Zastava 300 WM

[swashington]

Hey all, I found a Zastava 300 WM in left hand. I am considering getting it and converting it to a 458 WM. Does anyone have any first hand knowledge of this rifle and know if I would need to put a new stock on it to handle the increased recoil of the 458. As I understand it after a new barrel there are no other changes needed to change the caliber. Am I correct in this?

Input much appreciated.

May need feed lip work, most likely will, I’ve got a barrel off one that was converted to 338 and that still needed some love to get it to work

I know very little about this brand of rifle. Can I assume that it is a reliable copy of the Mauser?

I assume you mean the zastava m70 sporting rifle, which is a fairly good copy, some had issues with scope holes drilled off centre. Which could be corrected by appropriate rings and bases, they are well made in general out of good steel.
