unless you are happy loading 10g less powder for similar speeds and less recoil.

That brings up a good point, often people compare max loaded rounds (PSI) in a smaller calibre to a larger one with standard loads and come to the conclusion the smaller case is almost as good as the larger one.

If you go down the .284 route pretty much any long action will give you loads of room to seat projectiles way out and still fit mags. If you want a bit more velocity and something different, you may wish to consider the .284 Win based .284 Shehane, which has less taper and can take about 3 grains more powder. It's the .284 Win version of the .280 AI.

If you're chasing velocity from a .284, perhaps a 7mm Rem Mag on a Remington action may be the way to go? Mag length for a custom chambered T3 in 7RM would be a problem.
