Dan,

For me, JSB Express 4.52 have given the best, and most consistent groups from my ultra-short stroked TX200 at ranges 20 to 50 meters.

They are also the pellet of choice for my other springers (HW95, HW99, FWB300_Not_S (benchrest, 25 yards)) for work >= 20 meters.

The HWs shoot H&N FTT (4.50) almost as well in the 20 to 50 meter range, but the JSB Express 4.52 is the winner (for me)

Have fun & a good weekend

Best regards

Russ
