing).

 

Important to me is not so much that they get resized, but that every round I load goes through same sizing process. ...R

[Colorado Coffinmaker]

 

Yes. You should absolutely run new brass thru the resizing die. Have you reloaded in bulk before? Just curious if you are using spray lube or are still rolling cases thru goo on a pad??

[Attica Jack #23953]

Yes, I recommend that you run it through the resizing die. I have found that some "New" brass was not cut off properly, it was not square with the case. Check for proper case length, too.

[Cheatin' Chamberlin]

I size all new brass before loading it. I don't trim pistol caliber brass, but do trim rifle caliber brass before loading it.

[Widder, SASS #59054]

YES.....and all the other above info is good.

 

I also chamfer the case mouth just a turn or two on the chamfer tool that helps eliminate any sharp edges.....especially if you have to trim any of those new pieces.

Hit the new brass with One Shot and run it thru the sizer. If you do not lube, new Starline will give you a sore arm and shoulder.

[Captain Bill Burt]

Wow, I didn't realize how little I knew about reloading. Does resizing have to do with diameter or length, or both? I've been reloading 38sp on a Square Deal B for about a year and a half (probably 15,000+ rounds) and I've never resized or lubed, or trimmed. What necessitates resizing and/or trimming? Should I start lubing? So far I just tumble and load, checking for split cases.

[J. Frank Norfleet]

45 Colt is the only new brass I have to lube before I size it. After I have shot it a couple times I no longer have to lube because there is enough powder residue on the tumbled case to go through my carbide dies.

The first set of Starline were all different lengths and had to be trimmed. The last set were all perfect trim to length, so I sized and loaded them.

If you have been using a SDB, you have been resizing. I never do anything to overall length for main match ammo. Lubing makes the press easier to run for all brass, especially new brass. One shot is in a spray can. Lay the brass on an old cookie sheet and a quick shot hitting some of the brass keeps dies slightly lubed. Certainly not mandatory but your arm will like it.

[Rooster Ron Wayne]

NO .

I have been loading now for about 15 years I have NEVER resized new brass .

I have never give it a thought

and I have NEVER had a problem from NOT resizing new brass.

I dont knock those who do .

I have never need too.

Hell for that matter I have never had to trim my brass eather .

At the light loads we shoot

you should split brass,

long before it stretches to long .

[Branchwater Jack SASS #88854]

I resize all my new brass now, if for no other reason of not wanting to pull the die out of the tool head. But even when I was loading on a single stage, I was resizing new brass.

if you are using that SDB, the cases are being resized during the 1st upward stroke when you 'deprime' them. Plus, your die in that SDB should be a carbide/tungsten die which requires no lubing.

[Captain Bill Burt]

Thanks! I was wondering if I had been skipping something that would eventually come back to bite me.

[Branchwater Jack SASS #88854]

With our SASS pistol loads, trimming is usually not necessary. I do not lube 38 cases, but have found that using a spray on lube on 45 cases helps ease arm fatigue during long reloading sessions.

[Wagon Box Willy]

Not only do I size my new Winchester 45 Colt brass, but I also anneal it. The annealing may not make any difference with smokeless but it makes a huge difference in blow back when shot in my black powder '66.

[Bugsbunnyshooter]

I just copied this from the starline site.

 

Generally speaking, Starline cases require no resizing prior to loading. Due to variances in diameter of different bullet types, it is a good practice to size the case only as far down as the bullet seating depth. When full length sizing is required, it will be noted in the box with the brass. The only Starline case that requires full sizing is the 454 Casull.

I highly agree on this by chamfering new brass. Both inside and outside. I didnt do this one time and I was making little brass rings that were fine as hair for the first couple of reloads. It was done when applying the crimp. Also was scraping lead when seating the bullet... Resize? YES!

[Brother King, SASS #69031]

All that I've shot for the last 7 years is 45LC/ACP. Not once have I ever used lube, trimmed a case, or re-sized new. My favorite is new/ primed which I seldom afford myself anymore, but I just stuck it in the powder slot, put in a bullet and keep it goin. The little brass rings? Canned air took care of it real quick.

 

I hate loading... did I say that before? Had I won the Powerball the first thing I'd do is give my loaders to the Boy Scouts. Then I'd have a 1000 new cowboy friends pickin' my brass.

 

Yesterday I shot IDPA with Peter Pi who owns Corbon Ammo and joked with him after he cleaned a stage that was giving everyone fits that he had to conserve ammo because he's backlogged over 10,000,000 rounds with 1m/ month coming in that adds.

 

Anyway, he said, "hell, give me a programmed order and I guarantee you'll never have to load again."

 

It's raining... gotta go load 1000 45ACP.

My 92 in 45 Colt wouldn't chamber unsized new brass cartridges at all!....happened at the IPBG match two years ago. The Marlin would barely feed them but I had to give it solid effort.

 

Will ALWAYS resize new brass - why take a chance?

 

GG ~

[Brasspounder]

Yup...I always full length resize new or "range pickup/purchased" fired brass the first time

I load/reload it. Eliminates any possiblity of the loaded cartridges not chambering properly.

 

After that, as long as it has been fired in my rifle, I only "neck size" and expand down as far

as the bullet base goes. That is all that is necessary and does not "overwork" the brass which

will eventually cause splitting. That will happen anyway after a while, but why accelerate it.

BTW, I have found that loading BP seems to be lots easier on the cases, with splitting a much

less often occurence. Maybe the high temps during firing anneal it to some extent?

[Dirty Dan Dawkins]

Always. Only made this mistake once.

And if I have time, trim and chamfer.

[Krazy Kajun]

Thanks! I was wondering if I had been skipping something that would eventually come back to bite me.

Adding in some gunpowder after the resizeing and priming is a good practice as well

I gess I have been lucky ..

But then I have always been lucky when it comes to killing Peo - Oh whait wrong movie.

Never give it a thought .

I probley will now

[M.T Chambers, SASS#76185]

Yes.

New brass gets sized before loaded. I don't like ammo/equipment failures, I handicap myself enough already.

Ya got to put powder in there? I thought a nice Federal Magnum primer was more than enough to get the lead to the steel. Who knew?
