JSBs 25gr Monster in .22

This is out of my airwolf at 50 yards on high power at 830fps 
I have the 1 flyer per group but otherwise it's one hole

I just launched about 120 of the newly redesigned .22 monsters 25 gr. Shot while sun was bright and low so I could watch the flight.

I tried an LW barrel AA S510, ST barrel Wildcat, and a CZ barrel KGun cricket. I was only interested in long range stability so no short range observation. All the above guns only shoot 29-31 FPE. I shot out to 98 and 118 yard steel plates. They were not stable beyond 90 yards or so out of any of the 3 barrels. The ST seemed to have the least number of fliers. My velocities were 741-753 with the 3 guns. Like shooting artillery. Have not bothered trying to calculate BC yet since I can't get them stable.

Does anyone own a .22 cal that shoots 45-50 FPE? Maybe a condor or a wolverine HP (60 FPE). Anyone with a .22 LW polygon barrel? Interested if these things will stabilize at higher speeds 880-920ish.

I have just acquired some revised .22 Monsters.
Top group is the first and only one shot at 50 yards so far. The high shot was me, not a flier.
Bottom group shot with 18.1 gr Heavies JSB. The left shot was wind blown.
Revised 25.4 gr Monsters at 753 fps/32 fpe; Heavies at 840 fps / 28 fpe.
BSA .22 Hornet.
4 in 0.25 inch ctc would have to be good for their first effort. 
Coin is USA dime.
Holdover poa was on next target up, the rifle is sighted in for the 18.1 gr JSB.
So the difference between the two groups is an indication of the drop at 50 yd between the two pellets.
Labradar doppler chronograph used. ... Regards, Harry in OZ.
