I've recently had this debate with myself concerning a Parker Hale Mauser action I picked up recently.
From my point of view, the advantage is improved case life and maybe another 100 fps.
The disadvantages are several; increased cost of dies, potential issues with feeding, and harder to find load data. The middle might not be as big of an issue for your push-feed Remington, but more so in my Mauser.
Good luck on the build; I look forward to hearing what you decide on!
