Tuning for Reliability

I would use the paper test on the rear of the frame, should be compressed but not broken, this is you optimum cycle.

Stove pipes can happen when the toggle hits the rear of the frame and bounce forward, this increase energy in turn bounces the new round up on the ramp to hard and a jam occurs.

Cycle some dummy rounds through your gun and observe how they get picked up by the breach block and how the extractor slides over the rim of the casing. A rough extractor will cause the new round to tip up as it goes up the ramp and cause a jam

The front of the extractor can be smoothed with 600 grit or higher

Just some ideas
