I have a Rossi m92 ,24 inch octagon barrel.I just bought it and took it to the range. The rear sight bottomed out with 260gr.bullets is dead on at 25yrds.2 inch's high at 25yrds with 315gr bullets. At 100yrds the 260 is dead on at 100 bottomed out but 315 is 6 inch's high. Can any one tell me what front sight height is too little or to much? The front sight is .310 on my calipers.

store.stevesgunz.com/You might contact Steve Young. He does nice work on the Rossi lever guns and might have some input on proper front sight height for the heavier bullets.

Figure out what height sight you need using the sight correction formula. Amount of error x sight radius divided by distance to target in inches. That will give you the amount of adjustment you need for the front sight. Not knowing you exact sight radius. I guessed at 22". So you would need approx a .050 higher sight. So a .375 would probably give you some adjustment with both loads. |

Problem solved I took a picitany rail dremiled out a Grove so I could mount a savage 22 peep sight in the Grove that is adjustable .then Tig welded the rail to the dovetail drilled and tapped the dovetail to lock it in to the dovetail in place to keep it from floating.the nice side effect is now I can mount a light scope or red dot.And I have a peep sight back up. I will take it out to the range and see if it can take the abuse from 300 grain bullets at 22 grains of h110.
