Great shooting Mark!!!!! In my notes a 12/58 N110/2015 avg. 2864fps @ 40* with the 195BX. I am going to guess your load will be a little slower with 4759 as the booster. On a sour note, the 12/48 N110/2015 duplex I used to shoot, 2690fps @ 35*, lost approx. 250fps when the temps dropped into the teens.  |

Great shooting Mark!!!!! In my notes a 12/58 N110/2015 avg. 2864fps @ 40* with the 195BX. I am going to guess your load will be a little slower with 4759 as the booster. On a sour note, the 12/48 N110/2015 duplex I used to shoot, 2690fps @ 35*, lost approx. 250fps when the temps dropped into the teens. Do you think the load level is high enough to keep this load from falling out on speed at cold. I estimate the N110 @ 12/48 was only making about 30K. The N110 @ 12/58 was making about 34K. Using the 4759 @ 11/57 should be making between 31.8K and 32.3K. This load should be "in between" the 2 you mentioned on pressure. On average I am seeing N110 make about 57fps and 4759 make about 54fps per grain. 2015 is averaging between 37 - 38fps per grain. Deducting from your N110 @ 12/58 load::::: 11gr at 3fps difference plus 57fps (11vs12gr booster) = minus 90fps. Then 1gr (57vs58gr) = minus 37fps. I would predict this load at minus 127fps from your N110 @ 12/58 @ 2864 minus 127fps = 2737 estimated speed to confirm. Right in line with what thought speed to be. Now question is will this load lose speed in the cold or do I need to be looking a bit more booster at the 12grs? It sure does shoot good at the current ratios. Thoughts? |

:)mark very nice shooting. Im with Dave 2015 has been know to be temp sensitive. I would think you would need to boost it up quite a bit to stabilize it. I see you are having a lot of fun with your new toy and thats great because I like seeing targets so keep em coming ;D.
