I know sir, I posted it wrong, sorry and thank you
No, it doesn't belong in the "equipment exchange"
You aren't advertising to sell or purchase either rifle, just querying the merits of one over the other. There is a difference.
All of the rifles you list are made of excellent quality materials, using top notch manufacturing processes over the time periods they were built.
They are both very accurate, if they are in excellent condition, as far as the bores are concerned, and if the stocks are solid, with unmolested bedding.
Both rifles have a lot of positives.
The Swede Mausers have become collectible since they first started coming into the country, so prices have risen accordingly.
Same goes for the Swiss K31s and its predecessors.
Your biggest issue will be finding ammunition for the K31 in the future. The 7.5x55 was mostly chambered in military rifles, but there were a few sporters made up.
Not enough to encourage any large commercial manufacturers to chamber rifles for the cartridge. Some European manufacturers will build them on special order, as will smiths here, but I've only seen two sporting rifles chambered for the cartridge, since it came to Canada.
The surplus GP11 is still available, but not every gun shop or big box store carries it. Norma makes hunting ammunition, but it's hard to find.
Your best option would be picking up several hundred cases and reloading. If you don't reload????????????
Now, the Swede Mausers are chambered in what has become a very popular cartridge in North America, the 6.5x55.
It's been quite popular in Europe since it's pre 1900 inception and almost all major European/North American commercial ammunition manufacturers make it both fmj, and soft point.
The Swede Mausers are much more prevalent than the Swiss K31s, but very similar in price, when they are in similar condition.
I like both of them very much, both for the engineering, quality, and accuracy.
They both have the same length of pull for the triggers, which is fine if you're of average height, but if you're tall, you may find the butts short, and if you're short, the LOP may be too long.
You should get your hands and eyes on both of them, bring them up onto your shoulder, in a standing offhand position, and whichever comes up easily, and the sights align quickly, should be your choice.
Try the actions as well. Some folks just don't like straight pull bolts, and others love them.
I find the balance and feel of the Swiss rifles to be a bit awkward, but that's just me.
