uscbigdawg Posted May 25, 2004 Share Posted May 25, 2004 Hola, So I was running 124's in my Open gun and in a rest am getting just over a half inch at 50 yards (got to love Rusty Kidd). With the reduced power factor, the comp and hybrids are not working near as efficient and so I tried switching to 115's. The performance is spectacular. However, without having put in on a bench, but doing some plinking with the new loads, it seems as though the groups have opened up a bit. If I had to guess, somewhere around 3-4" at 25 yards. Now, I've heard this is a common problem with 115's and N350 and that a potential cure is switching to 3N38. Anyone else notice this and/or have a fix? The barrel: Scheumann Hybrid w/ 4 ports 1:32 twist. Thanks, Rich Link to comment Share on other sites More sharing options...
Nolan Posted May 25, 2004 Share Posted May 25, 2004 Rich, With 115 gr JHP the most accurate load out of my Open gun is AA#7 however I hate shooting the stuff. It stinks, is very abrasive, and has a very sharp recoil. Dot tracking and movement is pretty good. But with all that said try IMR 7625. Accuracy isn't quite as good as AA#7, but it is the softest recoiling powder I've tried. Dot tracking and movement are very good. IMR 4756 is my second favorite powder but I think it actually works better with 124 grain bullets. Nolan Link to comment Share on other sites More sharing options...
ErikW Posted May 25, 2004 Share Posted May 25, 2004 I went directly from N350 to 3N38 under MG 115 JHPs and didn't notice an accuracy difference. Of course, I don't have any extra holes in my barrel for the accuracy to leak out. Link to comment Share on other sites More sharing options...
Scout454 Posted May 26, 2004 Share Posted May 26, 2004 I've been using 115 Zero JHP's with N340 for over a year in a shorty. Works well, the dot tracks and I'm getting 3/4" or so at 50 (old eyes don't help). Mike Link to comment Share on other sites More sharing options...
uscbigdawg Posted May 26, 2004 Author Share Posted May 26, 2004 Scout, What are your groups like? Rich Link to comment Share on other sites More sharing options...
Scout454 Posted May 26, 2004 Share Posted May 26, 2004 Rich, I can cover 10 shots with a quarter at 25 yards. At 50 yds, for me (old eyes and a 7 min dot) it opens up to better than an inch (still under 2). Mike Link to comment Share on other sites More sharing options...
uscbigdawg Posted May 26, 2004 Author Share Posted May 26, 2004 Thanks Scout. N340 was another solution given by the same friend that suggested 3N38. I'll give 'em both a shot. Rich Link to comment Share on other sites More sharing options...
TheOtherErik Posted May 27, 2004 Share Posted May 27, 2004 Rich, what bullet are you using? I notice that get alot better groups with Montana gold as compaired to a winchester and remington. The montana has a larger bearing surface than the others. I never tried zero's Being that you have 4 hybrid ports you might to stick to the slower burning stuff. Im experimenting with 3n38 right now..shoots really nice but its a little dirty. Im not quite sold on it yet. 4756 shot really nice with 124's, but I dont think you can get enough in a case with 115's Link to comment Share on other sites More sharing options...
uscbigdawg Posted May 27, 2004 Author Share Posted May 27, 2004 So I just got off the phone with both Rusty and MV about my little situation. The concensus is that I need to try different powders. Not a problem. It gives my father a chance to shoot the Open gun (he gets a lot of gee-whiz at the range Plus he enjoys loading on a single stage ). TOE - I was/am using MGB 124 FMJ/CMJ's and getting .5" at 50 yards. So the potential is there. I'm switching to 115's to get the gas pressure up, but am not opposed to going back to 124's if I can increase the gas volume (i.e. slower powder). If I didn't run a ported gun, I already know a great setup. 115's and N105. It is NICE!!! So, looks like I'm going powder shoppin': N340, 3N37, 3N38, IMR 7625. The only crappy part is that I'm sittin' on 6 pounds of N350. I was really hoping a bullet switch would have done it. Oh well. Back to the lab. Boowahahahahah!!!

TheOtherErik Posted May 28, 2004 Share Posted May 28, 2004 good thing is that the IMR is avalible in 1/2 pounders. You wont be out too much if you dont like it. Link to comment Share on other sites More sharing options...
uscbigdawg Posted May 28, 2004 Author Share Posted May 28, 2004 Dude, I live in the country. We can get pretty stupid with surplus propellants! Just kidding........ Rich Link to comment Share on other sites More sharing options...
schmitz Posted June 11, 2004 Share Posted June 11, 2004 U, try this solution to get rid of your surplus N350 under a 115 Powder: 6.5 grains N350 (maybe add a little bit more because of the extra holes) Primer: WSP OAL: 31.8 mm/1.25" Case: REM +P Barrel: Schuemann 5.5" (no extra holes) Safe shootin' Henny.

uscbigdawg Posted June 11, 2004 Author Share Posted June 11, 2004 Hola Henny, Definitely no longer have a surplus of N350 (kind of in a drought though on 115's ). Powder: 8.6 grains of N350 Primer: WSR Case: Remington +P Barrel: 5.5" Scheumann w/ 4 hybrid ports and 2 "Viper" (a.k.a. RO eliminator) ports Flat, fast and a little loud.

schmitz Posted June 11, 2004 Share Posted June 11, 2004 U, Wow....8.6 (6.5 was my Bianchi-load) if available in USA, try the Fiocchi 115 FMJ's they're great! Safe shootin' Henny. PS. "A 'little' loud?? Link to comment Share on other sites More sharing options...

Dan Bone Posted June 15, 2004 Share Posted June 15, 2004 I've always been told that the accuracy of 115 (vs. 124's) was a function of the twist rate of the barrel. But I've never seen that it made that much of a difference (to me). I'm using 9.8 3N37 // SRP // 124 MG JHP with a Schueman Hybri-comp (LOTS o holes). It's plenty flat, plenty accurate, plenty loud and fills the case. It's highly recommended to double your hearing protection and keep your mouth clamped shut while shooting this load. Warning the R.O. is a nice courtesy as well. I can't go up to the 350 / 3N38 I'm almost a compressed load as it is. I would be interested in trying that 340 though. Can anybody make any claims of excellence with this combination? Link to comment Share on other sites More sharing options...
Scout454 Posted June 16, 2004 Share Posted June 16, 2004 Danny, I went 171 at the Blast with a 5fps spread. 115 Zero JHP's, 8.2 of N340, WSR, in a 4.5" Schuemann AET with a 3 port EGW comp. Remington 7 1/2's give me 1505 to 1515 with the same load. Mike Link to comment Share on other sites More sharing options...
Robert Snyder Posted June 16, 2004 Share Posted June 16, 2004 I am curious about anyone shooting a shorty with 115 FMJ's. As I have talked with Benny Hill and he said to load them to an OAL of 1.160. My first batch that I am loading is 6.9grs of 3N37 which I know will be more of a steel type load but I have N340 and N105 powders as well. I am trying to come up with a good starting point so that I can tweak it to match the gun and still make major. The FMJ's I have are Zero bullets. Thanks for any help!

Scout454 Posted June 16, 2004 Share Posted June 16, 2004 The 8.2/N340 load I referenced was in Super cases. I use N340 for steel too, but at a reduced load and with 125's. Link to comment Share on other sites More sharing options...
