Author Topic: Do you size your new brass? (Read 1190 times)

I've always used fired brass for my loading, so I'm used to sizing. My wife bought me 200pcs of nickle plated .243 brass and I was thinking of loading up some coyote rounds with it. My question is.. do you guys run new brass thru a sizer or just skip that step?
Thanks

I always size new brass. Even if its just to fix the dinged up case mouths from shipping. KN

Resize it.

Thanks for the input guys, I'll lube and size when I get home tonight.

Something else you might want to check and that is the case length.
My past experiences are that new brass from Remington is near max case length or over max and Winchester is normaly right in the middle case call out. Just something to watch out for is all.

The first thing I do is sample the batch for case length. It is recommended that case length be approximately .010" less the maximum. If needed I will then run the cases in my trimmer. I then make a pass with the deburring and chamfering tool. I next lube the case and run the case into the neck deep enough so the case neck is square. I do not need to full lenght resize the new case, unfired case. I agree with warf73 take on Remington & Winchester cases.

You'' find nickle plated brass a little tougher then standard brass. While lube is important what ever brass you are loading, failure to lube even one nickle case will cost you a die.

I have had good luck with nickle plated brass as a load management tool. When I see the nickle round I know immediately which load it is.

I never fl size new brass... I don't see a need for this except it's a lot of extra work! I do run the expander ball through the necks and back out to "true" up the necks, and i chamfer the necks so the bullets will enter straighter...

Keep in mind that the new brass isn't fireformed to your guns chamber anyway, so why resize it???

I recently bought 500 rounds of new Starline 45 Colt brass. Some were under Minimum Trim length of 1.275" by a couple of 1000ths. When I resized them, they grew a few 1000ths and then I trimmed them all to 1.275" so they would all be consistent.

For 45 Colt, definately. All other brass I shoot as is.

Starline recommends you size and trim all new brass.

DWTim · « **Reply #11 on:** December 21, 2006, 08:02:36 AM »

Resize and deburr the case mouth.

As another poster said, definitely with 45 Colt brass.

I do this because I've had batches that gave me trouble.

Brithunter · « **Reply #12 on:** December 27, 2006, 02:24:14 AM »

Yes then trim.

Ranger J · « **Reply #13 on:** December 27, 2006, 08:07:03 AM »

I sure do just in case 'Murphy' had a hand in manufacturing it.

I have always resized new brass. I don't think I'd want to take a chance of reloading 200 rounds and find out they don't chamber well. It's cheap insurance......Jim

Every brass make out there will tell you to size all new brass. I do not know of any ammo manufacturer that does not size all new brass.

Why size it? For one thing to make it all as consistant as possible, just because it comes from the same manufacturer does not mean it is all the same lot number, and even in the same lot number there will be some variance. It all depends on the guy running the machine, how much did he have to drink the night before? Is anyone at home sick? Is he late on the car payment? Did his boss piss him off?
The whole point to re-loading is to make more accurate ammo than you can buy (yeah some cost savings) so why would you not want all your brass the same?

You will NEVER get all the "new" brass the same because it came to you "undersized" in the first place... It has to fit every chamber that comes along even the ones that are normally tight, so untill it's "fireformed" it's undersized and set up for min. headspace chambers.

I mfg. ammo for many years and i can't tell you how many new brass i "didn't" resize, and in all of those years i never saw even one problem from skipping this step. If the case is visally "ok" and you run an expander ball through the neck you won't have a problem...

I also formed cases for wildcats and sold that brass too... No fl. sizeing was needed before useing them either...

If you want to take the extra step, go for it... That's all it is, an extra step.

I always size my new brass also.I check lenght and inspect each piece.........Rick

Swamp Fox · « **Reply #18 on:** December 28, 2006, 09:37:47 PM »

Drilling man speaks the truth.

I check lenght on about 10%, use the expander ball on any deformed case mouths and fireform. Set my reloading dies to bump the shoulder. Recheck brass length and trim/chamfer as needed. Then reload.

Ron T. · « **Reply #19 on:** December 30, 2006, 03:50:11 PM »

On new brass, I:

1) full-length resize it
2) trim it to minimum length
3) chamfer the inside/outside case mouth
4) "uniform" the primer pocket
5) trim off the extra brass that was forced up into the cartridge's powder chamber when the factory "punched out" the flash-hole
6) and load it.

Strength & Honor...
