Thread: 7mm-08 reloads extraction issue - thoughts please

Greetings,
I am pretty sure the problem in not head space. The quoted loads are pretty stiff so the cases will be expanded to snugly fit the chamber. Very light loads can produce extraction issues if the cases are under size to start with or the chamber has excessive headspace. The pressure is not high enough to fully expand the brass. This is not the case here. Reducing the load to 42 grains for the SST projectiles may help as this will slightly reduce the case expansion.
