Very interesting, and further confirmation of my long-held conviction that the price of a short, handy barrel may not always be as high as many folks believe.
Re: Another Barrel-length vs. velocity article
thanks for posting this.
for 45/70 I give up 100 fps in my guide gun for a 405gr load. I'll take that. Their shortest barrel is still way faster than the 405 44s out of my redhawk.
those loads are a interesting. I have a 425 gr load going faster than their 405, and the 325 load seems slow to me.

Re: Another Barrel-length vs. velocity article
Proof that some of the strongly held opinions which I have read are not always backed up when science is used to check it out. I have seen in many articles that there is a loss of velocity of 100 fps per inch of barrel loss. Seems as if a good chronograph says that velocity loss is caliber as well as barrel length dependent. There must be more involved than just barrel length and caliber.

Re: Another Barrel-length vs. velocity article
Yep. I think it depends essentially on the volume of the combustion space just prior to bullet leaving barrel versus the volume of the cartridge, plus on top of that the burn-rate of the powder. Certainly incremental the velocity gain per inch of added barrel drops off once you get much past a foot for the common cartridges and loads we use.
Stubby, minimally vibrating barrels, and long, sight-radius-enhancing barrels both increase chances of a hit though, muddying the waters further, then on top of that, shorter barrels fatigue the arms less for a steady hold, yet longer ones have more inertia, and contribute what some folks refer to as 'hanging on target better'.
No one answer best for everyone, but it helps us make decisions to have the data.
Glad they did one for 444 Marlin; an under-appreciated caliber in my opinion.
