After doing countless 9mm/40S&W/45ACP load testing for Herco threads, I decided to change gears and have some fun with 380Auto.
Tula 91 gr FMJ ammunition and X-Treme 100 gr RNFP plated bullets were used with W231/HP-38 and Taurus TCP 748. Although longer length passed the barrel drop test, 0.945" OAL/COL was used for the test that reliably fed/chambered from the magazine.
After referencing Hodgdon load data, 2.6/2.8/3.0 charges were dropped from Lee Perfect Powder measure and verified on Ohaus 10-10. Hodgdon lists 3.1 gr as max charge for 100 gr FMJ with 0.980" OAL/COL. Since X-Treme's RNFP plated bullet loaded shorter at 0.945" due to the flat nose, I only used 3.0 as max charge.
Range Test:
At 7 yards, Tula 91 gr FMJ factory loads produced snappy recoil typical of 380Auto with short barrels and greater than 2" shot group.
X-Treme 100 gr RNFP W231/HP-38 loads produces less snappy recoil (I decided to use 10/10 scale for Tula factory load):
- 2.6 gr under 1" group (4/10 felt recoil)
- 2.8 gr 1.25" (6/10 felt recoil)
- 3.0 gr 1.25" (8/10 felt recoil)
Now that we have a reference baseline, I am planning to test other powders and bullets (I have 95 gr Montana Gold JHP) and perhaps at greater distances as well.
