First my method of sizing.
1 - New 300 Rum case (Remington), expand neck with a Sinclair neck expander.
2 - Run through the Redding FL S bushing die.
I start with a case "on average" with a length of 2.841. after expanding length drops to 2.827 (witch is to be expected). The shoulder stays the same through my process (A very good thing).
Now for my question: after checking 50 cases after sizing, I have cases ranging from 2.824-2.830 (Average of 2.827) . What should be the "min" trim length, to Cole out the short ones. Or should I even trim, until there fired for the first time.
Regards Mike.
