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 after 5 shots FL size then neck size.
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. Anneal necks after 5 reloads.
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.
thankyou for sharing ,
why do you prefer to full size then neck size , I only neck (die) size my fire formed or previously fired Norma brass (6.5x47)
any help appreciated
