Quick load accounts for depth and volume.
Do me a favour, plug a primer pocket with wax from one of the cases and weigh the water volume it holds…
Just for the learning, perhaps chamber a loaded round DONT FIRE eject and look for marks on the ogive. Should they exist you have no choice other than seating deeper. Are the primers standard or magnum? I doubt your seating is too deep now. I compress loads with my 7x57 and 140 grn Barnes TSX max powder charge with zero issues.
Perhaps measure a few projectiles on the off chance they are out of spec. My other thought is your barrel, I had one that was .254 in the grooves yes pressures were high that barrel was removed. If factory loaded has no problem in this rifle my other thought is pull down a few that you loaded and re weigh the powder on the off chance there was error. Good luck sir.

Thanks for the responding... Have just tried the loading and unloading of a loaded round and there are no marks on the six tried . The primers are CCI large rifle primers not Mag. When i have loaded the Barnes tsx 85 gr you can still hear the powder when you shake the bullet so its not compressing the powder. The actual bullet weights are very good and there or there about 85 gr. What i have noticed is when i use my Lyman bullet puller the copper bullets are very reluctant to come out unlike the lead ones. To be honest i just don't know where i am going wrongJust for the learning, perhaps chamber a loaded round DONT FIRE eject and look for marks on the ogive.

is the ring above the base a sign of brass flow?
I would suggest checking your neck tension!!! What dies you using?Measure a loaded round to see what the neck diameter is then measure a sized case neck! You only want 2 thou really and 3 thou at most if it’s more then there’s the issue I would say. I had a set of Redding dies that gave me a 5 thou neck tension for some reason so I mandrel sized them after that to insure I got my 2 thou as I don’t neck turn so mandrel was the best option for me. and I don’t like them to tight I try to get 1.5-2 thou
I wouldn’t worry about this mark on the case unless you had a stiff bolt lift after the shot?there’s no primer flow on this and it’s not flattened in anyway so looking at this you have a bit to go yet until you get pressure. But as said before I woukd be using r/l 17 because that’s what the Barnes load data tells you to use so forget quick load ect follow the Barnes load data as they designed the bullet not quickload or any other manual.Following on from above i went to the range this morning and tried a reduced load 34.5 gr down from the first load of 37.4 gr .. After firing one round it was clear that the case head had a small stamp mark and the firing pin hole had just started to crater so i stopped. I am starting to think that the Vhitavouri N150 may not be the powder and may need to try something else. any Powder and weights that work would be help full before i pull out the remainder of my hair

The Barnes I use in my 3 rifles tend to seat between 80 thou and 125 thou from lands so look like this= the first is 125 thou off on the 25.06 the next is 86thou off on the .270 and the 7mm rem mag is 97thou off so I think you are way off the lands looking at the picture but I would be measuring it to check with a oal gauge before doing anything.you want to be around that top Canular I think. The .22.250(the last picture) is seated like your .243 picture but it’s a hell of a lot shorter than the .243 bullet and I have it as far in as I can to get a Jump.

That’s 1 thou tension yea?? If so there isn’t a problem there I don’t think,as I said that little mark on the case isn’t anything g to worry about providing you’ve not got stiff bolt lift or primer run out ect,the copper do thump the brass more than lead i find. Do you know what speed they were doing?
I hate to say I am baffled yet I am.

No at the moment i am just trying to get the powder weight correct and then i will loan a chronograph and give it a go.

That is an interesting statement. Why is that?
When the bullets do come loose, do they come loose with a crack?

No... No different from when i pull the lead ones.
@DS Mad buy some factory Barnes/Sako Powerhead II loaded with the same bullet and try that.
If it works, compare data, seating depth, case sizing, neck tension, case fill, muzzle velocity etc.
I have spoken to someone who could not get their rifle to shoot handloads as well as factory ammo, possibly a chamber issue as factory ammo is usually closer to the minimum case dimensions.
Never got a look at their rifle and brass so can't say more, but worth a try.

Well, it probably is not the copper bullets cold welding to the inside of the neck then.
How about this...? Is the bottom groove on the bullet on the neck shoulder junction?
