300WSM Berger 215 Hybrid Question

[blackfoot]

Wondering if a 300WSM with an extended magazine box (Wyatt) can be chambered and throated to work with the Berger 215 Hybrids. By work I mean feed and be able to run at decent velocities (2800+).

I run a 210 berger in my 308 win at 2374 fps and 300 rum runs 215 berger hybrids around
3100 fps.

308 win with 40 gr of powder
300 rum with 89 gr of powder

I would say you would fall somewhere around 2800+. I'm seating bullets to mag length, nothing long.
