Albertl35 Posted April 19, 2011 Share Posted April 19, 2011 (edited) 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 4 1272 1306 1335 5 1274 1308 1337 6 1277 1311 1339 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 Edited April 19, 2011 by Albertl35 Link to comment Share on other sites More sharing options...
KUJayhawk01 Posted April 14, 2020 Share Posted April 14, 2020 (edited) 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.

Diffusers installed. 7 gr will give you about 1400 fps, that's what I use.

KUJayhawk01 Posted April 17, 2020 Share Posted April 17, 2020 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. Link to comment Share on other sites More sharing options...
