Early this year I bought a new .177 FX Dreamline Classic in Walnut with a 500mm STX Superior (Super Lite) barrel. I only really bought it because Joe
@viperjoe had it for such a good deal (under $1000) that I wanted to see if all the hubbub about .177 FX not shooting well was true, or old wives tales.
I had shot my newby AAFTA matches last year with a .177 Daystate Pulsar, and the gun is very accurate and shot the 10.65 H&N very well at 910 fps. I've only shot maybe 5 matches total, and my last one at the Saguaro Classic at Rio Salado in AZ my first round sucked, but my second was comparable to most of the top shooters.
Anyway, shortly after that I got the Dreamline. And stashed it in the gun cabinet and forgot about it until after EBR. Until this past Sunday. My Pulsar shot the 13.4 JSB RDMs pretty good, but shot the H&Ns better and didn't like the 10.3 JSB at all. I wanted a gun that would shoot the 13.4 RDMs for their wind bucking abilities. So I scoped up the Dreamline, tuned for 820 fps, reg. set at 85 bar, got the rough zero in my backyard at 14 yards, and went to my shooting spot.
Set a target at 50 yards. Shot a few burners, then shot this 5 shot group, 50 yards, RDMs at 820 fps. Light breeze left to right...
This was the VERY FIRST GROUP that I shot!!! SCHWING!!! That's my pinky finer...
I shot about 200 rounds, and was trying different wind holds and comparing to the Pulsar with 10.65 H&Ns. Definitely better the RDMs by a considerable amount. Some groups like this one, some not quite as good, but all would fit under a dime. Looks like I have a different FT gun for this year. It is very light, so off hand is harder, and I already suck at off hand, so perhaps I'll add a weight up front.
Oh, and the answer to the Title question -
yes, FX Superior liners CAN shoot .177 accurately...
