You need to try experimenting with OAL of the ammo. I had the same issue with my RAP. It would shoot ok so I measured the jump to the lands and started there. It made a big difference. I used an inertia bullet pulled on factory ammo and used my reloading sitting die to adjust the OAL with different factory ammo and was able to hit the sweet spot with each brand of ammo. Now of course I only have tried it with Federal and Hornady factory ammo, non of the cheap Wolf ammo. Hope this helps.
