My rifle is a custom Sako L61R. Rifle was originally in 7 mm Rem Mag and nothing has been changed in the action. This rifle feeds all ammo with no problems at all. In my opinion it is way easier to make old Sako to feed properly than to hand tune a Mauser which needs everything to be changed. That's why I like to use Sako AIII, AV and L61R in my projects. At the moment I have .300 H&H, .375 H&H and .400 H&H built in these. I also have one barreled to my own 9,3x68 M&W.

All of these rifles use the original magazine boxes and unaltered actions and they work like nothing else. I also have a bunch of Mausers and I have to admit that I'm not that big fan of CRF anymore.
