9mm Major Load Data

[Albertl35]

I have tried Autocomp on my buddy's gun and did not like the impulse that it had. I have been using Silhouette 7.9gr but have ran out and have N350 so loaded up some to try on my Sailor's Custom, 5in gun with 2 holes in the barrel. I liked the recoil impulse - sharp but flat. The load is slightly compressed. Chrono results below with PMC brass and WSR - primers looked really good. I am going to try 7.7/7.8 next.

Shot 7.0 7.4 7.6

1 1253 1300 1334

2 1270 1301 1314

3 1272 1305 1321

7 1280 1313 1344

8 1281 1314 1346

9 1281 1319 1347

10 1284 1323 1349

ES 31 23 35

AVG 1274.40 1310.00 1336.60

SD 8.86 7.47 11.42

7.6gr gets 168 PF

Bullet is 125gr Zero JHP, OAL = 1.175

HI. 

 

Last post from 2011. Nice. I love searching before posting. Thanks for major load data!

 

Odd cuz I have 124gr FMJ RN from Hornady #35577B. Hornady manual says max is 4.9gr for Autocomp = 1050 fps. 

I did 4.8-4.9gr, seated to 1.150" per manual.

CZ Shadow 2, stock, so 4.89" barrel, no ports.

Temp: approx 40 F, but i loaded it in room temp, approx 67 F. Kansas elevation, if this matters.

FPS:

1110   1124

1117   1121

1108   1295

1118   1103

1110   1312

1160   1652!! (380 case! mixed with my 9mm. No signs of high pressure. I wish i took photo but i chucked the case away after inspection)

1108   1070

1128   1096

1108   1075

But these velocities are at 4.8-4.9gr. There are more figures but it's consistent around low 1100s

 

 

5.2gr of WAC, seated to 1.150 as well. Same Hornady #35577B bullets.

1299    1318                       1302

1311    1302                       1295

1313    1300                       1302

1311    814? (sunny day)  5108 (bad measure)

1300    1101? (same?)      742   (same?)

 

 

Traded a fellow shooter my reloads for five PMC factory 124 gr FMJ. It says "1110 fps" on the box.

1052

1084

1080

1085

1072

 

Hornady LNL auto progressive. Competition Electronics ProChrono #CEI-3800.

 

Couldn't imagine what 7 grains+ of Autocomp will get me. Check out that .380 auto FPS! Primer looked curved. No pierce or extrusion. Rim looked good after extraction. So hot!

 

Approx 4 ft from chrono. Diffusers installed.

7 gr will give you about 1400 fps, that's what I use. (my reloading manuals are spider nests)

I just wanted to add this for new reloaders, as i imagine the experienced already knows:

 

My higher velocities with lower charges of Autocomp are likely the result of seat depth to 1.150", which is manual specification for this bullet, which is higher pressure. I think Markcic said he was seating his to 1.2", with many seating to 1.170"

 

Around 1.165" it was causing feeding issues in my G19.
