Holy cow! I didn’t know there was such a thing as Tannerite! (As usual, enrichment is abundant here on the UT.) I used to do machine leg presses to blow off steam, and when I was really grouchy I’d have one or two big guys stand on top of the stacks.
Perhaps you might want to consider an alternative if you need target practice but want to be quiet. You can make your own blowgun with pvc tubing that can give you hours of enjoyable target practice. Just a suggestion. (I *love* target practice!)
At the height of my weightlifting I was doing 1200 on a hip sled. 4x8. Then I’d back it off to around 800 and do toe-raisers.
Never did get my squats up over 485 though. Go figure...
That was 5-6 years ago now. Time flies.
