Rem 700 300wsm mag load

[30noslercam]

With New Zealand now in lock down I've purchased a new rifle to tinker with. A new rem 700sps 300wsm. I'm looking to do a mag fit, 1 pill do it all load. I was thinking of starting with the 175 tipped match kings or 178eldm.

Does anyone have any suggestions? Could I squeeze 190s into the mag? Looking to have the most efficient combo to 1000 yards possible

Rifle is remington 700, 24"barrel, 1:10 twist with suppressor

I was able to load the 190 Berger's in to mine but it is a model 70 I've sense moved on to other bullets.
