Evoc One, EtAl.,
For years I've been of the mind, for pistol cartridges at least, that I can do it all with Bullseye, Unique, and 2400. However, working with 2400 and H110 side by side, I have to say H110 gives lower PRESSURE signs than 2400 when loading to the same velocity. Approaching max loads with 2400 I get flattening of primers, while with H110 I have yet to see flattening of primers. Also, H110 has reduced flash and muzzle blast compared to comparable loads with 2400. You will also note the the Speer and Hornady 180gr .358 bullets do not seat as deeply in the case as their 357 silhouette bullets do, further reducing pressure with comparable powder charges.
