The following items constitute our standard products: though even these standard items are made to order – CUSTOM MADE – occasionally, we will have a few bullets of one or more items on hand; it never hurts to check.  Call 515-438-4010 or, e-mail bibrob@minburncomm.net

Along with the bullet descriptions, are listed the “ideal” twist rates: these twists will impart a gyroscopic stability factor (Sg) of 1.5, calculated at sea-level, Standard conditions and 3,000 FPS muzzle velocity. For a specific bullet,  twist rates which impart between 1.4 and 1.9 Sg will provide the best precision. While faster/slower twist rates may work well enough, twist rates which produce Sg outside this window begin to errode potential precision.

To provide a comparison with mass produced bullets, the BCs are calculated for 3000 FPS muzzle velocity, at sea-level and Standard conditions, using the G1 drag function. (Note: this is the function used by most of the brand name makers.) Based upon experience, REAL world BC will vary, and will usually be 0.015 to 0.020 LOWER than calculated. (Note: for those who use ballistics programs capable of computing trajectories using the G7 drag function, the G7 BC s are posted in RED – even for FB bullets, out to 600 Yd., the G7 provides a better “fit” than the customary G1:  BC, using the G7 model,  is markedly less velocity sensitive:  i.e., BC is relatively CONSTANT over a range of velocities.)

Bullet Details: all are TANGENT ogive configurations – dimensions are the NOMINAL, or, average diameters produced by these dies from [jacket] Lot-to-Lot, shank diameters will be very constant; pressure-ring (heel) diameter my vary up to +/- 0.0002″.
