What should I build?

What do you want to do with it? The answer to that question will point you in the direction you need to go.

Long throated 30 Nosler is my take

The Nosler cartridges are Good.
Go for It.

I mean it's not a bad cartridge but it takes a back seat to the RUM

In this chassis, probably long range shooting and hunting. I had a 300 win mag in it so I don't know if the magazines are interchangeable because I was playing with other brass to see if it works in that magazine that came with that stock. I tried 28 Nosler and it wouldn't load and 338 Lapua wouldn't load also the 300 Weatherby, I do reload so it would be cool not have to buy any more dies or bullets. I was even thinking a seven 300 win not sure.

28 Nosler 8.4 twist throated for the 195 EOLs and also load for the 169 Hammer Hunter. Mine also shoots the 180 VLD to .25" 3 shot groups. Covers a lot of bases for me.

7 twist 7 RUM throated for the 177 Hammers!

It's got so many 7s in it, I just dont know how it could possibly be a bad choice?!
