[QUOTE="nvschütze, post: 1765941, member: 110896"] I had a similar problem with an MRC M1999 in 300WSM. Turns out I was sizing the cases and getting the shoulder too far down the case. The fix was to place feeler gauges between the mouth of the die and the shell-holder when it came time to resize the fired cases. What this does is to raise the shoulder more toward the mouth of the case, which moves the head more toward the face of the bolt. Once the head is close to the face of the bolt, the extractor can grab the rim and pull out the fired case. It was discovered that the WSM needed .0025" of spacing for a good grab on the rim and reliable extraction. When I designed and implemented my 300NDM mildcat, I needed .004" to get reliable extraction. If your bolt just flops down because of gravity once the firing mechanism has been removed, the shoulder is too far down the case-- which means the head is too far from the face of the bolt. I'd try spacing your resizing die .002" inches above the shell-holder. DO NOT force the bolt closed. If the bolt will not close as it should, you'll end-up galling the lugs and creating a busload of problems. I suggest you procure a Kleinendorst tool so as to feel the bolt turn into the lugs without the pressure of the firing spring corrupting what you'll feel. You'll know you have the headspace set correctly when you feel just the slightest drag when you rotate and lock-down the bolt on a resized case.
