EricP's Reloading Journal

[EricP]

• Dillon 650:
• 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.


Power Pistol - 5.0 gr.

Max	1092
Min	1058
Average	1075.4
StDev	10.47960983

Power Pistol - 5.2 gr

Max	1107
Min	1084
Average	1099.2
StDev	6.713171133
Ex Spd	23

* 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.

• Dillon 650
• 9mm
• Precision Delta 124 gr. FMJ
• Alliant Power Pistol:
• Dillon sizing, Redding or Lee seating, Lee Factory Crimp :
• CCI 500:
• 1.145"(COAL):
• See Table:
• General practice load:
• Power Pistol has an impressive flash:
• N/A:
• I've shot 10's of thousands of these. Will make minor power factor out of a 4" barrel:

Max	1068
Min	1028
Average	1046.2
StDev	10.25773136
ExSpd	40

* 20 round string, 5" barrel data

This is a much tamer load than the one above. Reducing COAL to 1.135 will tighten standard deviation and extreme spread. 1.135" will chamber in a my very short throated Shadow 2.
