Brass Prep for long range accuracy

Steve Sheasly said:
Your first sentence is obviously true. Second does not make sense to me. Fire formed brass ---brass fire formed,to a,specific chamber ---- in my experience is always more accurate. A bit stiff to eject sometimes after 7 or so firings but in my experience much more accurate. The projectile is aligned with the center of the bore. Not sitting a few thou low so when it engages the lands it comes out more concentric more stable increasing accuracy. I hope I explained that adequately.[/QU
Very good explanation I completely agree

And this comes from a lifelong neck sizer ;)

ok he finally said it -- the reason bench rest shooters do not neck size is that on a hot day a round may not chamber or worse yet it won't eject and that might cost them a match. If I were in a competition I would also full-length size. These guys spend thousands of dollars a year and have custom made dies (I am sure) to get .002 uniform full size. I know that when I neck size my groups got smaller. I suppose if I wanted to spend the cash I could get custom dies but I am a hunter, not a bench rest shooter. I have never had a round stick or refuse to chamber because when I hunt it is always cold. Great video but more detail would have been helpful.. Thanks for posting that.
 
As far as brass goes norma brass took me several firings an several trimmings to get same impact as my rem brass. Gun sighted in dead on and norma brass all shot to right of x by 2 inches at 100 yrds. I honestly beleive the necks where not square until a few trimmings

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.

Hello Steve. Hope I can help. If you are getting 5" groups at 1000 yards, it's not a reloading issue. It would be inexperience field shooting. Please don't take that wrong. I just didn't know how to say it. This will be a little lengthy. 1st. Get your zero @ 100/200 yards whichever you prefer. (I use 100). 2nd validate your rifle facing true North. Meaning get all your drop data out to 1000 yards facing true North. That is very very IMPORTANT!!! Coriolis does not effect your drop date shooting North or South. Please pay close attention. If you are North of the equator remember that when you shoot East your bullet impact will be high. If you shoot West your impact will be low. You must train yourself how to dope wind. You are no longer shooting at a bench anymore where everything is almost perfect. When you are shooting over a canyon or water open field thangs change very quickly do to wind and humidity. Man this will take a long time to explain all this. I would to sit down with you for a few days, but keep in touch with me and I'll help you along the way the best I can. Get your zero and drop data out to 1000 yards first then get back with me.

I do all that. .5 moa at 1000 yards is good enough for me. Can you do better?

The reason an unfired round sticks in the chamber often times is because they are jamming bullets into the lands and if unloaded ends up dumping powder in the action and they are done for the day. This is why competition shooters preach full sizing

That's funny. Where I live it,always blows. I measure the angle cub cosine .2 inches left for cor. Effect 6 inches for spin drift 1 to 5 moa for wind. I have the targets due North. I am inexperienced. Started hunting at 7 years old I am now 62 and have been reloading of years. But still learn everything I can. No one knows it all but all know a lot. So I listen more than I talk.
