Barrel Bore Diameter: 0.300" 7.620 mm The diameter of the barrel from land to land.
Barrel Groove Diameter: 0.308" 7.820 mm The diameter of the barrel from groove to groove.
Bullet Weight: 130gr 8.4g Bullets are guaranteed to weigh within a quarter percent of the stated weight.
Bullet Length: 1.17" 29.680 mm
Secant Ogive Length: 0.63" 16.000 mm These dimensions are critical to consistent external ballistic performance and are held constant to within 0.005 mm (0.0002")
Meplat Diameter: 0.09" 2.200 mm
Min Bullet Protrusion: 0.71" 18.060 mm Add the case length to these numbers to determine the maximum and minimum cartridge overall length that is possible with this bullet.
Max Bullet Protrusion: 0.83" 21.000 mm
Bullet conforms to CIP and SAAMI for magazine length. Case and COL based on: 308 Win. Check the COL of your rifle for suitability with this bullet as described above. Check the magazine length of your rifle for suitability with this bullet.
Maximum M/V: 4000fps 1,219 m/s If the maximum muzzle speed is exceeded, dynamic stabilty problems may be encountered.
Minimum Impact Speed: 1600fps to 1700fps 488 m/s to 518 m/s At this impact speed, the bullet will open to at least double caliber.

Twist Rates are guidelines but the Minimum Twist must be observed 
Twist: Sg = 1.4: 12.2" / 311 mm 40.8 Calibers General hunting twist for average distances to 420 yards or 390 m. A tighter twist (smaller number) can be used.
Minimum Twist: 14" / 355.6 mm 46.7 Calibers The slowest twist required for stable flight and good terminal performance further than 420 yds or 390 m. See 'Notes' below.

Calculated Ballistic Coefficient - Standard Metro G1 profile. Based on: Cd = 0.259

BC = 0.361 Maximum M/V to 2800 fps Maximum M/V to 853 m/s Any comparison with the BC values of other manufacturers is not valid as there is currently no standard method in use between manufacturers.  These BC values are only for use in an external ballistics program. Use the three values, as given, to approximately calculate BC for your launch speed and distance. For exact numbers, shoot drop tables at the elevation and temperature for your location.
BC = 0.321 2800 fps to 1600 fps 853 m/s to 488 m/s
BC = 0.316 1600 fps to 0 fps 488 m/s to 0 m/s

Suitable Cartridges, with consideration of the above specifications:

7.62 UKM, 7.82 Warbird, 30 Court Cartry, 30-60 Spring., 300 Lapua Mag, 300 RUM, 300 Savage, 300 WSM, 308 Win, 300 H&H, 30-378 Weath Mag, 300 Weath Mag, 300 Win Mag, 308 Norma Mag, 30 R Blaser, 30 Super Fl. H&H, 30-40 Krag - Use the specification sheet above to determine whether this bullet is suitable for the cartridge that you want to use.

NOTES
A Gyroscopic Stability (Sg) greater than 1.1 is required for stable flight with HV and HP bullets. For hunting under 420yds/390m, an Sg of up to 1.4 or more can be used. For longer distances the Sg can be decreased but never less than 1.1.
*Note that Sg increases as twist tightens.  *A 1:10" twist is tighter than a 1:12" twist within a given caliber only. *Twist rates given in caliber lengths can be compared across calibers. *Choose a bullet length best suited to your rifle twist and type of shooting.  *When a bullet is specified for a given twist rate, it can also be used in any twist that is tighter.  Using it in a slower twist than specified, is not advisable. *Some experimentation will be required to determine exact drop tables for your equipment and location.
