Prior to my last two outings she has functioned 99.9% running Federal 7 1/2 to 8 shot. She has always run 100% with Remington Sluggers! My cheapest and most problematic ammo is Rio blue hull 7 1/2 shot. I've also been using the Tac-47 auto plug for sometime with proper ejection per a prior conversation with Tony.
The majority of the failures are stovepipes and mostly on the last (5th) round using factory mags. Last night I alternated between two of these mags with same results. I had fired about 80 rounds since the Tac-47 had been cleaned. I clean the S17 after each outing.
I followed the proper tuning to run the Rio but the failures resurfaced so I turned the screw 1/2 turn (thinking it had now bottomed out) and I started to get spent shells that were not extracted (Federal as well). I assumed this was too much gas so I put the screw back to the prior setting.
Loaded up a mag of Sluggers and she ran 100%. I will not purchase any more Rio once depleted. Any other suggestions? Thanks!
edit: after cleaning the Tac-47 I realized that there were a few more turns on the screw.
