I used them in a Knight KRB-7 and had good accuracy. It was awhile ago but I believe the charge was 100 gr. BH209 with a "booster" of about 10 grains of Goex 3F to prevent hangfires (because the KRB-7 breechplug was not ideal for BH209). In any case, as I recall, they printed groups under 2 inches at 100 yards. I would assume the velocity was about 1,500 fps.
