Things I liked:

I like how the pellets were packed for shipping. Pellets were very clean and uniform in appearance. The skirts appear slightly thicker than other brands I have tried. Thicker skirts should reduce possible deformation issues as well as creat a more balanced weight distribution front to back in each pellet. This should aid to stabilizing the pellet during flight.

Things I would have changed:

A screw on lid would be great.

What others should know:

I am a bench rest shooter. We strive for tight groups at distance. Having recently purchased a PCP rifle i tried several different brands of pellets with little success of holding any assemblance of acceptable accuracy. That is until I tried these JSB pellets.was able to shoot one ragged hole group at 50 yards. Using these pellets I might be competative with the rimfire shooters I compete agenst.

Things I liked:

I bought these for my circa 2006 Airforce Condor. Because the MkII pellet has a smaller skirt than the standard JSB pellet, they did not shoot acceptably in my Condor. However, these are EXTREMELY accurate in a FX Wildcat III using the STX superior liner. I get all 5 shots touching at 100 yards, shooting at 920fps. I did not weight sort them either, so they must have been very consistent weight. Velocity spread was 923 to 919 fps for 30 shots.

Things I would have changed:

Twist lid container would be nice.

What others should know:

These are ideal for airgunners who do not need slugs. I can hit beer bottlecaps at 125 yards every single shot with these. My hunting range rarely exceeds 100 yards, and these are more accurate than ANY slug I have tried in the FX rifle. The skirt on the MkII variety is smaller by a few thousandths. I would try a tin of the standard variety with the larger skirt before assuming the MkII will work well in your rifle. I found the standard JSB shoots better in an Airforce, while the MKII do much better in an FX.
