I have Winchester model 70 in 300wsm. I not happy with factory barrel.
What chamber options do I have without any bolt mods.
The fat case head has me confused? Do I have to stay with WSM family or can venture outside the box.
Just looking for some thoughts or ideas.
Later and Thank you for any input.

Ray: I'm pretty sure the WSM's all use the magnum bolt face dimension, so you could rechambe to any WSM or Magnum caliber without any bolt face mods.
