K31?

Most important, measure the case face to the ogive. Use a comparator if you have one, but they are not necessary if you're not in competition shooting with one. I use one bullet of each type and have an open ended seater that contacts the bullet at the same place each time down on the ogive. It works like a comparator.

FWIW, did you notice the difference in ogives of your bullets and the GP-11?

Hint: Clean off the sealing wax. Take your caliper/micrometer and find where the Swiss bullet comes to full .308 dia.

I don't have any GP-11, so no, I haven't been able to compare them. I was surprised though when my rifle differs so much from the Hornady reloading section for Schmidt-Rubin 7.5x55's.
I bought the dies and Norma brass to make some for my uncle's K-11. They work great in his, and don't have any issues, but in mine, some of them showed pressures. I have a chamber measuring case, to put a bullet of the type you want to use into, and gently push the bullet forward into the lands, then measure COAL and subtract a couple thousandths for clearance. Then, I can use the comparator to measure Ogive length for accurate loading.
Thanks for the info. I will also bear in mind the info on work hardening the Norma brass like you suggest.

Here are some pics of the K-31

That's PurTAY! Is that a walnut or a beech stock? They quit using Walnut in '43(?) I believe. Availability was down due to WWII. Strange thing with the serial numbers on these. They start kind of high then start over. I had two. The lower numbered one was the one I kept and it was made in '56. The higher numbered one was made in '51.

Yeah, it's a beech stock. It was built in November 1948, I believe, and issued to Alois Gissler who was born in 1929. He was in the III 187, which I am not sure what that means other than his unit. He was from the German area of Switzerland, the town of Schattdorf. This information is on a small paper/plastic tag under the butt-plate.
There is a good site on the internet, Manufacture Dates of Swiss Schmidt-Rubin Rifles which tells the serial numbers, the dates of manufacture, and the series of rifles. You may well have had one from each of two series. I really want to find a 1911 full length rifle. The way the Karbine shoots, I bet the full length one is really awesome.

Thank you. I'll have to check this out more. The more if learn about these rifles, the more I like them.
