Pellet Drop
My HW98, 5 shots spot on then suddenly the next 5 drop about 4 mildots, then they come back up again. I change the breach seal still does the same. I thought it's probably the PTFE sleeve that I put in it, maybe its catching). I strip the rifle down only to find I hadn't put one in it. I look at the piston seal to seal its got a slightly rough patch on the edge but I have used worse. I check that the TbT guides are not over tight, they are fine. I re grease the rifle put it back together (thinking I should have changed the piston seal).
At the range the first 7 shots spot on, Yeeeeeah I thought then they dropped about 4 mildots again.
It goes through the chrony 11.75 ish for the next few shots then drops to 11.3 oh dear me I think to my self. I have changed the scope just to confirm it's not that. Have tried different pellets and it's just the same and cleaned the barrel. I tried tightening the axis bolt and now it's up and down like a whores drawers. I am perplexed I have a couple of things to try.
My thinking is now that leaves 2 things, the piston seal or the spring.
You may ask, did it do this before I put the TbT kit in, I can't be sure as I had only used it at 20 yards heard it boing and changed it quickly.
Over to you Guys for advice please, thanks in advance, Ade
Shooting Air Rifles is like being a pubic hair on a toilet seat.
Eventually someone comes a long and P's you off.
They usually have a PCP
