jsg Posted November 15, 2015 Share Posted November 15, 2015 Anyone have a good starting place for HP-38 in short colt? I have bullseye and titegroup to try but would rather use HP-38 since I have more of it. The search brings up a few suggestions for BE and TG but no 231/HP-38. I will be using a 158 Extreme plated and 160 BBI for testing in a new 627. I will be running them over the chrono as I test and looking for PF of 130.

Toolguy Posted November 15, 2015 Share Posted November 15, 2015 (edited) I am running 3.0 HP-38 in short colt with 160 gr. polymer coated bullets. I don't know the PF but it is accurate and takes down steel pretty well. I'm estimating it's in the 800 - 850 fps range. That would make the PF 128 to 136.

jsg Posted November 15, 2015 Author Share Posted November 15, 2015 Thanks. Seems like 2.8 is the starting point for all three of my powders. What overall length are you using? Seems 1.18ish is popular for the 160 round nose. Link to comment Share on other sites More sharing options...
jsg Posted November 16, 2015 Author Share Posted November 16, 2015 (edited) Little info for anyone tinkering with short colt. The following is the data I got today. Shooting over my f1 shooting chrono at 5 paces. All rounds were 1.130 oal 158 xtreme plated Win small pistol primer 55 degrees, avg humidity, sunny New 627 pc New star line brass 3.0 titegroup 700 fps avg 110 PF 2.8 bullseye 621 fps avg 98 pf 3.0 bullseye 668 fps avg 105 pf So I think I will see about .2 more powder as well as trying the 160 BBI bullets. Seems .2 isn't going to cut it with the xtreme bullet at this oal. Maybe HP-38 will fare better... Edited November 16, 2015 by jsg Link to comment Share on other sites More sharing options...
mchapman Posted November 17, 2015 Share Posted November 17, 2015 I am using BE-86 in my short colt loads, using a 150 gr. TC PC'd cast bullet OAL 1.125 and am getting 880 fps ave. This is with 4.1 grs. of powder. Link to comment Share on other sites More sharing options...
mchapman Posted November 17, 2015 Share Posted November 17, 2015 Longshot also works well, I've been using 9mm data for 147 cast and working up my loads and they seem to do ok. So far any of the powders and loads that I have tried for the 9mm, with a 147 gr bullets works ok to make minor PF. Link to comment Share on other sites More sharing options...
jsg Posted December 31, 2015 Author Share Posted December 31, 2015 Little more info... 160 BBI 3.2 HP-38 1.185 oal Win SPP Starline brass same equipment and placement as above 814 fps avg 131 PF 158 xtreme at 1.1 oal with 3.2 Hp-38 still doesn't make 125 Link to comment Share on other sites More sharing options...
sbo76 Posted December 31, 2015 Share Posted December 31, 2015 One more: 160g bayou rn 3.4g IMR PB (very very close to vit n320) 1.200 oal Starline brass Avg 834.75 PF 133.56 No overpressure signs Shoots very soft and was accurate at 25yds. The heavy bullet really does a good job on steel. Link to comment Share on other sites More sharing options...
