I'm not talking about jump to lands strictly speaking, though it's probably related to some degree.
While I have no doubt that works, the advantage to using the Redding body die is that it doesn’t work the neck, it’s only sized by the collet die. This will yield much better brass life IMO. The regular sizing die does size the neck down and your just sizing it back up with the mandrel so basically your just replacing the expander ball with the mandrel while unnecessarily working the neck. How much difference this makes, who knows, perhaps not enough to be much of a factor, especially since in your case you anneal after every firing.Jet, I just removed the expander ball completely from my lee FLS die, I then use the lee collet die to size the neck since its using a mandrel it wont pull the neck off axis. It made it almost perfectly concentric. I anneal after every firing so not worried so much about case life but man it was eye opening how bad the expander ball can be.
What is the biggest group's size?My goto 300WM bullet for long range work is the 208 Amax. Unfortunately, NLA. I bought 1500 many years ago and have about 800 left. 76gr of H1000, .020" jump , 2760 fps. my best group was . 68" at 200 yds. Very consistent load. R700 Sondero rifle.
Bart B,I wore out several Garand barrels shooting on the USN rifle team. Each one lasted about 3500 rounds.
New cases always shot most accurate. None of the military teams reloaded their fired cases. Fired case heads were not square and the barrel whipped different before bullet exit depending on the case orientation in the chamber.
