4Seventy, all you just did was take two pages to say the same thing I just posted! Congratulations!

Nobody said anyone knows WHAT the barrel time is exactly, and it doesn't matter, as you say. We know it is too slow, or too fast by the way the bullets print on the target. Barrel time, for all practical purposes, only comes into play if paired with recoil. That is what I was trying to say in relation to the little .22 lr, in a 7 lbs double rifle, it can be disregarded for the most part, because it has so little recoil that the barrels simply have to be spread, or norrowed till they shoot to the same POI, and do not have to be converged till the line of sight crosses, and points low. They do not have to point on opposite sides of the aiming point,and low, to regulate, as a rifle with recoil would. Any rifle that has a lot of recoil, if a lazer is placed in each barrel, the line of the static bore sighting, would print a spot on a target as low, and left of POI, for the right barrel, and low and right of the POI on on the target for the left barrel, with the iron sights on POI. With a cartridge like the .22 lr, they can both be almost paralell. All I'm saying is, the 22 lr wouldn't be hard to regulate at all, because barrel time plays so little there, because it has no recoil to be paired with, plus being slow.

4Seventy, we are saying the same thing, just useing different words. I have no idea if you have ever built new barrels for a double rifle, or have physicly re-regulated a set of barrels to a different load, but I have no doubt you could, given your apparent working knoweldge of the idiosyncracies of double rifles. I have, however built a number of barrels for doubles and physically re-regulated many more, for different loads,over the years. My regulations have historicly printed four shots in no more than 3" at point of regulation,usually 100 yds, but some of the larger calibers at 50 yds. So I think I understand the process, as I'm sure you do! I think we are preaching to the choir by telling each other how it is done. That isn't all bad, however, because there are many here who do not understand it, and may benifit from our banter!
