tpe187 Posted January 20, 2006 Share Posted January 20, 2006 (edited) Hi All, Just got back from the range and some more load development. I figured I would post the results here, to maybe help someone else out. Load 1 - Pistol SVI Comp gun with Schuemann 5.5" barrel and 8port Comp (4top, 2each side at end) Powder VV3N38 - 9.3gr Bullet - 115gr Zero HP Primer - Winchester Small Rifle Brass - Remington Nickel 38 Super +P marked Loaded to 1.22 OAL with .379 crimp 10 rounds fired 7ft from Chronograph (PACT XP Pro) Hi 1348 SD 13.8 Lo 1308 AVG 1335 PF153.5 Load 2 Powder VV3N38 - 10gr Bullet - 115gr Zero HP Primer - WSR Brass - Remington Nickel 38 Super +P marked Loaded to 1.22 OAL with .379 crimp 10 rounds fired 7ft from Chronograph Hi 1404 SD 19.3 Lo 1352 AVG 1378.9 PF 158.4 Load 2 out of 5" Kart Barrel in STI limited gun Hi 1462 SD 23.2 Lo 1370 AVG 1402 PF 161.2 Notes: I was surprised how little gain in velocity there was going from 9.3grs to 10grs in VV3N38. Accuracy was fairly good at a little over an inch at 25yds for five shots from a sandbag with both the SVI 5.5"and STI 5" Load 3 Powder IMR 7625 - 7.9gr Bullet - 115gr Zero HP Primer - WSR Brass - Remington Nickel 38 Super +P marked Loaded to 1.24 OAL with .379 crimp 10rds over Chrono Hi 1445 SD 11.4 Lo 1410 AVG 1427 PF164.1 Load 4 Same as load 3 but OAL is 1.23 Hi 1435 SD 9.4 Lo 1406 AVG 1424.8 PF163.8 Load 4 out of 5" STI Hi 1462 SD 9.6 Ll 1432 AVG 1454.2 PF 167.2 Notes: This load was really accurate at about an inch at 25yrds, which is probably limited by me, not the gun. This load feels slightly softer than the 10gr 3N38 load which clocked 50fps less. Since IMR 7625 is way cheaper than 3N38 and the SD's were much lower, I think I will use it for this gun/bullet combination. I'm just going to tweak the load about .3grs more in 7625 to make sure I make major. Temperature was 65 degrees for all chrono results. All rounds loaded on a Dillon 650 with Redding Competition Seating die. Tom Edited January 20, 2006 by tpe187 Link to comment Share on other sites More sharing options...
TMC Posted January 20, 2006 Share Posted January 20, 2006 What was the charge weight for the 7625 load? Link to comment Share on other sites More sharing options...
tpe187 Posted January 20, 2006 Author Share Posted January 20, 2006 Oops, sorry I missed that. It was 7.9grs. I'm going to try 8.2 to make sure it makes major and I'll post back what I get. Thanks Link to comment Share on other sites More sharing options...
tpe187 Posted January 21, 2006 Author Share Posted January 21, 2006 Hello All, Just wanted to post an update on the 38 super load with IMR7625. 8.2grs loaded to 1.23 OAL, crimped to .378 with a 115gr Zero JHP,WSR primer, Rem Nickel 38 Super Brass AVG 1472.6 for 10 shots, 7ft from Chrono SD 5.6fps ES 18.3 PF 169 at 65 degrees Accuracy 1" at 25yds from sandbagged rest out of 5.5" SVI with Schueman Barrell Link to comment Share on other sites More sharing options...
fastshuter Posted August 18, 2006 Share Posted August 18, 2006 I have tried some of your loads listed here. With mixed results of course. I find that loading it to 9.1 grains of 7625 gives me better hits. I could shoot over sandbags but I think the real test is getting out there with the rest of the gang while practising. I used mixed brass, winchester small pistol magnum primer, 115 gr MG fmj, oal 1.255 I just chrono'ed the same load yesterday morning using Starline and Remington NP and found that the velocities were a bit higher with NP. About 30 fps. When it warmed up later in the day, about 10 degrees celcius, the loads were closer together velocity wise anway. About 13 fps difference higher with NP. The Starline loads remained about the same. Just what I have been seeing here anyway. Starline PF 175.9 REM NP PF 177.5 Link to comment Share on other sites More sharing options...
XRe Posted August 18, 2006 Share Posted August 18, 2006 Just FYI - in my gun, it looked like I was going to need in the neighborhood of 11.0-11.6gr 3N38 to make comfortable Major w/ a 115gr bullet. Its a slow powder, so a couple of tenths won't make a huge jump in velocity. Same gun made 164.1PF with 8.4gr 7625 (keeping in mind that 7625 tends to vary by lot).

AzoneHits Posted January 21, 2007 Share Posted January 21, 2007 Hello All,Just wanted to post an update on the 38 super load with IMR7625. 8.2grs loaded to 1.23 OAL, crimped to .378 with a 115gr Zero JHP,WSR primer, Rem Nickel 38 Super Brass AVG 1472.6 for 10 shots, 7ft from Chrono SD 5.6fps ES 18.3 PF 169 at 65 degrees Accuracy 1" at 25yds from sandbagged rest out of 5.5" SVI with Schueman Barrell Did you like it over all compared to the 3n38 VV powder. A friend of mine told me that the vv 350 is violent and that is what i'm using now. I'm in the process of switching powder and have heard the IMR powder is a good one and cheaper too.

tpe187 Posted January 21, 2007 Author Share Posted January 21, 2007 TomAre you seeing little cooper half moon shaped shaving from the bullets? I don't recall seeing half moon shapes of copper. Its been awhile since I broke out the SVI in .38super. I've been shooting .40 in limited. I really liked the soft feel of Viht 3N38, but I couldn't justify the price and it was not readily available. I found I had to place an order with powdervalley.com, just to make some rounds. Much easier to go to the corner store and pick up lb of 7625. Definately worth trying if you like to experiment a little. Link to comment Share on other sites More sharing options...
eric nielsen Posted January 21, 2007 Share Posted January 21, 2007 Those are both good powders for the 115 Zero which is the bullet I use too. My gun needs 8.6gr of 7625 or 10.3gr of 3n38 to get to the same 170pf. Really like the feel of 7625 but the case-head expansion is much worse. Brass is only good for 3 or 4 firings. With 3n38 or Vectan SP2 or HS6 the brass is still good after 8-10 firings. 10-year-old 5" Nowlin barrel with no holes & not a lot of rifling left, either. If I use all the same brand of brass it groups 5/8" at 25 yards. Link to comment Share on other sites More sharing options...
joecichlid Posted January 22, 2007 Share Posted January 22, 2007 Rifling? From what I heard your Open gun isn't broke in if you still have rifling left. Joe W. Link to comment Share on other sites More sharing options...

A friend of mine told me that the vv 350 is violent and that is what i'm using now. I'm in the process of switching powder and have heard the IMR powder is a good one and cheaper too. N-350 is in between 3N37 and 3N38 IIRC. I have used N-350 for years now. It is the powder I always come back to after trying something else. It's not "violent" in my 5" barrel, 6 ports straight up comp top end. FM Link to comment Share on other sites More sharing options...
