Things I liked:

Very accurate out of my RAW .25 cal.

Things I would have changed:

I think they are way too expensive

What others should know:

If you are looking for best accuracy you will have to weigh them. I found there to be 1.2gr.difference in weights.

Things I liked:

I found these to be consistent in size and shape, I check the pellets for bits of metal in the skirt and found very few that had material that would come out on a Q tip, With the weight being 33.94 grains that shoot hard and will deliver a kill shot out to at least 60 yds. out of both Hatsan Flash and Invader.

Things I would have changed:

Nothing
