Why would a Mossberg 4x4 Rifle's scope max out on windage and elevation at 25 yds.?
And i no im dead on with my sights because im using a boresighter but i already had it sighted in at 25 yards and i was just checking it and it was off so i tried re-sighting it in with my boresighter and both the windage and elevation were maxed out and it was so off sighted but i cant get why its doing that. please answer quick
At 25 yards there is no way to properly "sight in" your high power rifle. For the most part the Rifle Barrel has a slight positive angle to loft the bullet a little (every bullet is immediately influenced by gravity when it leaves the barrel),so there is an "apparent" positive ballistic curve.When this is coupled with the slight negative angle (in relation to the barrel) of the scope line of sight you should have two intersect points along the curve-and at 25 yards you aren't there yet. Then you have to take into account the normal 1.5 inch distance from center of barrel to center of scope (more on a high mount ring set). Each click in the Windage/Elevation adjustments equals 1/4 MOA while that is 1/4 inch approx at 100 yards (1/2 at 200,1 inch at 400) it is only 1/16 on an inch at 25 yards No wonder you don't have any adjustment left if you weren't near center to begin with.
I suggest you bore sight then move out to 50 yards,shoot to get on paper,adjust,then take a second shot at 50 and adjust better. Now take three shots and adjust the CENTER OF THE GROUP to be closer to center of the target. Move the target to 100 yards,take one shot and adjust towards center,then take three shots and adjust the center of the groups again. If this is a hunting rifle I suggest you actually plan for a 200 yard ZERO,which is much closer to the Max Point Blank Range on most high powered rifles,so plan on being about 2 inches high at 100 yards. Doing that will not effect your aim point on a game animal at under 200 yards and makes a 300 yard shot not as difficult. If this is a 100 yard target shooter,or a longer Range Target shooter you adjust to those ranges as best possible.
I reload for 223,243,30-06 and 300 WSM,and I have to work up loads for those rifles and others,so I know that trying to sight in at 25 yards with anything more powerful than a 22LR is futile,in fact sighting in at 200 yards is much easier once you know where your first shots hit,but I just don't like walking that far for targets.
