SP BULLETS TECHNICAL DATA Should you need any information regarding load development and suitability for specific cartridges which are not to be found on this page please e-mail us. Click here for the standard CIP and SAAMI specifications. Notes Our bullet numbers are composed as follows: The first three digits denote the caliber(172). The next three digits give the weight in grains(017). The two letters indicate the type of bullet (SP) and the last three digits, the part number(162). It is important to match the bullet correctly with the twist rate of your rifle and with the intended range distance in mind. This is more likely to ensure good ballistics than the traditional, but unscientific, method of choosing a bullet by weight. Click on the BULLET NUMBER for more information about the particular bullet. Any blank blocks indicate that the data is not yet available. Please contact us if you need any such information. |
