just a little feedback to the OP with my Hw100.

After trying about 20 different pellets I am semi settled that at least some of it is the pellet. I can pretty much do one hole at 20-25 yards. But down on our 50 yard range we are talking 1-1.5inch center to center on the grouping which is "ok" but I wouldnt have said it was fantastic. This is obviously random flier and wind pending. But it seems to like really light pellets, JSB Diablo RS lights - 13.x grain seem to be order of the day from the testing pack. H&N FTTs / pretty much everything else gives a spread of 2+ inches at 50 yeards which is not what I was expecting from a Hw100.

How much I am over expecting after getting 5p groups at 50 yards with my .177's I don't know but we shall see when the tin arrives this week.
