I noticed in my last trip to the range that my Razorback has been crushing some of the fired case mouths.( it hard to miss when the case hit you in the head) Normally this does not happen but with some new Double Tap practice ammo it show up more frequently. Standard factory (weak) ammo doesn't do this but the toasty DT does it with much more frequency. The cases are obviously stove piping but has not caused jams yet. What is the best way to solve this? Tune the extractor, change springs or recoil buffer? This is a stock RZ.
