I forgot, are you knurling the bullets at all? No, I have not had to knurl for any of the loads using 4759 as booster. |

Great shooting. Also appears that your scope tracks extremely well.

Is this the first time you have shot this exact combo?
Looks like I may have to give it a whirl.

Is this the first time you have shot this exact combo? Looks like I may have to give it a whirl. A few posts down I shot the same total at 11/57 ratio. These loads have been very accurate. A few have expressed concerns about 2015 loosing some speed in cold temps, but is was tested at 12/48 volume. I will keep an eye on it as it cools next fall, but I really like it so far. For now I am working up to see where added booster affects accuracy potentials. I started at 12/58 but it was to much as sabots showed a lot of heat stress and twist in the petals and gas jetting was worse on the cup skirt. So I dropped from 70gr total to 68gr total and every load has shot with about same accuracy so far. The 4759 is where the accuracy is coming from tho, these same load types can be shot with extreme accuracy with H322. I will be shooting this same load of 4759/2015 at 13/55 and 14/54 in the next few days. Then will move to H322 as main to give work out but it shoots very similar to this. The key here is that it appears to me that 4759 is making approx 630 psi per grain as compared to N110 making in excess of 800 psi per grain but yet is only 3-4 fps per grain slower. (with the 200gr bullet weights) The "time to peak" is enough slower also as compared to N110 or 5744 either to aid with sabot integrity. IMO opinion 4759 is a MUCH better booster than any of the other powders I have tested so far in the .45 Hats off and many thanks to Edge for steering me this direction on the 4759. Mark |

Impressive indeed. Did you clock these things? dbinny I will have some speeding Reading on this load tomorrow.I was gonna have them Tuesday we got some rain and did not get to go. Mark Great shooting.  I will have some different load to test and get some speed Reading from it as well should be interesting. |

80 degrees. I can barely remember what that felt like. Soon here too I hope. Good reports, keep them coming. I want to try some of your best loads when my .45 barrel gets here. Your efforts will save a lot of work for me.

Now you need to try 5744 with those combo's. It also has less enery, grain for grain as N-110.

Richard 5744 tends to stress sabots at slightly less volume in warm barrels, due to it "quickness to peak" I think. I have noticed your's and TG's traces both represent this very well. 4759 seems to really "fit" the .45's. |

With that shooting, it is obvious that you are from Arkansas.
