.177 Beasts shoot very well from my RAW TM 1000 at 18 to 23 fpe.
.22 off 33.9 gr Beasts shoot well to 40 yards from my BSA barrels. Beyond 50 yards they wander. At 100 yards they are hopeless. I have the feeling that they require a faster barrel twis rate than I have at approx 1:17. When I manage to get an FX crown I will try for a 1:14" or even 1:12" liner for the barrel. They are a long pellet snd as with cf rifles may require faster twist. Well we will see as it will be some ti,e before I can get a Crown into Australia. ... regards from OZ, Harry.
