Here is how I make things feed; look at it when it is doing what you don't want it to do. Look through the situation and you can see what will need to be done to change it's behavior. A slow motion camera can work. Then, make the change required to the steel. It is either intuitive, or impossible, for some to envision. One possibility is that the maker made the feed rails too wide, but that is a complete guess.
Bobster, the bolt starts to pick up the round and the round moves a little and then bolt slides over the top of the case. If you stop the bolt and pull it back then restart the bolt forward again it will feed.

Apparently, it is a bullet nose issue. Take some Dykem or a blue Sharpie and color the feed rail on the left side and any ramp in front of it. Cycle and look for the contact point(s). Stone that area until you get it to feed.

So far I've been just dealing with it. It has gotten a little bit better as the rifle was shot very little. I have been double clutching it a bit like you. The front of my feed rails have been worked on but perhaps not enough.

The feed rail is preventing the bullet end from moving upward and toward the center at the onset. That is most likely because the current chambering is longer and wider at the bullet end than the action was initially made for. So you need to remove a bit of the mid/forward rail to allow the case to lift forward as opposed to dropping in the back when forced forward by the bolt. The cartridge needs to slide upward easily enough that the case head doesnt drop. That force may change a bit with the magazine load, so make sure it works with only one case in the magazine. I do this lightly and carefully with a dremel then smooth it out with sand paper. Just grind a nice gentle taper that increases toward the front, but dont touch the back half of the rail at all.
