Everyone loves a accurate rifle!!
4" drop with a 50 yard zero sounds about right. But remember a bullets track is a arch and comes from a scope that is mounted approx 1.5" above the bore. SO, siting it shoot about 1/2" high at 50 yards, is gonna bring that 100 yard impact allot closer to zero. (as suggested
)
I have had a on again off again thing with the 22Mag. I had a fair shooting Ultra Varmint 22mag and bought a 17HMR. Well the HMR was so much more accurate I did not "need" the mag anymore. That was a couple years ago... Last year I have a new piece of property with a Coyote problem. but its somewhat populated so CF rifles are not approprate and the 22M is taylor made for this. I found another 22M barrel and got lucky, it shoots my favorite 50G Federals.
Best of luck with your shooting!
