PH,
Let me also welcome you aboard.
Most of the charts your looking at are for when the center of the scope sets 1 1/2 in. above the center of the bore. If your`s is less you can expect alittle more drop at 200 yrds. and if it`s higher you can expect alittle less drop. Checking my charts you should expect about 6 in. if your 150 gn. bullet is fired at abt. 2,400 fps. Factory loads should be around 2,900 fps. from a 26 in. barrel and if you lose 125 fps. for each in. of barrel that would put you about right on. BUT,,, you should lose only about 50 fps. per in. I`m not really sure what is happening and don`t know if I could if I seen your set-up, but as long as you know where your gun is shooting that`s really all that matters.
