LOAD PROCEDURES AND DATA

QUESTION:
Can I use load data from other manufacturers as a guideline for loading GS Custom Bullets?

ANSWER:
Yes, with certain precautions.

Use only load data from powder manufacturers when applying the guidelines below.

HV and FN bullets develop lower pressure levels than conventional bullets. Any load, from starting loads to maximum loads, that is safe with a conventional bullet of similar weight to an HV or FN bullet, will be safe to use. Note that this does not apply to bullets made by other manufacturers, especially bullets with grooves in the shank, instead of drive bands. HV and FN bullets can be loaded to higher speeds than jacketed bullets. See the load data pages for more detailed information.

HP bullets should be loaded with more caution. Any recommended starting load for a conventional bullet of similar weight, is safe as a starting load with an HP bullet. When working up a load, check what the recommended speed for a conventional bullet of the same weight is, using the same powder. Stop when that speed is reached. HP bullets cannot be loaded to higher speeds than conventional jacketed bullets. 

QUESTION:
How do I estimate a starting load with HV and FN bullets if I load for a wildcat where you cannot supply load data?

ANSWER:
A good rule of thumb that has never failed with HV and FN bullets is to take the max load for a jacketed bullet of the same weight and work up from there. HV / FN will give slightly lower speeds for the same powder charge than jacketed bullets, but pressure is much reduced. If you used a normal starting load with an HV, you would feel the difference in recoil and sometimes the cases do not even seal properly. By the time pressures are at the high end, HVs are moving considerably faster than standard bullets.
