I have been working with savage shooter on some duplexes and single powder loads to try to get a powder that has low es and around 2800 and also have low pressure and will keep sabot in tack.I had some n130 in my gun safe and me and mark got to talking and we decided to give it a try as a single and see what it was capable of making for velocity.note I look back at some of Richard post and found were he shot it at 55 gr and found some pressure traces on it so me and mark done some more talking and we decided to run some across the chrono graph and see what speed was.I have a place I can do speed reading but not no distance so I started at 65 gr it gave me 2675 fps it making 41.15 per sec per grain then 68gr it gave me 2750 fps it was making 40.44 per grain and 70gr give me 2840 fps it was making 40.57 per gr.now it time to go to the range and test this load to see how it goes here what we ended up with.I shot the 70 gr the first 2 was about 2 and quarter inches apart I said okay good let shoot 3rd made group 5 inches.I then try-ed 69 gr with and with out a wool wad.here what we got.   Note this group is 5 inches I then wanted to load up 3 shot and shoot them as fast as i could to see what would happen.All shot was at 200yards  Note: I also talk to Dave d about it and also ask edge to run quick load data on this for me thanks Allot. Note: up coming test is to put the gun in a deep freezer and leave it and get the gun down to say 10-15 degrees and then pull the gun out real fast and shoot it across the chrono and see how much velocity i loose.  |

Interesting test Shooter..............! What happened to shot #4 on the first target? I see it was the one shot that spoiled a very low ES? Off the target? Shots 1,2&3 printed a nice group. In my opinion, a low ES is the key to good groups. In group two, shot #3 was the fastest by almost 100 fps and it went out to the left. I have experienced the very same situation??? The extreme change in velocity caused shots to go wide from the others  Group #3  ? The third shot was the highest and I would say out of the group. You also did not mention if you used the wool wad on this group? It appears the wool wad did not help Personally, I would drop the N-130 to 55 gr. and kick it with 10 gr. of N-110. It should get you to about 2800. It will also assure you of good ignition. As much as I have tried single powders, with the exception of H-4198, better results have come from duplexing or triplexing. If you look thru the hundreds of different loads I have run thru my rifle, the most consistent have been duplex and now, triplex loads. AND as you could see from pressure traces I ran, similar velocities can be had at lower pressures with a duplex vs. a single. And triplex loads also showed much less pressure. Do yourself a favor and try 10/20/34 of N-110/N-120/H-322 with a 200 gr. SST or XTP or even the 195 Barnes. I have shot this combination quite a few times and it always produces good results in the upper 2700 fps range. Richard Richard |

Richards,that was a miss chrono reading.I actually number that wrong 3 should have been number 2 my bad.On the last shot i wanted to shoot three with out the wad as fast as i could shoot. these was shot with in 3 mints the barrel was really hot.  |

Richard Richard Richard ,I believe that I have studied and read as much as anyone could in the short time I have been here in order to learn and I know I am a big PAIN in the A@# to some. Hope I will be able to contribute someday but for now I have another question. You stated you have shot singles as much as anyone WITH the exception of H4198. Some say this is the best single powder out there. Please give it a fair chance. There are those of us that cannot do the testing you and others do so we depend on you guys:) Rusty |

Rusty..................Knock your socks off if you want to test it! I'm not telling anyone what to test or not to test? Where did this come from? Shooter can test what ever he likes? I can tell you this, from what I have heard, V V is not producing N-130 anymore. This was their original benchrest powder for the 6mmPPC..........then they came out with N-133 and everyone pretty much switched to it. It is presently the powder of choice for 90% of the PPC shooters. You will note, I do more testing with H-322 than N-130 because there will come a time when the market dries up. So, my thought is, why do a lot of testing and then find you can't get the powder? I happen to have about 6 lbs. but thats it.

:)buddy the first two targets look good. Take one or two out and they are super. Vn130 might be another single to explore. Have fun ringing it out.

Shooter...............That is good to know. I have not seen it in the shops we visit and I never see it listed with some of the big suppliers. Our friend Bill said he heard it was discontinued? I guess it pays to got to the source Still think its on the slow side as a single!...........Kick it with some N-110 and it really comes alive Richard |

This is at 200yrds |
