However, if you have standard and magnum primers, try both. I've used HS-6 for a good while. Much like Power Pistol, it seems to be a good powder in specialized applications. It's not a particularly versatile propellant, but it probably wasn't designed for that purpose.

Unless you have a chronograph you can't say using a magnum primer makes no difference. With standard primers the ES and SD numbers are high and most times shrink to single digits with magnum primers. It is more noticeable with lighter loads since HS-6 performers better at the top end of the pressure range.
This is why when we want to produce a midrange load we go to a faster powder instead of lightening up the slow powder load. We can achieve our goal but keep the pressures up insuring a cleaner burn. Most powders will perform better at the top end of the pressure range.
