We used to unblock the mag boxes and use the shorter ejector to make Make Mashburns and 3.6” 300 Wins. It’s so easy a Marine can do it without too much trouble or breaking much.
I done that right off the bat on my classic super grade 300 Win Mag, yes, very easy, 200gr partitions at 3.585" are perfect and shoot lights out.
It turns those silly 3.4 magazine'd 300 Win's and 7 Rem's into much more useful rifles that seem to be much easier to work with in my book.
