As discussed in an earlier thread, I too had problems with Privi ammo jamming the NOSE of the bullet on the ramp. I modified a spare catridge stop to allow the cartridge to rise slightly higher. The bullet nose then contacted the ramp where the angle resulted in improved feeding. You cannot be gentle with the bolt but it does not jam. Just remove metal a little at a time and keep checking the function. I think if the cartridge is higher, it will not contact the sharp edge where you are having trouble

I have a 1952 M-S rifle that allows the rounds to feed much smoother than my 1903. I believe Steyr modified the feeding system after WW II.
