Howa Mini Extractor/Headspace Issue

[ricsmall]

The Redding type ‘s’ bushing dies don’t use an expander ball. The intention is to use the bushing size that replicates your loaded round neck diameter, minus .002-.003”.

Lapua brass in Grendel anyway, is always short. I would load up a mid range load and fire it off to get a measurement of how much stretch you’re getting on the case. I’m surprised you had to even trim a virgin Lapua brass. In 10 years of shooting Grendel, I’m having trouble recalling ever having trimmed brass more than once.
