Most people seem to get these in .22 these days, so finding info on the .177 can be tough, so I thought I'd put this out there for anyone interested.
Got my FX Cyclone .177 in early September, but hadn't done any shooting at the 2 lower power levels. Well, it's getting too cold to shoot outside, so I finally set up my indoor range in my shop. I can manage 10 yards in there, and it's warm, a big plus. Never did care for shooting when I can't feel my fingers :-)! Finally decided to pull the chrony out and see what this thing can do on medium and low. Since this thing has shown a marked preference for CPH's from day one, I decided to stay with those for these tests. Plus, that keeps the testing more consistent, the only variable is power level.
Started all strings from a full fill, 200 bar or 2900 psi. As stated, all shooting was indoors at 10 yards, chrony about 1 foot from the muzzle, with a halogen work light aimed down on the chrony with a shield over the diffusers. Same pellet for all strings, the 10.5 gr. Crosman Premier Heavy. String length is 30 shots. I'm not going to bore you all with long strings of numbers, just the main data.
On high power, high 969.7, low 929, avg. 953.9, ES 40.7 and SD of 8.87. 21.22 fpe avg. Shot this last Sept.
Medium power, high 843.6, low 828.5, avg. 833.7, ES 15.1 and SD of 3.39. 16.21 fpe avg. Sweet string, the graph is almost flat.
Low power, high 699.5, low 682.5, avg. 690.2, ES 17 and SD of 4.05. 11.11 fpe avg.
The accuracy of this rifle is remarkable. Granted, I was only shooting at 10 yards, and I shoot from a bench with the forearm on a really nice Caldwell rest. But it's worth noting that the low and medium power strings each went into a hole that measured .35" across. That's a 30 shot group of .17" c-t-c! The combination of weight, balance, and fantastic trigger make for a rifle that's very easy to shoot well. Expensive, yes, but this one can do it all, from match level power and accuracy to a very effective small game field gun. Hope someone finds the info interesting and useful. Later.
