I have cut open 2 of the following from different boxes of ammo, with the following results...
Rem Nitro Steel 3"- Round uniform shot well sealed crimp
Rem Sportsman HV 3"- Same shot as above, less water sealed crimp
Kent Fasteel 3"- Polished shot uniform and round, no water sealant
Win Xpert 3"- Mixed shot sizes(from 6-2 in a 3 shot round) barely
any round shot, no water sealant
Win Super X 3"- Identical to Nitro Steel with better water sealant
Federal Game Shock Steel 3"- Round pellets with pits and burrs on some
shot no water sealant
Fiocchi Speed Steel 3"- Round uniform shot few pits or burrs on some
shot
Just my opinion but your best bang for the buck is Speed Steel by Fiocchi or Sportsmans steel by Remington... both rounds shoot kinda dirty compared to more expensive ones but I'm okay with it for the few bucks I save... hope this helps, To be honest, after opening an Xpert I will NEVER buy them again unless its my only option...
