will do; trick is finding the right data for the XDS 3.3 compact, specifically.
Goal is to have a 100% powder burn prior to the bullet leaving the barrel, with the right velocity, an NO overcharge.
Use the hodgdon data at the low end of the range and get a chronograph so you can see the velocity. Most all pistol powders are fast and they should all burn without any problem in that barrel.
Data from the powder manufacturers is reliable. Other sources may not be.
What makes you think that you are overcharging?
