Calcium is one of the most critical things required in a pullet's diet because it is necessary to make hard egg shells. Feeding hens an all-mash diet is generally suitable because all-mash diets normally contain around 3% or more calcium.
The .327 Federal Magnum is a cartridge introduced by Sturm, Ruger and Federal Cartridge, intended to provide the power of a .357 Magnum in six shot, compact revolvers, whose cylinders would otherwise only hold 5 rounds.f you want more than the .327 delivers, you have to go to the .357 Magnum, and having done so you will pay mightily for it. An SP101 in .357 delivers a 125-grain JHP at more than 1,300 fps, but you get only five shots and muzzle blast and recoil that could make a brass monkey flinch.
In mid-2010, Ruger officially announced the LCR 357. The revolver is a small, compact revolver that shares many of the same design characteristics of the original LCR, but chambered for the more powerful .357 Magnum. The LCR 357 is slightly heavier than the original LCR revolver, but otherwise is very similar.
