You just described 30 Nosler
How about a 300 Win Mag “Modified”?

But the 300PRC allows for bullet seating much farther out of the case resulting in more room for powder. Especially the larger more ballistic friendly bullets. Below is the Win Mag (L) and the PRC (R) loaded to SAMI spec.

30 Nosler and the 300 PRC will work well. I prefer the 30 Nosler. More velocity than the 300WM and the 300 PRC . Either one has a better shaped powder column. 300 PRC is awesome too but there are more brass choices available with the 30 Nosler than the PRC at this time.

and yet its stretched to absolute max and designed from the ground up as the new hotness utilizing every aspect of design and usability sammi form and it still doesn't out perform the ole girl!!

I don't think I have ever seen someone respond to such a short statement and still completely miss the point of that statement.

Unless you are talking about same bullet weights at faster speeds, or heavier bullets at same speeds.

Don't be concerned about the 300 RUM using more powder it's more than worth it with the results that you will get , .I load all of these for it : 165gr., 180gr. and 200gr. and I can choose from a variety of powders and amounts to get great Accuracy, Velocity, Ballistics and Distance.
Whatever you decide I hope it turns out the way you want it to.
When I was looking for a 300 last year, I looked at all of them. The 30 Nosler looked to be the most efficient Cartridge out there, to me. 300 WM and 300 Wby have proven track records around the Globe. The 30 Nosler tops the WM and equals the WBY. The 300 RUM & 30-378 WBYs are marginally faster than the 30 Nosler, but have to burn 20% more powder for 5% velocity gain, have Magnum Length Actions and have passed the point of diminishing returns, again, to me. Hornady tweaked Nosler's Cartridge a bit and hung the PRC brand on it (who doesn't love a Precision Rifle Cartridge?). There's not a bit of difference really between the 30 Nosler and 300 PRC, or the 300 Wby for that matter but it's a belted round and the OP doesn't want the belt (don't blame you). Right now, given your parameters, the choice is the 30 Nosler or the 300 PRC. 30 Nosler has ADG Brass but I expect the 300 PRC will be available in that brand too if it becomes more popular. Until then you will be relegated to Hornady Brass, but I don't think that's as bad a thing as some here make it out to be. You'll be happy with either one.

The developers of the more modern magnums such as the 300 WM and 7mm Rem knwe that belts were unnecessary, but put a belt on anyway for marketing reasons thinking that buyers expected a belt on magnums because of the 300 H&H from 1925.
I have never owned a 300 WM, but shot and reloaded a 7mm Rem. in a 700 Rem. for years. The belt caused the cartridges to cant in the magazine to the point that the gun would NEVER feed without giggling the cartridges between shots. Fortunately the gun shot well enough that a followup was rarely necessary.
I switched to 300 WSM and between no belt and less tapered cases my Browning always feeds the cartridges. The 300 WSM may not be for you, but I would avoid belts. There are too many good choices that don't have belts.

The reason those have belts is because they were made from the .300 H&H, which derived from the .375 H&H prior to 1925. It was pointless to remove/rebate the belt, as it makes for an easy way to headspace the case.

You could neck down a 500 nitro to .30 caliber, no belt and you could make the neck as long as you want...

how does shooting the same weight bullets at same speeds equate into out performing it!!???
I can do face thingy too!
