Almost same situation here.
Interested by using my 338 chassis in 300wm. Cheaper to shoot still a lot of fun.
Does a remington 700 300wm action will fit in a AX AiCS 338 lapua chassis?
( I guess spike223 can help me on that! )
Does a 300 wm magazine fit in that 338 chassis?
Does a 338 magazine can feed with no issues 300WM cartridges? I guess, a 300wm seems almost at home.
Any experience on that kind of build would be much appreciated!!
