Riflecrank, I have a New Haven CRF .458 M70, and I'd like the ability to load the 3.6" rounds. Thanks for your post on how to do it... I found the ejector online, but I can't find the #1110 box. I did find a #1450/1460 box at Midwest Gun Works, but don't know if it will drop into my Super Express. Any suggestions?

Also, at the risk of further digressing from the current bullet topic, as a thought experiment, is there any advantage to reaming a .458 Win throat for a cartridge such as a .458 WSM/B&M that is built on a short action with a 2.8" magazine limit?
