Elements of Accuracy — Making Perfect Ammo
Q: With the micro-sized groups you shoot, you must be doing some special voodoo. What is the secret to super-accurate reloads?
The secret to accuracy is that there is no secret–a good robust process that is repeatable every time is the key.
Q: OK, then, describe your reloading process…
When I get home from the range, I tumble the brass for a couple of hours to clean the necks up. After taking the brass out of the tumbler, I clean out all residual walnut media and walnut dust. I then use a little Imperial sizing wax on a RCBS pad to lightly coat the neck area of the cases.
I use a RCBS Rock Chucker single stage press. When using this or any other press, ensure that the ram has no lateral play or side-to-side slop–that will kill your bullet run-out.
After placing the correct shell holder onto the ram I use a stiff brush to remove any dirt trapped on the surface of the shell holder. Then the Full-Length Redding resizing die goes into the press. This die is adjusted to bump the shoulder exactly .001-.002″. I have removed the expander ball on the decapping shaft. Trust me, don’t use the expander. In most cases it will just tweak the neck or throw it out of alignment.
Bumping the shoulder .001-.002″ is the key to concentricity. If your press is in good shape and you use high-grade dies your end result will be excellent. But, again, get rid of the expander ball. Your brass is fire-formed to your chamber. It is already straight and round–so you dont want to tweak it with the ball.
