I shoot 200 gr cast bullets in my .40
I can reach power factor at 4.4 grns of N320.
I had to speed them up by .2 because I had 1 in 20 nearly keyhole. First thing I thought of was velocity. (Possible variation in powder thrown in progressive press)
I haven't had a problem since I went to 4.6 grns.
It does seem a bit odd factory ammo especially Geco, is not performing as they generally reach PF for given projectile weight in my experience.
I would try speeding your load up with a deeper seat depth first and if that doesn't work change powder.

Do what ya want! Ya will anyway.
Thank you for your advise.
I cleaned up the crown with a large Brass screw and some coarse,then fine grinding paste.Cleaned it up and went straight to a competition.
We were shooting feltstevne (feild competition) https://www.youtube.com/watch?v=oTsngdvfexc
Didn't get one key hole,with either 147grn or 124.I did pretty well considering,I havn't had the chance to see if its still biffing bullets around but only another go in the Randsom rest will really tell.Worst case its a new barrel for $214 USD and I can live with that.
I have loaded up a few rounds at 4.1 grains of N340,thats max,so we will see how they go.

What ranges are you shooting in that field shoot norsk?
10-50?
Do you shoot IPSC or action over there?

Yeah I would say its about 10 t0 50 meters.I enjoy "Militær felt" Military Feid Shooting.But there is Felt shooting for everything from .22's to Magnum class.What I like the most is that most of the Targets are on frames in the forest and you walk between the stands having a bit of a chat and banter along the way.
I don't shoot either of the disiplines mentioned although my mate is an enthusiastic Action Pistol shooter,he does the same with Rifles too.Action pistol is the fastest growing shooting sport in Norway.
