Roll EyesThe thought was that the extra 2" of barrel was responsible for the 200+ feet per secound difference between the two rifles.
Well I did my home work and ran the calculations. Being an engineer I can do that, you see. flame Not attributing any loses do to friction or heat transfere the most these two 22-250s could differ was 97fps.the other 125 ft/sec. or so came from some where else.
ConfusedCould I have made a mistake? Yes, but not to any large degree. sofaroger


Old age is a high price to pay for maturity!!! Some never pay and some pay and never reap the reward. Wisdom comes with age! Sometimes age comes alone..

Who cares?

I always want to know what MY rifle is giving me for a velocity...

not what someone else's is giving him.....

when testing 15 different powders in a 6mm Rem with a 75 grain HP Hornady bullet...

the most accurate load, was with 47.5 grains of H 414....

however on chronographing it, I found that it also had the greatest velocity spread of any of the loads! 150 to 175 fps standard deviation..

I just load it and shoot it, and out to 300 meters, the groups just keep being small and itty bitty..

so what is to worry about???
