My truck gun for ground squirrels is a New England Firearms single shot with a Leupold 3.5x10. Checked it out yesterday after missing some easy shots. Over a solid rest, it's right on at 25 yards, but about an inch low at 12 yards with Hornaday 17 grain bullets. I've looked at trajectory charts that show the over/under bullet path for 100 yard zero. One chart and table for the 17 grain shows 1.5 low at the muzzle, .48 low at 25 yards, .15 high at 50 and .34 high at 75.
So I understand that the bullet crosses the line of sight twice between the muzzle and 100 yards. but an inch difference between 12 and 25 yards seems excessive? Extrapolation from the chart would indicate perhaps the 1 inch difference is normal?
I only shoot nuisance rodents on my own property. Most of my shots are between 10 and 35 yards. My advanced age and infirmities mean I can't hold close enough for longer distances. I can only shoot 3/8" to 1/2" groups at 25 yards. I understand the cartridge/rifle/scope combination is capable of much greater accuracy but I am not.
Any advice about sight in distance or other corrective measures would be appreciated. My current plan, absent input here, is to hold over on the closer shots.
