Is there a BDC or dot type scope that is a good match for the HMR? I know it is a bit redundant as around 300 would still be the maximum range at least for me.
This is taped to the objective bell of the Leupold 3.5-10X40 B&C on my 17HMR. This is only as complicated as you make it.
Any trajectory program will get you close, then it's a simple matter of verifying and tweaking drops. Same as for a BG rifle.
P.S. Sorry it is so large.
