| Looking for info on software with the capability to calculate velocity for varying barrel lengths in a good range of calibers. All of the ballistic data I've been able to find is tested on a 24" barrel. Thanks for any info. |

I was using QuickLoad for a while. It's an internal ballistics program where you can play around with powder charges, barrel lengths, seating depth and many other variables to see what the "theoretical" muzzle velocity will be. It's was pretty accurate with my 7 Rem Mag loads and basic 308 Win stuff. My version isn't compatible with Window 7, though, so I haven't used it in a while. CHRIS |

CHRIS Can't you run it in compatability mode? OP Quick load is the one for you. It also includes the exterior ballistics program Quick Target. |

As others have pointed out, QuickLoad is a handy analytical tool. It is good for parametric studies like varying barrel lengths.
For instance, if you were chronographing a 16" AR and comparing it to 24" test bbl data, you could plug in your 16" AR round in QL and run computed Muzzle Velocity for bbls in 16, 18, 20, 22, and 24. Then use the increments of increasing MVs to step up your 16" AR chrono results to an extrapolated 24" AR result. Then compare the extrapolated 24" AR to the published 24" test bbl data. That technique is not perfect, but will get you close. There are other effects like gas port locations and gas bleed in the ARs where the test barrels are usually no-vent bolt guns, that will taint the comparison. If you look closely, you can find some 14", 16", and 20" bbl published data for the ARs. You can also find 24" AR10, 22" M1A, and 16" SOCOM data for the same round. Molon and others have published some MV chrono data for various bbl lengths over on AR15/Ammunition forum. |

Run it either in compatibility mode or download the free xp virtual machine and install that. Then install QuickLoad on the VM. If you're not familiar with the process you do is go to the Micosoft website, download a few programs, install and you can start the xp virtual machine anytime you want from within Win7. Install, run or delete programs as you normally would on a typical xp machine. It's really very simple.

CHRIS i think you can send the disc back to them and they will send you one compatible or just use virtualbox to run xp www.virtualbox.org
