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.
