My hw100tk isn't fussy it will haplilly shoot superdomes as well as Jsb

But I find the AA field 8.4 grain to be the best pellet in both my Rapid and Hw100 I wouldn't want to admit the ranges on here that they have killed at, but I will say this that where I sometimes set my hide up there is a pylon wire that stretches across the field and if a woodie decides to stop off for a rest it usually ends being permenant.

But if we are talking group sizes there are very little between 4.51 and 4.52 in my hw they both will do the 5p groups at 30yrds.

Although I haven't tried the RS are they just heavier? if so that may be because they are just more stable in the air but I don't like the loopy trajectory as Bisley magnums are the only pellet both my guns don't like.
