Both great rifles. It depends on what you want to do with it.
The bolt gun has a lot of options available to it that the semi-auto can’t have.
Theoretically, the semi-auto has quick follow-up shot advantage over the bolt.
My vote goes to the bolt for ultimate accuracy at really long range.
The following article is an example. Page 7 shows a 700 set up for this type of work:

“Theoretically, the semi-auto has a quick follow-up shot advantage over the bolt”
Seriously? It’s a lot more than theoretical! In 1967, I was assigned to cover our company sniper with my M-14 in case he ran into trouble. He had a Winchester model 70 in .30-06 and he was grateful to have me in direct support if case we ran into more than one VC. 20 rounds of 7.62mm fired as fast as possible is WAY more effective than 5 rounds fired, one per bolt manipulation. How do you think the Germans with their KAR 98K or the Japanese with their Arisakas felt going up against the M1 Garand?
