Home Forums Reloading Big Game Rifles Setting your full length die to bump the shoulder.

Checking fired brass I'll see 1-2 thou variation. Same lot, fired in same chamber. After sizing still about same amount variation.

And that first piece of brass used to incrementally move the die, having been worked a few times, will usually be shorter than the next piece sized at that same setting.

Tedious, but it's about brass life not safety. When I'm trying to keep bump to a minimum will check every piece in the chamber.
