Wondering which bullets have been working good in the K31.
I know the K31 throat is short, and a lot of bullets have to be seated quite deep. I tried Sierra 168 Matchkings, Hornady 168 National Match, Sierra 155 Palma Matchking and Nosler 165 Ballistic Tips. They all had to be seated further than I would like.
I measured a GP11 round and found that at the case mouth the bullet is only .300" and doesn't reach full diameter until after the cannelure, and quickly reduces to the boat tail, making a very short bearing surface.
So I would like to know what has been working well for other people. I'm using Prvi brass.
 
I have had good luck with 174 grn Bergers.

I seat to 2.995 OAL. This fits MY rifle very well. I will try 3.000 next time, but I did do it according a great page I found over on the Swiss Rifle forums. No powder, no primer, start to seat the bullet longer than you might think is right. Chamber it, and then "smartly" eject it. Measure OAL. I did another one and measure it. Same as first one. Then I loaded them to that spec.

This dropped my groups by at least half. works great.
