Ya, go grab a tin or 2 of cphp at Walmart and have 1000 shots cheap and easy then just spend a day marathon shooting by that 1000 rounds youll see if any changes.. mine usually shoot fast new and settle in lower fps wise. I dont recall one gaining fps .. then what do i know? Lol.. or tell them you already shot 2000+ and it ain't getting improved.

Shot mine today got these results using JSB 4.5 8.44 gr . Although accurate these pellets are a little loose In the breach , I find the H&N 4.5 8.64 gr fit a lot snugger giving me higher velocity . the shot string below was with the JSB 8.44 gr

Nice. The JSB 8.44’s also fit looser in my rifle. They do deliver more energy while the FTT 8.64 4.52mm are the most accurate thus far shooting a jagged one hole group at 25 yards. With more patience I expect that to improve. My rifle is coming around with some break in. Report to follow….

And an update! Thank you all for the good information and support. With a few shooting sessions(250 rounds, maybe?) and a bit of patience things seem to be coming around. I have to assume the piston seal needed to relax. I don't really have any other explanation. Here's today's chrony time; 11.7fpe on the initial session to 15.2fpe is a nearly unbelievable change. I will need another chronograph session in a few days to fully confirm. The H&N FTT 8.64 are exceptional at this power level. At this point the HW98 is working exactly as it should be. I would not have made that bet a day or two ago. It may be a keeper!
