    I went shooting my Rossi trifecta 22lr at 50 yds to compare various ammo.
    I adjusted the scope so that the Rem. Golden bullets were dead on. I was getting about 1" groups. I then tried some Velocitors. These grouped about 2" low and also 1" groups. I also tried some Win. Expeditors(Stinger clones 1640 fps). These didn't group well but were about 3" high.

    What mystifies me is why the velocitors at 1435 fps would impact below the golden bullets at 1280 fps. What am I missing here? Faster bullet should hit higher right?

    Velocity is claimed, so actual may vary.
    Were all bullets same weight?

    If the bullit is the same whieght but a higher MV it will leave the barrle sooner, so the muzzle lift will be at a LOWER point, this will cause the POI to be lower. Find your best grouping load then adjust the sight's as needed.

    Is it that simple? If the velocity of a given bullet is greater, isn't recoil also greater? So despite travelling through the bore faster, couldn't the muzzle be higher by the time the faster bullet actually exits?

    I know this is true in a handgun for a heavier bullet, velocity being constant. Seems like it should work the same for differing velocities where bullet weight is constant since momentum is just the product of mass and velocity.

    velocitor=40 gr
    golden bullet=36 grains
    expeditor= 32 grains

    I like others have had many misfires in semiautos with the goldens. They worked very well in the single shot Rossi however. I was getting many bullseyes when I could hold steady enough. Same with the velocitor when I held 2" high.
    Next I need to try the Aguilas.

    I could get good groups from Remington Golden Bullet bulk pack in my 10/22 if I could put up with the misfeeds or single load them (PITA). I quit buying the stuff too many duds in my pistols.

    Try some Wolf Match .22.

    rollis is mostly right here, and the thought of muzzle rise and bullet speed is mostly wrong; the same way a semi auto fires a bullet, and the bullet is leaving the bbl, before the gas expands enough to start the reward travel of the bolt-
    your bullet will be leaving the bbl way before the muzzle flip has any impact on the bullet's flight. Especially considering the weight and length of the bbl, to keep any recoil from a 22 lr down.

    A 100 gn. bullit moving at 100 fps should produce less recole (real and perceved), than a 200 gn. bullit, becuse there is less energy needed to over come the enerta of the bullit. As soon as the poweder is ignighted there is recole, the energy of the forward movement of the bullit, also produces a rearward movement of the rifle. This then translats into muzzle rise.

    Recoil force is proportional to muzzle energy, not velocity alone.

    GB: 131 ft*lbf
    Velocitor: 183 ft*lbf
    Expeditor: 191 ft*lbf

    Regarding muzzle rise: how are you shooting? Sandbags? Prone?

    I wonder if scope height may also be doing something here as well.
