"Triple Shock X-Bullet Loading Guidelines
At this time we don't have specific load data for the Triple Shock X Bullets. However, here are some loading guidelines to use with X Bullet load data.
1. What load data do I use for the Triple Shock Bullet?
Answer. We recommend that you use the minimum X Bullet load data to start.
To compensate for the reduced pressures associated with the Triple Shock, you may have to work up 1 to 2 additional grains above listed loads to achieve equal pressures. Pressures can jump dramatically; therefore we recommend that you work up in 1/2 gr. increments until you are no more than 1 to 2 grains above the listed max load or until signs of excessive pressure are evident. Whichever comes first. You should watch for excessive case head expansion, sticky bolt lift, flattened primers or shiny spots on the base of the case. If you have case head expansion of more than .0005" with a once-fired case, this is a sure sign of excessive pressure. You will have to measure your case head with a Blade Micrometer just in front of the extractor groove, or you can use a regular micrometer and measure the belt on belted cases, before and after shooting. When any of these signs appear, back down one full grain and you will have a max load for your gun.
If you do not feel comfortable working up a load, or don't have the proper equipment, then we suggest following the recommended X-Bullet load data. For the 168gr .308 cal Triple Shock Bullet, use the 165gr X-Bullet data."
PM me your email and I can send you the data for regular x-bullets in a pdf.
Nosler data I don't have with me. I will check here tonight and see if you have the info and send it if you don't.
