Re: Long range barrel profile
[ QUOTE ]
These loads were tested in several Palma rifles with different actions but all had 5- to 6-pound 30-inch barrels with tapers much like those I mentioned earlier about 1.2 inches at the back and about .800 at the muzzle.

I think this may be the root of all the misunderstanding here. Not meaning to flame anyone, but this is LONG RANGE HUNTING, not long range Palma. Many principles of Palma do not correlate directly to benchrest or 1k br or hunting. Typically, when people here speak of skinny barrels, we are talking about .5" muzzles in #4-6 contours. Not barrels that are 30 inches long and .8"+ at the muzzle! THis is roughly the size of my 1760 yard 6.5-.284 that weighs in at 20 pounds! I wouldn't ever call this a pencil barrel. It (and the barrels you used in your example) obviously have enough rigidity to shoot small groups consistently <font color="red">because they are not whippy. </font> If this had been established at the first, this whole thing could have been recognized earlier as a incorrect use of terms rather than a debate about fundamental principles of metallurgy!
ALso you state:

Consider what happened in 1991. The US Palma Team Captain asked in late 1990 if I and several other former Palma team members would help develop the ammo to be used for the 1992 World Long Range and Palma Championships.

Again, not to hurt anyones feelings, but Palma ain't the end all solve all of disciplines. There are things done there that would never be utilized in any other shooting sport. ANd, many many things have changed even in Palma since 1991. A dozen new powders have been introduced, a couple dozen new cartridges have proven themselves worthy of 30+ new world records, several different experiments in twist rates and barrel making procedures have revolutionized the industry, and a host of new bullets with extra long coefficients have been utilized to attain accuracy that was thought 15 years ago to be impossible.
ANd one last thing I would like to add. Today, I found a load in a 308 with 155 grain Berger VLDs and N133 that shot a standard deviation of 2 feet per second. Obviously, the bullets all left the barrel as close to the same velocity as one can humanly get. THe barrel measured .476" at the muzzle and was 22" long. Now, some might think that they should have gone in the same hole with them leaving the muzzle at virtually the same velocity. BUt, they DID NOT. It shot just over 1" at 100 yards.
WHy? Because, the barrel and about 1 million other things factored into the reality that there are real world experiences and then there is armchair theory that looks good on paper.
JUst my 2 cents.
PS. BTW, my highly skilled, local gunsmith had a statistician and a structural engineer run the numbers on the REm 700 vs. the Win M70 and came up with differing results than what you have stated. SOme tests need to be run over and over again by different parties to be sure of a result. One individual test really doesn't mean piddly. [img]/ubbthreads/images/graemlins/wink.gif[/img]
If it's not far, it's boring.
