GS CUSTOM BULLETS - Load Data for SP Bullets

Read the following notes before going to the load data table below.

Calibre: If your caliber is not listed, please email us for assistance.

Bullet: Bullet numbers consist of the caliber (270) the weight (099gr) the bullet type (SP) and the part number (217).

Twist: The twist is indicated as one rotation in the number of inches shown. Bear in mind that if a bullet is indicated for a particular twist, it can also be used in faster twist rates (smaller numbers), but not in slower twist rates (bigger numbers). See the Technical Data page for more information about the correct bullet choice.

Powder: Listed powders are chosen to give a combination of the best case fill, most complete burn in a 24"barrel and lowest muzzle pressure.

Start gr: The indicated start load in grains is a safe load in our experience. It may give maximum speed in some rifles and can be reduced if needed.

MAX FPS: This is the speed at which maximum allowed pressure is likely to occur in a 24" barrel. Adjust the number by the amount given in the FPS/Inch column for barrels longer or shorter than 24". Do not exceed the adjusted MAX FPS number. Whatever charge is required to reach the MAX FPS is the maximum charge for that rifle.

FPS/Inch: This is the speed change that is probable for barrels longer or shorter than 24" with the indicated powder.

Case Fill: Is approximately how much the charge will fill the case. Compressed charges up to 105% are not unusual. Full cases give better accuracy and more consistent speeds. This is a guide line only and the numbers may vary depending on the make of the case and the capacity. If this column contains CC, case capacity will probably be the limiting factor rather than MAX FPS.

Burn: Is the percentage of powder that will burn in a 24" barrel. Accuracy is improved with a more complete burn.

M/PSI: Is the approximate muzzle pressure at MAX FPS. This is an indication of what the recoil will be. With the same bullet and rifle, lower muzzle pressure will have less recoil.
