Hey all. I remember reading/seeing an article posted by Lee Jurras a number of years ago. I was a ballistic test that he did with a revolver. He did his test(s) then cut an inch off the barrel and did more tests. I believe the barrel started at 8" and he cut it down to 2". I remember seeing the revolver setting on a table with the 1" cut off pieces. I have been searching this site and Ian's other site and cannot find the article. Any help pointing me in the right direction would be greatly appreciated. Thanks!

If you were happy and you knew it, would you clap your hands?

I remember reading that article. If not mistaken the title was something as "The long and the short of it" and I tought it was in the shooters bible or a gundigest.
If I can find some time tomorrow I zip through my old bibles... Hope this helps.

Thank you. I will do some searching for that. If you find it before I do, please post the link? If I find it before you do, I will do the same. |

Sadly, the reprinted article seems to be incomplete. It goes into great lengths to describe the testing protocol, and then just stops. I assume additional missing pages reveal the results of the experiment?

My Google Fu allowed me to find the remaining missing text, which you can read here:
I�ve shot lots of .44 Magnums, over 5,000 full-charge loads at varmints alone during the past year. Recoil and blast have never bothered me, even when function-firing 4-inch guns as fast as possible for over 100 rounds in just a few minutes. But, at the 3 and 2-inch lengths, the test gun began beating my hand badly; the front of my trigger finger was first blistered, then bloodied, from the inside front of the trigger guard; my index finger the same from the rear of the trigger guard; little finger smashed between gun-butt and sandbag; and the entire hand, wrist, and forearm strained and painful from the cumulative effects of recoil in general. Eventually I began flinching but fortunately only with the test gun; flinchitis didn�t carry over with other guns after the tests.
To state that recoil with the 2-inch barrel was vicious is putting it mildly, to say the least. Four inches is fine, and I�m accustomed to it, but that 2-inch Ruger simply beat my hand to a pulp. This is not a criticism of either the gun or cartridge; this was simply an experiment, and certainly there is no practical use for a barrel shorter than 4 inches by any stretch of one�s imagination. Ammunition was chosen for the tests based upon general availability to the shooting public, including the new R-P �medium velocity� load which has long been needed. The Norma load was used only in the shorter barrel lengths because from past experiences it was expected to be faster there then the others; this was proven true. One lesson learned from the tests is that none of the loads showed any great velocity gain beyond 7 inches of barrel � less than 100 fps gain from 7 to 10 inches. That�s not much return for the investment in an extra-long custom barrel. Another lesson is that velocities are higher than we expected from barrels under four inches and a good bit lower at 4 inches than most .44 shooters have believed. TEST RESULTS BBL.
