RE: What distance to sight in???
Well for starters what is your maximum distance you want to hunt? That plays a big part in it. You also need to find out what your gun is capable of at different distances for grouping. Just because you think your load will shoot 200 yards does not mean your gun and that load will group well at that distance. I would really be leary of it with a 245 grn power belt. That is most likely one short, fat bullet. I don't think you will have to worry about shooting over a deer at 30 yards though with a farther sight in range.
I will run a few thru a calculater so you can get an idea of what you would be looking at. I don't have a clue what the BC of a 245 grn powerbelt is, and couldn't find it on the net. I am going to go with .200 which I think should be close. It shouldn't change figures that much any way at these distances and speeds.
With that bullet and powder charge you should be getting around 1600-1700 fps, I will use 1650. If you actually know how fast it is shooting that would help. I am also assuming you are using a scope and it is around 1.5-2 inches above your bore. This makes a big difference on trajectory. If you don't have a scope or it is lower or higher let me know. I still don't think it will change enough to make that big of difference though.
I personally have my inline sighted in at 130 yards because I have a max distance of 150 yards. With my bullet and powder combination that lets me be point blank out to 150 yards. ( 3 inches high at the highest, and 3 inches low at 150). I shoot 350 grn PR QT bullets though. I will run number for you at 50, 75, 100 and 150 sight in points. And let you know the impact points at 25, 50, 100, 150 and 200 yards.
It will take me a few minute to run all the numbers and type it all up, maybe half an hour.
