Re: Short thin barrels for long range?
Okay, having read the article, I can make a better assesment here, and what he's saying is for the most part true, but requires some reading between the lines. His assesment about stiffness between a short and long barrel is perfectly correct, but assumes barrels of the same O.D. dimensions. The comparison between a longer heavy barrel and a short lightweight tube is where it gets dicey. Lots of other stuff going on here, and I wouldn't buy this as a simple blanket statement. The way he words it here, he makes it sound like the 1000 yard shooters are missing a bet by using 30" barrels on our Palma rifles. I guess we'd be much better off with 16.5" lightweight barrels, but we're just too dumb to figure that part out.
Same situation with the expansion ratio I mentioned earlier; it's ONE of the factors that goes into the velocity equation. Changing barrel length may make a considerable difference, or be completely unnoticeable in the field. It all depends. Again, blanket statements that are far too broad to be resolved with a simple "Yes" or "No" answer.
I think he would have done his readers a better service by merely using the space to explain why he likes short, lightweight hunting rifles, rather than trying to make some specious ballistic arguments.
