Hi ALL,
I was wondering if or how any of you have worked the relationship between the barrel length, burn rate and velocity into your reloading. It seems to me that in order to get a higher velocity one would normally use a slower burning powder as a rule of thumb. But it seems that this relationship is also dependant on the barrel length of the firearm and in some situations a faster burning powder will give you a higher velocity in a shorter barreled firearm than a slow burning powder. This seems to me to be most evident when I am reloading for revolvers and I compare my 6 or 7.5 inch barreled revolvers to my 2" barreled revolvers. The goal is to get a complete burn inside the gun and produce the maximum velocity possible for that short barreled gun. I think a large fireball outside the barrel is indicitive of a less efficient load.
Right now I am trying to get better velocity form those short barrreled revolvers. While a load of H110 or 2400 will produce the highest velocity in my 6" .357 mag, Unique might produce higher velocity in my 2" barreled .357, because more if it burns inside the gun as evidenced by the huge fireball H110 produces versus the much smaller fireball produced by Unique.
Has anyone done any experimentation with this idea????
