I ordered and received the pellets with the 5.53 mm head size, which I verified on the tin only. These pellets fit VERY tight in my breech. By tight I mean, they "pop" in with a good deal of pressure. They seem much larger than 5.53 mm. Almost all other pellets I have tried have 5.52 mm head sizes and fit snugly with a slight amount of pressure
I was getting very consistent and accurate groups with this pellet for the first 250 shots. During my last shooting session, I was in the process of shooting 3/4" group (10 shots) at 25 yards. My 7th pellet landed 3.5 inches to the left of the group. I figured it was me or a bad pellet. The 8th shot landed even further to the left of the 7th pellet. The last 4 shots formed a 1.75" group that was over 3 inches to the left of the main group.
I checked the the stock screws, the scope screws and everything was tight. I decided to try a different pellet (Gamo Red Fire), which has always been accurate. I shot a 1/2" group with 5 shots at the same distance.
I decided to clean the barrel, and discovered the barrel was not dirty at all. Afterwards, I shot another 10 of the H&N FTT from 25 yards. This resulted in a 3.5" group that impacted right and up from my point of aim.
I don't know how to explain this.
Here are the statistics from my Gamo Bone Collector Maxxim. Velocities and shot group is from a 10 shot string:
Velocity Min - 693 fps
Velocity Max - 723 fps
Velocity Ave - 716 fps
Standard Dev - 9.92 fps
Extreme Spread - 30 fps
Muzzle Energy - 16.66 fpe
Best Group(25 yds) - .7 inches
FYI - I have tried 16 different pellets in my .22 caliber Remington Express air rifle. This is the only pellet that doesn't fit loosely in the breech, and the only pellet that will shoot a 10 shot group smaller than 1.25" at 25 yards.
I'm eager to see what they will do @ 20m.
