  1. I would start out at around 4.2 grains loaded to about 1.165 OAL. You may have to increase or decrease a tad after Chrono but probably not much. For my 6 inch STI I use 4.3 grains of N320 loaded to 1.165 OAL using 180 grain Moly Coated Black Bullets. They Chrono at around 169.8 PF. The jacketed bullets want get as good a PF as the Moly Bullets so I think 4.2 grains would be a safe place to start.

  2. Basically any Accidental Discharge would be deemed grounds for a disqualification. It would be my assumption if a competitor is firing at a target and the bullet hits the ground 10ft or further out, the competitor was firing at that target and no accidental discharge occurred. It would basically be assumed if the competitor is firing at a target and the bullet hits the ground within 10ft it is an accidental discharge and unsafe, resulting in a DQ unless it is caused from the result of a squib.

  3. Thanks Roman! I'm just wondering how reverse sensitive the Silhouette is? Guess I will have to experiment with different temperatures, but that may take a while.

  4. Chrono Results: Temp 65 degrees in full sun. Shooting a 6in STI and 5 In SV

    40 caliber 180 Grain BBI loaded with 5.8 grains Ramshot Silhouette at 1.162 OAL

    6 inch gun power factor was 175.3

    5 inch gun power factor was 168.3

    Now using 5.9 grains of SR 4756 with same bullet and OAL

    6 inch gun power factor was 178.2

    5 inch gun power factor was 164.6

    6.1 grains of SR4756 with same bullet and OAL

    6 inch gun power factor was 180.2

    5 inch gun power factor was 171.8

    40 caliber 180 grain Montana Gold CMJ loaded with 4.5 grains of Tite Group at 1.165 OAL

    6 inch gun power factor was 173

    5 inch gun power factor was 168

    Recovery time was faster with the Silhouette than the SR4756. After I get all this powder used up, I will experiment with Solo 1000.

  5. Thanks Aaron! The problem I run into is trying to find a load that will not burn to fast and rip any of the moly off my bullets. If you load a real fast burning powder it seems like it leaves a little more residue in the barrel but then again you don't want a real slow burning powder either. Silhouette seems to work fairly well. I guess I'm just always searching for that perfect load, LOL.

  6. Thanks sargenv, sounds like an educated answer. I've got an open gun too so nothings lost. I'm still gonna chrono what I've loaded so I can feel just what your talking about when I shoot those loads.Interested to see how the Silhouette compares to the 4756 in a Major PF Load. I've looked at a couple of burn rate charts and one has Silhouette burning faster than 4756, then the other had 4756 burning faster than Silhouette. Thanks for your answer.

  7. Have been using 5.7 grains shooting 180 grain Black Bullets. OAL 1.165

    I'm gonna chrono tomorrow using the above load, also gonna try 5.9 grains and 6.1 to see what I will need to make MPF.

  8. Does anyone out there use SR4756 for a 40 caliber Limited Load? If so, has your experience been a positive one or should I look at loading with a different powder. I also use Ramshot Silhouette. Most people tell me SR4756 is a good Open Gun Powder but seem a little surprised when I tell them I'm using it as a Limited Gun Load.
