I bought a few boxes of Winchester Low-Recoil 00 buck, but I haven't fired any yet. But...I do like the Federal Low-Recoil Flite Control wad, 9 pellet 00 buck. Its more easy to control recoil, for follow-up shots; and gives some very tight groups; that are very deadly indeed --- out to 25 yards --- and a joy to shoot.
One possible negative aspect of the Flite Control wad, is that the tail petals on the wad, will tend to partially shear off on certain muzzle brakes; with accumulation of plastic on the muzzle brake. Not sure... if it effects grouping, but my shooting partner, that had the shotgun muzzle brake, shot some very tight one hole groups at 10 yards with the Flite Control; one day at our range.
