A 6.5 Creedmoor would not be legal in service rifle competition.
A good place to start would be to look at the turn-key SR competition rifles sold by White Oak and Rock River. That would give you great examples of what is needed to be legal and to win.

at the club level matches, most clubs allow any service caliber, any military rifle from any country.
The OP didnt specify what sort of CMP matches they want to shoot. He did indicate that they want to shoot and they are in college, that info leads me to believe that they wont be shooting in national matches or be submitting their scores to compete at a national level.
In any case, the OP should be aware of the rule book and I thank you for providing the link.
See section 4.1.5 for alternative rifles, and it states:
4.1.5 CMP Match Rifle A rifle that complies with this rule may be used in CMP sanctioned matches when authorized by the match program. Match sponsors may divide sanctioned match competitors into two categories for a) Service and Alternative Rifles and b) Match Rifles. a)Cartridge. May be chambered for any cartridge not exceeding .308" in diameter and not less than .224" in diameter.
