What I don't like are single stack magazines, hold less rounds and normally you can not top feed them. The exception being the rotary mags however my experience with these is limited to a Browning X Bolt and this carries more than a standard single feed mag.
I am in full agreement with you.
In my opinion, single stacks are modern industry shortcut, as they can be adjusted for wide range of cartridges in same production line. (cost cutting)
Shame is that some high-end guns utilize single stack mags. (for example sauer 404).
So for Tikka T3 single stack mag is acceptable because it is budget gun, but not Sauer 404.
Rotary mags, are tipical for Steyr SSG 69.
And older steyr hunting guns based on this design. I am not thrilled with them either. I have some experience with steyr ssg69, two seasons used in competitions on target, and one safari done with hunting steyr in 375 HH,of same magazine design.
Steyr rotaries - they affect two things.
Plastics, high volume target shooters in my community complain that plastic breaks. They change this with AI steel mags, there is backmarket for this. Trigger guard must be replaced with backmarket trigger guard to accept AI mags.
My 2nd expreience, I hunted during my first safari with rented older steyr, hunting rifle in 375 HH. Rotary mag, 3 round capacity
So, PH tells me, a year earlier they had to send it for service because stock cracked in position where the wood was thinned on the magazine well. The rifle served me well during first safari.
I came next year to same place to hunt, I wanted same rifle to rent.
Not possible.
Rifle was again on the service, for same issue. Stock cracked on same place, as I was told by PH.
So, it is not heavy duty stock, for this reason.
Sako 85 has good solution. Double stack mag, flush with stock, stainless steel. Can be topped from top. Very good option for all around rifle, in 30 cal.
For DG rifle, I would prefer mag with hinged floor plate, or fixed floor plate to avoid possibility of loosing the mag, in inconvenient moment. Or If i wanted to have light mountain rifle, the same, for same reason.
