[QUOTE="Pdvdh, post: 1476743, member: 4191"] I don't see much difference in case head strength between the Norma and RWS 8x68S brass I recently tested. I measured and monitored case rim expansion during load development while working up to, and past, maximum pressure loads. Was measuring MV while firing the identical bullets in both brands of cases. So I knew I had equivalent chamber pressures based on equivalent MVs. Case rims begin to expand at very similar MVs. The RWS is very slightly stronger at the case head and primer pocket, based on my testing. I expected the RWS to be clearly tougher. But had to conclude it was only slightly stronger. [/QUOTE]
