I use a Waters Rifleman 8 shot mag in my Tikka 590 6.5x47 and it works really well. I looked into having my rifle altered years ago as I wanted a higher capacity than the standard 5 shot mag but in the end the WR mag is a good, if not cheap, compromise. WR were very helpful as well, as the mag had to be slightly fettled for it to fit my rifle. Basically I had to carefully file a little metal off one side of the aperture on the mag where the mag catch engages. Not technically difficult but a bit annoying having just paid £130 for the mag which I thought would drop straight in. All good now and it’s my go to mag.
