- 9mm:
- S&S Casting 135 gr. Round Nose, Coated
- Alliant Powder Pistol, 4.8-5.2 gr.:
- Dillon sizing, Redding micrometer seating, Lee Factory Crimp:
- CCI 500:
- 1.150":
- See chart:
- USPSA and general practice ammo:
- Power Pistol has a pretty impressive flash.:
- Coated lead bullets need more case expansion then the jacketed Precision Delta bullets that I have used for years. Lack of data on 135 gr. bullets:
- Knocks down steel with authority.:
As mentioned above, there isn't a lot of published data on 135 gr. bullets in 9mm. I averaged 124 and 147 data, compared it to a spreadsheet I found on Brian Enos, and used a fairly forgiving powder. No pressure signs were encountered. I would say that this is a pretty warm load at 5.2 gr. and hotter than I was expecting.

* Chrono data - 10 round strings
I loaded 200 rounds for a USPSA match on Saturday at a reduced load of 4.8 gr. I don't have chronograph data on that. The trend line on the chart above says it should be about 1050 fps. This is still ~125 fps faster than necessary for minor power factor, but I won't have time to chronograph a new load before Area 7 this coming week. I will not have any concerns about the chrono stage.
Further load development is necessary.
