Brass Prep for long range accuracy

[10ring1]

Thanks for the great video! Can't argue with that. F/l for me

Full length sizing is hard on brass and does not allow for a snug fit in the chamber. With virgin brass I am 2moa or 20 inches off at 1 thousand yards

Not if you do it properly.

I have been reloading for some time and have been shooting 1000 yard targets on my own ranch range. Not fancy by any means, but very effective. I am tired of seeing big bulls walk away at 900 yards not to be seen again.
I have been shooting every day for some time and have gotten my 1000 yards groups with my .338 LM to about.5 MOA or 5 inches.
Some of the things I have learned about brass prep I want to pass on.
1. Neck size only
2. chamfer and flash hole clean all brass
3. Use Nosler or Norma they are the same brass, or my favorite is Lapua you will not have to trim for several reloads.
4. soak in acetone or alcohol before going into the tumbler/vibrator/ultrasound wipe off
5. remove cleaned brass from cleaner and take a brass brush and clean the inside of the necks.
6. Blow each piece of brass out with an air compressor first the inside then primer pocket look inside and make sure primer pocket is clear of obstruction.
7. I use micrometers for seating bullets use ogive to lands measurements only do not use COAL is it useless especially with plastic-tipped bullets.

Shoot a lot.

Only change I would make is to buy and use bulk (5gallon) brake parts cleaner instead of acetone or alcohol. That is a very good list. What powder and bullet are you using to get that big bull? YES SHOOT A LOT!!!

I am not saying this is always true. But, it happens often.

6.5SS fire forming loads. Completely changing a case shape.



As for virgin brass loads...

Good,pics. Yes the fire formed case conforms to the chamber. It has to change shape. It,will also fit just one gun.

Carbon inside the neck is your friend.

Why?

 

[Steve Sheasly]

All brass comes annealed. Its just that some companies polish after annealing.

I will have to verify but I think you are not,correct.

 

[Ronald W Schaefer]

Man...that's a lot of work and moving parts--Ya'll shake a chicken leg over the brass before you load 'em up?

 

[jrock]

How many people clean their brass after every firing?

How many people clean their brass after every firing?

I do.

 

[DSheetz]

I have heard that a little carbon inside the neck helps prevent bullet weld were as a polished neck inside encourages it is that true

 

[Steve Sheasly]

While my reloading method is quite different then yours, nothing speaks louder than results. Five inch groups at 1,000 yds speak for themselves.
Nice work.

Steve,
Pretty much don't do most of those things either. However would like to see a good picture of that camper in your avatar.

H-1000 300 grain AB. Spindrift, Cosine of shooting angle, Coriolis effect, shooting direction and wind all play a factor. Here are some pics. A group at 1000 yards, my shooting bench is my farm truck on a spare tire, you can see the targets at 600 and 1000 yards if you blow pic up.

1. Get my once fired brass during break-in
2. Deprime and throw in wet tumbler
3. Anneal using my AMP annealer mk II with aztec
4. Full length resize using bushing style die and Sinclair Mandrel die bumping shoulder 2 thousandths
5. Trim using Giraud Trimmer to 10 thousandths off Max Case Length
6. May or may not throw in corn cob media or walnut for that extra bit of polish.
7. Prime
8. Charge cases using my Autotrickler
9. Seat bullets using Whidden bullet seater w/ bullet specific stem (buying 21st Century Hydro Press in near future.) Using Forster Co-Ax for precision loads. Dillon XL 650 for bulk loads.
10. DONE.

[338 dude]

I size without an expander. Expand with a sinclair neck expander die. I use redding and forster dies. Skim turn necks. You can get very little runout this way with a standard press, riviling hand dies even.

Exactly what I do
