I'm down to about 6 shells from a box of 25. 1 1/2oz of straight 7's. I will move to tss when these are gone and not through Nitro. But I have 100% confident out to 40 yards with these through a Pure Gold .570. I would trust them out to 45 with wither a Pure Gold or Indian Creek .555 in a couple different 1187's or a Benelli M2. These were bought probably about 10 years ago. I've never experienced any problems with them. But I do know they bump pretty hard for a 20. And I've always felt like the pressure levels on them had to be very high. The only problem I've had with Nitro has been customer service. After the last box I bought I said that would be my last. Super super long wait on shipping with no communication. Maybe things have changed over the last few years. But although I have loved the product, I will spend my hard earned $ elasewhere.
