I'm new to the website - so thank you for having me. I'm not new to reloading but I'm new to reloading 416 Rigby and crimping. I have reloaded several calibers over the years but I have never crimped my cartridges. My mentors in reloading were bench rest shooters and very anal about all aspects of the process and the finished cartridge.
That said, I need to know if I'm being overly critical for the big 416. After shooting new cases once, I'm finding that many of them are less than 2.8975". I would like to keep all brass between 2.898 and 2.900 ( due to my trained attention to such dimensions) I plan on crimping on the cannilure of the 400 gr. A Frame bullet.
Am I being to critical of the case length ? Can I use brass that measures 2.897 or less with the crimp and expect consistent performance?
I plan to use a separate seating die to perform the crimping operation. All dies are RCBS.
I don't expect the 416 to shoot less than MOA groups but I do want acceptable accuracy.
I would normally fire-form the new brass a second time to stretch the neck length then full length resize and trim to my target brass length. This can be a costly process in the 416.
Thanks for your feedback.
