I have loaded and shot at least 12 pounds of N110 over the years in 357 Magnum and Ruger-only 45 Colt. If you are getting unburned powder then your load is definitely too light, when properly loaded N110 is super clean. 19 grains is just one grain less than I load 125gr JHPs in 357. According to my Vihtavuori 3rd edition manual starting loads for 240gr Hornady JTC-Sil is 19.8 grains and max is 21.9. A firm crimp and more powder will give you a cleaner burn, which it looks like you have done. I have loaded compressed loads in 357 while still being within published data with no problems at all. Being an extruded powder N110 can be compressed, unlike most ball powders. That is one of the things I like about N110, you can't seem to get enough of the stuff into cases and still seat bullets to get you into trouble. Speer uses standard primers with their N110 357 data and magnum primers in 44 Magnum. Vihtavuori states large pistol or large rifle in 44 Magnum and small rifle in 357 Magnum. They don't publish data for Ruger-only 45 Colt but Speer does and used the CCI300 standard primer with N110 while Sierra used the CCI350 magnum primer. I worked up my 357 and 45 Colt loads with CCI550s and 350s. I think N110 will work well with any primer; standard pistol, magnum pistol or rifle. Just don't substitute hotter primers in loads you've worked up with weaker primers without dropping back and working up again. N110 is perhaps the best all-around powder for magnum pistol cartridges. Too bad it is so much more expensive and hard to find and no longer available in bulk.
