Shooting 13.4 out of my TM1000 RAW and shooting thru a Lab Radar unit. Had it shooting the new redesigned at 795fps. set up as a sub 20ftlb. Accuracy seemed to fall of some so turned up the hammer spring to shoot them at 810 thinking maybe alittle faster my help accuracy. I then shot some 13.4 redesigned I bought in early 2019. They averaged 824fps. over a 10 shot group. Then shot some of the 13.4 that aren't the redesigned I just bought to try out and they shot 834fps. over a 10 shot group.Then shot the new 13.4 again and they shot 810fps. The newest redesigned seem to shoot quite a bit slower so I'm assuming it's because of air loss around the skirt? I've checked all screws and cleaned the barrel trying to figure out why it's not shooting the 13.4 like it has done before.Ive got a Daystate Huntsman .22 that shoots better at 25 yards than my RAW right now, and that's not normal. That's why I tried speeding up and trying different pellets. The left pellet is the new redesigned. The middle pellet is the 2019 redesigned. The right pellet is the non-redesigned. Advice?
