I have recently searched on-line for wad for one of my shotguns. What I noticed that was "new to me" were these "Felt Wads". I have previously only used card wads and fiber wads. These "Felt Wads" are advertised as "going directly over the powder and taking the place of the card wad and fiber wad". Really? How does one wad that is presumably somewhat soft take the place of two other wads which are essentially stiff - and sized to fit tightly in the bore? Won't the felt bend and curl if it's over-sized and forced in? The felt wads are quite a bit more expensive than card and fiber wads at about 10 cents each. But if it cuts down on stuff to carry and shove down the bore it might be convenient for a half-days hunt with not-so-many shots fired. What am I missing here?
