Well i have put a fair few pellets through the HW95 and it was feeling very strong so the next step was to check the out put.
I got a combro as recommended by you guys.
Great little tool, I checked my 77 first and it was 10.9 to 11.3 with superdomes, they are both .22 and 11.4 to 11.59 with rws hobby which i was told would be most likely to put it over. I was very pleased with that.
Then i tried the hw95 and it was 11.93 which i thought was to close to the limit for my comfort so i wipped the scope off no open sights and got it back to the shop the next morning.
The gunsmith had a quick look and said there was some grease in the transfere port so he squirted some cleaner called scrubber into the gun then fired it until al the cleaner had been expelled.
He tested it for what seemed like a lot of pellets and it settled down to 11.1 with super domes and 11.3 with hobbys.
i will keep an eye on it and hope it settles at that.
The HW95 is my go to rifle for pigeons around the barns and is shooting that good i can't put it down.
