Yes Tony, without going into the "pellet measuring debate" I tried F&TT, AADF 4.51 & 4.52, JSB Exact, Express and RS, Falcon Acc Plus, Superdomes, Defiant Med and Superfields.
Recently, JSB Exact Express are coming out best (grouping) at ranges from 25 to 35 yards in a few of my .177 springers.
One notable point though, the F&TT's were the tightest fit in the breech !
