I've never been a fan of the 284 case. I don't like the related rim and it's too long to work well in a short action with high bc bullets.
I have a 3" mag box on my 7-08 fieldcraft and it's great feeding and has enough mag box for me to run 180 eldms at 2550 fps with 1/2 moa accuracy from its 18.5" barrel. They just fit and feed well. Not too fat to get 5 rounds in and you never miss hitting the rim to pick up another round.
As much as I like it I'm still looking at the Creedmoor case thinking it could do the same thing better.
For a short action it's 7-08, for a standard long action like ruger or mauser it's 7x57, and for a rem 3.6" length long action its 280 rem for me. All with 7 twist barrels please. Although I'm currently using 280 AI when I build again I'm going to go plain 280. I had a 700 KS stainless in 280 and it was as close to perfect for me as I've had. I should have kept it and rebarreled it in a dup contour 8 twist at 22".
For 7 mags my favorite is still the 7 wsm but I'm really liking my 7 prc and have high hopes for my latest element in 28 nosler. It'll break 3000 fps with 180s from its 22" tube with moderate loads that cycle easy and are easy on brass. I've typically been one to always run things just a hair under max but brass life is good on moderate loads. I still run enough pressure for a clean consistent load.
