I did a mini jug test on the low noise CBee 33 gr HP. Amazingly the one round that I recovered expanded perfectly! I shot 3 rounds from my Winchester 9422 with a 20" barrel from 10 feet. 2 rounds exited the 3rd jug and I didn't find them. Possibly because they didn't expand. One of them dented the 4th jug but didn't penetrate. The recovered round was in the 2nd jug and it was a beauty.
I had my wife stand back about 25 feet for the "sound" check and she said it was like a pellet gun .... I think it is more like a weak firecracker. Remington says 740 fps - 40 lb-ft at muzzle, 687 fps - 35 lb-ft at 50 yards. -2.7" drop at 50 yds with 25 yd sight in. They don't mention the test barrel length.
I shot some at a target from only 10 - 12 yards today and I was right on target. The scope was previously sighted in at 25 yds with Aguilla 40 gr round nose.
Overall I'm pretty pleased.
