Too bad someone couldn't make a CRF action with a 60 degree bolt throw? Probably not possible but it is an interesting concept?
Arguably, and as per factory claims, Sako 85 is controlled round feed, 60 degree rotation, three locking lugs.
The question is, never clarified: what is controlled round feed?
There are two options to define CRF:
1. Exclusively Mauser 98 style bolt, with long extractor, that holds the cartridge during process of controlled chambering? So, nothing else but M98 bolt?
2. Any other type of bolt, that mimics Mauser 98 operation?
Operation similarities:
If we take out the bolt from m98, and stick the cartridge into the long extractor, the bolt can cold the cartridge in horizontal position.
Apparently, Sako 85 bolt can do the same.
Push feed rifle, needs to close the bolt, before extraction and ejection.
Controlled round feed rifle (m98) does not need to lock the bolt to extract and eject. Rifle can be emptied just by moving the bolt forward and backwards, without locking.
Sako 85 can do the same, without locking.
So, if the answer to above question is 2, then arguably, sako 85 is CRF with 60 degree bolt rotation.
If the answer is 1, then sako is not CRF. In that case I doubt that 60 degree rotation can be designed on m98 system.
