I have a question that may sound silly however in my pea sized brain I have been thinking about this. The sights on mounted on top of the slide assy. The bore is below the sights meaning the bullet and the sights have to have a place to intersect in order for the two to co-inside. Meaning at what point do the bullet and the sights become the same. I know a bullet rises and falls, especially on rifle however we are talking about a longer distance. How far does the bullet have to travel (230 round nose) before the lines become the same or what I call the intersection point. My groups are good at 30-40 feet however 2-3" low. Ruger checks their sights at 15 yards. Baer, Wilson and the high dollar gun producers guarantee 3" group @ 50 yards which is far more than I can see with my old eyes. My groups average 1 1/2"-2" at 35-40 feetalthough low. Is my bullet still going to rise at the 50 yd distance or will it maintain the present trajectory? If anyone can help me, please advise. Lowing the front sight 2/10,000ths will raise the bullet 1" per 25 yards according to Novak. Jim, you have a lot of rifle experience and will understand bullet drop more than most I think. It has been over 20 yrs. since I shot rifle and I have forgotten most of what I can remember, or possibly Buster or someone else. Can anyone help me???? I forgot, but I think it's called bullet compensation. Am I right??
