Mine is the Beeman branded R9, bought gently used from fellow member justanothajoe a couple years ago with less than 2 tins through it. Still factory stock although I have a new in package Vortek PG2 HO kit I bought 5 years ago when I bought my HW95 .22 if or when it needs one and I've shot a 3rd tin and half of another since I got it, so ballpark 1750 shots.
Numbers from my chrony after that 3rd tin:
-H&N FTT 11.42: 753 10 shot avg, FPE 14.38, ES 9, SD 2
-H&N Baracuda 13.58: 683 10 shot average, 14.07 FPE, ES 11, SD 4
-JSB Exact 13.73: 682fps 10 shot avg, 14.18 FPE, ES 13, SD 4
-JSB Heavy 15.89: 631 10 shot average, 14.05 FPE, ES 15, SD 4
It had a Hawke Panorama on it I swapped for an Airmax 4-12x40, sighted in at 25 yards with FTT's, then just aimed dead center and shot the other 3 to see how they'd group.
View attachment 277034 All 4 shot very well and dialing in for any of them would just be a click or 2.
