I'm STILL bawlin'.....haven't got my hands on my "ordered" 17 Rem Fireball in SPS Varmint yet... another "new" cartridge that seems to fill no needed gap, but one I wanna try anyhow. Like some of the others mentioned and yet unmentioned, to me it's just something to play with and see how well I can get it to shoot. I really see no earthly need for it. Lots of other cartridges will fill that niche nicely...........But I still wanna try it............
