    I can get very good groups at 25 yards 300 grain bullet but when i switch to 350 or 400 its not even close do i need to get sight adj for each bullet?

    Are you saying you are not geting good groups with 350 gr. or 400 gr. bullets? Or are you getting good groups but not on target?

    Changing bullet weights will change your point of impact, and yes, you need to change your sight seting to compensate for the difference.

    I had the same problem with the .44 Magnum using 180 gr. and 240 gr. bullets.

    I solved the problem by buying two different revolvers and sighting them for the different bullets. Then bought different grips to tell them apart.:):):):)

    Catching the topstrap with your forehead will do that to a feller! ;)

    New shooter?? Same thang happens with a 357mag or 44 or !!!! Pick one bullet to shoot or log the different loads so you can adjust depending on the load used. Guess you bought it for grizzly?? pick a heavy hardcast and be done with it unless you carry some 500 sp loads for thin skinned hunting too. If you have a centefire rifle and you change bullet weights are even brands you will have to re-adjust your sites.

    Yes.
    Different weight bullets are going to shoot to a different point of impact, that's simply a fact of life. Take good notes, or pick one load and stick with it.

    grizz you picked a heck of a revolver to learn about bullet weights and where a bullet stricks when you change anything. Start with a .22lr. The differnce between a 22 short and 22 standard velocity and a stinger at 25 yards will teach you the same thing.

    Generally speaking, a heavy, slower bullet will impact higher than a light, faster bullet. Believe it or not, the upward recoil forces will actually have the gun poiniting up before the bullet leaves the muzzle.
