RE: 50 cal inline w/ 3-9x40 scope sighting in range
I sight in 2 1/2 high at 100...about 2 inches high at 50 and about 2 inches low at 150...using a Knight Disc..22 inch barrel and 90 grs 777 and 250 Hornady SST...
Only real way to know, is work up a load your gun likes and try at various ranges....Good luck
