    Data needed for 22LR 16" Ruger 10-22

    I am looking for fps of different 22LR out of a Ruger 10-22
    Also the BC would be great.

    Thanks guys

        Wonder what the BC is at your speeds compared to the speed of the 26" barrel they use to get data

                      What are you talking about? BC is listed for all centerfire bullets. BC is not dependant on velocity. Where on the box, chart, etc. does it list BC vs velocity? There's some phenomena in subsonic vs supersonic, but when you're starting out barely supersonic the numbers are what the numbers are.

                      The formula for calculating the ballistic coefficient for bullets only is as follows:[2][3]
                      BC_{Bullets} = \frac{SD}{i} = \frac{M}{i \cdot d^2}
                      where:
                      BCBullets = ballistic coefficient
                      SD = sectional density, SD = mass of bullet in pounds or kilograms divided by its caliber squared in inches or meters; units are lb/in2 or kg/m2.
                      i = form factor, i = \frac{C_{B}}{C_{G}}; (CG ~ 0.5191)
                      CB = Drag coefficient of the bullet
                      CG = Drag coefficient of the G1 model bullet
                      M = Mass of bullet, lb or kg
                      d = diameter of bullet, in or m




                      Notice no "v" or "s" in the above equation?

                      The term "coefficient" implies a constant for a given object (in motion or at rest).

                        I had heard that the average .22lr would begin to actually slow down after about 18". The powder is all burned and the pressure will begin to drop off and the bullet begins to be slowed by the barrel friction.

                        so i don't think anyone is getting velocity figures out of a 24 or 26 inch barrel.

                          There's always variables (ammo, barrel, etc.), but that's pretty much the truth.

                          Here are the results collected by Bob Forker. These are muzzle velocities
                          for barrels of different lengths (determined by cutting the barrel between
                          test batteries):

                          Barrel Length Remington High Velocity Winchester T22
                          4 in 1045 fps 1005 fps
                          8 1150 1105
                          12 1220 1155
                          16 1240 1165
                          20 1235 1160
                          24 1210 1140
                          28 1170 1075

                            You would think rather than swapping powder you'd be looking at a projectile with a better BC. Like a .223 40 gr spritzer.

                              Not correct. BC is dependent on velocity, hence why some bullet manufacturers provide BC's for different velocity ranges, and why ballistic programs allow you to put in multiple BC's for varying velocity ranges.

                              Oh and there is a "v" in the equation above, it is just in the drag coefficient. http://en.wikipedia.org/wiki/Drag_coefficient
