I had good results with some RWS Pointed pellets through my FWB Sport 147. However, as I only shoot this .22 to farmyard ranges then pure accuracy is a moot point as its no real test.

.177, even a wadcutter is pointy enough.
In 12ft/lbs rifles then a point isn't going to make any real difference to penetration anyhow. Above 12 ft/lbs even less.
To have the point in manufacturing and tin storage there is loads that could effect the final accuracy.

Just shoot the pellet that gives the consistent accuracy. Pellet placement is what counts.
