Thread: Excessive head spacing 7mm RM - can it still be used

Reloaded about 50 rounds of 7mm RM but bumped the shoulder back 0.02" instead of 0.002" from fire form size (its PPU brass originally from highlands ammo has been fired twice)
At the time I was thinking it was too much and actually dialed it back a bit to 0.015" for most of them

Measured some Highlands & Sako Manufactured ammo and that's even further back at .021" from my fireform size.


Measured a sample of 30 rounds to get the below which is the distance the shoulder has been pushed back from the fire formed size.
Average 0.36mm 0.014"
Max 0.45mm 0.017"
Min 0.23mm 0.009"

Some has been loaded as a ladder so have a range of medium to slightly hot loads.

The question is Will it cause ruptures straight away or have I just taken a few reload cycle off the brass? (cant see that i'll ever load it more than 4 times)
