20 Rounds of .327 Federal Mag Ammo by Speer - 115gr JHP

The original concept of the .327 Federal Magnum is so interesting that if you don’t know it, you should. Ruger wanted sub compact guns to be able to fit six rounds in their cylinder but couldn’t make it work with the tried and true .357 Magnum rounds due to their large case diameter, while still maintain the type of profile that made the most sense for the concealed carry advocate. They decided to help develop a cartridge that mimics the performance of the .357 (or got really close) but which shot a .312” projectile or what is commonly referred to as a .32. Because of the innovative cartridge metallurgy, case design and the powder choice, the cartridge casing could handle double the pressure of the closest predecessor for that diameter of projectile. Hence, a modern-day Magnum killer was born. The .327 Magnum is essentially the Super Magnum version of the .32 H&R Magnum, which was already somewhat substantial in performance albeit a bit less popular.

The round can produce spectacular performance and instead of 5 rounds in a concealed carry gun, the firearms makers can now fit 6 and keep it legitimately slim. This round achieves 1335 feet per second velocity and 455 pound feet of energy delivery. The casings are reloadable as well.
