When comparing the .277 Wolverine to the 300 BLK, the 300 BLK has more options for the heavier sub-sonic bullets (168-220 gr), but when shooting the lighter super-sonic bullets (90-130 gr), the .277 Wolverine has a greater variety of better options, with each having an excellent ballistic coefficient (for hand-loading, .277 bullets are ...
The 160 gr (10 g) bullet which has a sectional density of 0.328 is similar in sectional density to a 220 gr (14 g) .308 caliber (7.62 mm) bullet. As sectional density plays a large factor in penetration, the .264 caliber (6.5 mm), though a diminutive caliber from a North American point of view, has had excellent results in the field.
The energy delivered by most 9mm loads allows for significant expansion and penetration with premium hollow-point bullets. Illinois State Police , border patrol , Federal Air Marshals , and United States Secret Service favored and used 115 gr (7.5 g) +P+ 9mm loads at 1,300 ft/s (400 m/s) for years with excellent results.
