How do You prep Your brass? UKV survey.

Recommended Posts

Doing my research regarding reloading I spoke with a couple  of guys I know who are all decent shooters... They all have different ways of doing stuff, especially when it comes to brass preparation. Some full length resize and anneal after every shot, some just wash the brass in an ultrasonic cleaner and call it a day...

How do You prep Your brass?

At present my process is very similar to the above, I do the following -

  • deprime
  • anneal
  • steel pins clean
  • Full length resize
  • trim
  • deburr
  • Ultrasonic clean
  • Put away in a box.
  • Write up my reloading notes.

These steps are subject to change without notice. One thing I have also started to do is label each batch of brass and try and keep it together in a 50 round box for its lifespan. I have some batches that I use for practice and others that appear to work better and are marked as competition batches.

Tumble

Anneal 

F/l size

Trim/chamfer/deburr 

Tumble again. 

Normally size/Tumble in batches of 50 but when annealing I normally do 100 (keeping them separate). 

I tumble twice. First time to clean a bit of the carbon to stop it all going in my dies. Second time to remove any remaining swarf/case lube and polish.

1. Deprime 

2. Tumble in walnut media

3. Brush necks out with nylon brush & check flasholes

4. Anneal (usually every time)

5. Full length size (FL Whidden die has a neck bushing inside it)

6. Use Sinclair Expander Mandrel on necks

7. Trim & deburr 

8. Prime

9. Charge & seat

In addition, keeping reloading notes and tying it all in with your range notes, chronograph readings and targets are all key imho.

  • Delay as long as possible
  • Moan and whine
  • Accept the inevitable as I’ve run out of ammo
  • Tumble in dry media
  • Spray lube
  • Full length resize (.223); neck size (.260, .308) and deprime
  • Clean primer pocket with hand tool
  • Trim when l can be ***ed
  • Anneal? Never
  • Prime with Lee Auto Prime
  • Charge using Lyman 1200 DPS, usually to exact weight; sometimes to +/- 0.1 grains if l can’t be ***ed
  • Seat bullet
  • Drink

Result? In my .260, for example, SDs of about 10 to 15; 1/4 MOA groups off the bench.

De-prime.

Ultra-sonic clean, then cases left to dry thoroughly in a warm place.

Full length size without the de-capping/Expander ball attached.

Trim, chamfer, debur if needed.

Use a Sinclair Expander Mandrel to resize the necks.

Clean inside of neck with patches on a nylon neck brush.

Inspect brass with an L.E.D lit, jewellers magnifying glass.

Anneal every 4 to 5 firings.

Then reload.

Wipe.

Junk/check anything I don't like the look of - don't waste time on a duff case.

De-prime

Brush inside neck and primer pocket

Body resize

Neck resize

Cordless drill - trim, debur chamfer + run up and down the case a couple of times with steel wool - cheapskate trim and clean process

100% - Simple visual check.

100% - NoGo bullet hand seating test - check neck is sized/I have not screwed up again etc etc

Sample check - concentricity gauge - QC to ensure process is giving desired results not producing junk

Store/Junk/Rework/Time to Anneal? ....

That’s a sensible regime.

Try to anneal brass every third firing.

Tumble in walnut media , re size full length,  check length.

chech cases for cracks, if found brass is scrapped.

if trimming is needed spend more time in the garage! ( find this trimming seriously boring).

clean primer pockets with Lymons prep centre.

prime using RCBS rock chucker, use Hornady lock and load scales, charge !

seat bullet check each loaded bullet, check OAL , 3”117 . Wipe cases down. Box and write load data and date of re loading.

Wet tumble with pins.

Remove primers and full length resize.

Check case length and trim if needed.

Tumble again and dry thoroughly.

Anneal every 5 bangs.

New primer.

Fill with propellant. Chant mantra. "Up one two, down one two"

Seat the bullet.

Check overall length.

.........and miss the target when fired.

Deprime.

Stainless wet tumble.

Anneal every 5th firing.

Full length resize with expander removed from die.

Use expander mandrel.

Trim/chamfer if needed.

Reprime.

Weigh power with help of Targetmaster.

Seat bullet and measure to ogive.

Shove into chamber, close bolt, pull trigger, swear.

Only asking as i anneal after resizing.

Sadness, works both ways

Shoot

Lube

Size, deprime, swage primer pockets, trim, chamfer and deburr all in one hit on a Dillon 1050

Stainless tumble

Dry

 

Or....

Shoot

Throw in bin

The theory is it gives a more uniform sizing. 

After firing the cases can work harden at different rates, once annealed all the cases are again uniform so putting them through a resizing die will in theory yield more consistent results. Of course after sizing you have also worked them a little.

How about annealing both before and after sizing then? ;)

1. Ultrasound clean (gets crud out of neck and case

2. When dry de prime

3. F/L resize

4. check length (trim to 51.0mm / 2.008”) if required

5. If trimmed, chamfer and deburr

6. Ultrasound clean (more crap out of case also cleans primer pocket and gets lube off)

7. Finish clean primer pocket with K&M cutter

 

NOTE TO SELF - must try to afford annealing machine ? This would then be done between step 2 & 3 above
