Neck Reaming vs. Turning…or Both?
This will be my first endeavor with the 7 mm Remington Magnum cartridge. I am going to be launching projectiles from the Savage 11/111 Long Range Hunter (AccuTrigger, AccuStock and muzzle brake with 24 total inches of rifled barrel). My goal is to maximize the accuracy potential of this system by hand crafting ammunition of the most consistent that I can produce.
My questions are:
1. What method of addressing neck thickness/projectile gripping tension/concentricity is the most beneficial?
2. Should I be looking at outside neck turning or neck reaming?
3. How does one establish the correct thickness for the neck wall? What is the optimum dimension for this cartridge?
4. I anticipate using standard Redding dies and setting them so that only the neck is resized and the shoulder is never set back after the first firing. Should I instead be looking at a neck sizing only die? This will be the only platform in my battery of this caliber and so the product will never be used in another firearm.
5. What brand brass does one recommend? I was originally drawn to the Nosler offering but read some less than flattering reviews on the Midway USA website. Many others were comparing the Nosler brass to Norma very favorably???
I have never had good success with Remington reloading components or ammunition but have thoroughly enjoyed their firearm products.
6. Winchester Western brass is currently used in all of my long arms, pistols and revolvers. Should I go for WW?
