Hornady has data for this specific bullet, although their COL will be far too long. You'll need to determine the correct COL for your rifle, as the K-31 has a very short leade. Doing this, you'll need to work up to any published data carefully, as your COL will be shorter than the published. For some reason most of the data out there was developed in the G-11 series which have a much longer leade. I would use generic 168 grain data, start low and work up after determining your COL specific to your rifle.
I've never loaded that specific bullet. I have loaded Hornady and Nosler 168 HPBT. I prefer the Nosler 155HPBT. It works better with the K-31s short leade and recoil is milder. I had to seat 168s rather deeply. I'm usually shooting 200 yard CMP or 300m international, and the 155 is plenty of bullet for these ranges. Per my notes, 2.905" was my COL with the Hornady 168BTHP over 42.4 gr IMR4320. This should give you a starting point.

I think that is good advice, at least that is the approach that I take. I have 2 K31's and the throats are quite different so would recommend measuring the COL to the lands so you know. I found IMR4350 to shoot as well as any of the powders that I tried with 168's, but I didn't try them all.

As always, use internet data with caution, but this site has literally hundreds of loads posted and I found the forum to be legit in every way. A treasure trove of data.
That is the only data page in the very thin book. The first few pages are reloading safety.
There is a Swiss Rifle Club in CA with their own range. Look for their website. If anyone has the answer, they would

I'm VP of the one in MN. We beat up on the Cali one in shared matches LOL. The problem with SRCs is they shoot primarily GP-11 ammunition. We get it directly from the Swiss military as it is required for use in sanctioned Swiss matches. You'll find much more information on the Swiss Rifle message boards, as these are populated by many more reloaders.
I've found IMR 4064 to be good for all things medium sized, including the K-31. I'm pushing 42.5 gr with my 155 HPBTs. 33.7-43.2 gr is the range listed in Hornady 5th for 168s. IMR 3031, H 4895, I4320, I4350, AA4350, and VN160 are also listed in this edition for 168s.

Lol. I didn't know there were other Swiss Rifle Clubs in the US. Also, I don't load for Swiss rifles anymore after my three rifles burned up in a fire. I'm still saving the metal to turn in for a Liberal Gun buyback. When preparing to reload for my rifles, I was planning on R17. Isn't that a good powder as well along with Berger bullets? Also, do the Swiss shoot boxer primed cases? Maybe you can arrange a trade with them for it or even the Berdan primed brass if you can acquire Berdan primers. There use to be a vendor that sold berdan primers years ago.

R17 should be a good powder. I believe the bulk RUAG version IS milspec for GP-11. I haven't seen much data for it or any of the Alliant series though. GP-11 brass is very good, berdan primed, and of a different sized primer than "standard" berdan primed brass. It is reloaded in Switzerland but the primers are not exported. We have a new shipment of recent production, and I haven't checked that brass to see if they've switched to a standard berdan primer.
I'm not a fan of Berger bullets in general for military rifles. They seem to be very difficult to find good loads for. In my limited experience with 6.5x55 and Berger 140s, they didn't group very well. They are also very expensive compared to other options.

Howdy do you use the hornady bullet compensator to get c.o.l or using tip of bullet

I use a bullet with some tape goo on it, seated in an un-resized casing fired in the same rifle. I wrap a bullet in duct tape, give it a light pass with a torch to leave some adhesive behind so it loosely sticks in the case neck. I then gently seat that cartridge in the chamber and mark the COL. It may take a few tries to get the knack and extract the cartridge as a whole without leaving the bullet behind. This gives me a ballpark zero freebore COL. I then verify with a sized and ready to load cartridge and powder, seating a little long of this number and black the bullet with sharpie. You'll feel the rifling start to engage before full lockup and see the marks on the bullet. Back off a couple thousandths at a time until you find actual zero freebore. I like to load 2 thousandths short of zero in the K-31
