Extraction Problem After FL Resizing 338/378
Am shooting a new to me 338-378 Weatherby Accumark. Once fired cases are being full length re-sized with a RCBS FL resizing die. On firing the reloaded cartridge, the bolt will barely open. I am using the same load, which fires and extracts easily using a virgin case. Am I not resizing the once fired cases enough? Any other suggestions. Regards.
