Nothing like building up a great Rifle , no matter what you choose ... Enjoy
I called Ryan and ordered an atlas tactical action with lapua bolt face. He had it to my FFL in two business days from the time I called him. You can't ask for any better than that. No worries about bullet length with a 300 Norma in that action. It accepts multiple magazine configurations including a Wyatts mbe+3. Give yourself enough freebore for the 250 a-tip and you will still have enough wiggle room with that action and be seated out long at the same time.

I think I'll go as far as the 230 A-Tip with this build. My twist won't stabilise the 250's according to Hornady 1/9

I'm awaiting completion of mine! Hoping next week it will be ready to ship.
I've been searching around but I can't find which shoots flatter between the 300 Norma or the 300 RUM? Stopping power against large game?
Also, today in 2024 are there more options available for the Norma or RUM with regards to brass etc? Which cartridge would be a more affordable option today to build upon?

I am a heavy bullet (high BC, bullet design/construction, etc, for caliber shooter, so flatter bullets are not my concern, but down-range performance at long range, i.e., 1000 yards on elk. Remember that in the .300 RUM, you must have an OAL close to 4.00" to take full advantage of the long, heavy, high BC bullets. In short, you must take action that will accommodate the longer OAL.
Which is more affordable is purely relative because it depends on the components you load. For instance, a .300 NM brass could cost you each: Lapua = $2.97, Peterson = $2.24, and Norma = $2.00. You save a tad more on bulk buying, though.

I have Lapua 300 norma brass for $220 shipped per 100 pieces. I have some Lapua 300 norma brass with over 30 firings on it and the primer pocket feels almost brand new. You won't wear it out unless you have really hot loads. The norma or norma improved is the way to go for a big 30 cal magnum that is shooting the heavy bullets. The case is shorter and fatter than the rum. If shooting 245s and having them sit optimally in the case youll need a 3.830 wyatts box at the minimum. The 4" wyatts or 3.950 Unknown munitions detachable mag system is ideal. A 300 rum or 30-338 lapua is too long to fit in any magazine if the 245 is sitting optimally in the case.

I believe the rum holds 2-3gr's more h2o then the Norma, but the Norma's shorter fatter case design hides pressure a bit better allowing for both cases to run extremely similar velocities. The Norma fits better in a mag fed gun with the heavies, and is exceptionally accurate cartridge. The negative is you need a Lapua bolt faced action which tends to be a bit more expensive.
Here's my 300 Norma pushing 230's at 3000 fps
LOL, that's why I went the .338 NMI (.338 Thor) route over .338 LMI.

NEITHER, don't need any extra anxiety or expense in my shooting world. Getting too old to worry about finding this casing or that component or the expense of something different when I do find it, all for 150fps.. I promise you the plain Jane boring ho-hum .300wm will handle anything those two can do without a lot of the baggage involved.....exactly the same bullet just slightly slower..anbextra click or two will be all it takes..
On another thread another member posted: "Get a 300 PRC then punch it out to a RUM to really take advantage of the 1/8 barrel the PRC comes with."
Will that give it any advantages over the 300 Norma?
Any reasons why the U.S. military is using the 300 Norma over the 300 win mag and 300 RUM?
