Re: Tikka rebarrel to a 6br??? Magazine???
If you want to mag feed this cartridge, there are easy and difficult options.
If you choose the sako, it has a magazine that feeds from either side, and that makes feeding difficult and not 100% reliable.
If you pick the howa, it can be converted to take a floorplate that accepts an aics magazine. These feed centrally, and are double stacked. You can use any length bullets you need, and it feeds 100% reliably.
You also need a sako extractor to make the gun eject cleanly.
I built a 6mmbr repeater on a surgeon action, it has a 10 round aics mag system, and i fitted the sako extractor, because the remmy one would not throw them clear. Its in the wrong position on the bolt face. Mine is 100% reliable, no matter how fast or slow its cycled, and i use a 90 grain scenar in it.
