This is using the Hornady bullet comparator not a true COAL.
What would be the best option for trying to tweak the best accuracy out of this gun? Powder? COAL? Crimp? Modify the magazine box(Not Likely)?
Well I would like to help you, but I can answer the question with the info you provided. Is the M70 a CRF or PF action? Also what would you like to shoot the 300 win at, ie. the game and at what range?
If you give me (us) this info we can help. Also you realize that just because your mag box is X length it's no matter. We can make it longer.....
